The key is to define clearly what each method is responsible for.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\">TOC <a href=\"https:\/\/www.stockm.eu\/en\/buffer-inventory-management\/\">buffer inventory management<\/a> should be the primary approach for day-to-day inventory decisions. It uses actual consumption, current inventory levels, lead times, and changes in inventory buffers to show which items require immediate attention. This is the level at which businesses decide what to replenish, which stockout risks to address first, where stock should be transferred, and where inventory protection levels need to be reviewed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\">Forecasting plays a supporting role. It helps businesses prepare for future events before they appear in normal consumption patterns: seasonality, promotions, new product launches, tenders, major customer projects, expected market changes, and supplier capacity commitments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\">This is not a choice between <a href=\"https:\/\/www.stockm.eu\/en\/toc-inventory-management-vs-min-max\/\">TOC inventory management<\/a> and forecasting. It is a question of which method should be used for which type of decision.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\"><strong>The TOC method manages day-to-day inventory execution. Forecasting helps prepare for the future.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\">When this distinction is clear, a company can protect product availability and use working capital efficiently today, while preparing in advance for important changes ahead.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-theme-primary-color has-text-color has-link-color wp-elements-2\" style=\"font-size:24px;font-style:normal;font-weight:500\"><a><\/a><a>Why should the TOC method be the foundation of daily inventory management<\/a>?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\">Daily inventory management is about taking practical, timely action. Every day or during each planned replenishment cycle a company needs clear answers to questions such as:<\/p>\n\n\n\n<ul style=\"font-size:16px\" class=\"wp-block-list\">\n<li>Which products are currently at the greatest risk of running out?<\/li>\n\n\n\n<li>Which items should be replenished first?<\/li>\n\n\n\n<li>Which products have already been ordered or are currently in transit?<\/li>\n\n\n\n<li>Which supplier delay is having the greatest effect on product availability?<\/li>\n\n\n\n<li>Which items are holding more inventory than current consumption requires?<\/li>\n\n\n\n<li>Which inventory-management settings should be reviewed because real conditions have changed?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\">This is done under dynamic conditions. Customer demands occur at irregular intervals, demand levels vary depending on location, delivery times by suppliers may vary, substitution of products may take place, promotions may not yield the desired results, and a large customer order may be delayed by a few days or weeks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\">Forecasting may help in understanding such scenarios. Nevertheless, forecasting alone cannot capture all such changes in a constantly changing market.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\">TOC inventory management is a perfect choice for this type of operating environment. It uses actual consumption and the current inventory position to guide replenishment and prioritization. The inventory buffer provides the level of protection needed while stock is being replenished. Over time, buffer behaviour shows whether that level of protection still reflects current supply and demand conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\">In TOC method replenishment, actual consumption is the main signal for replenishment. The aim is to maintain product flow using current information, rather than replenishing inventory simply because a forecast predicts a certain quantity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-theme-primary-color has-text-color has-link-color wp-elements-3\" style=\"font-size:20px;font-style:normal;font-weight:500\"><a>What does TOC dynamic buffer management do in practice<\/a>?<\/h3>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">TOC inventory management helps teams focus on the decisions that influence product availability and inventory investment today.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" style=\"font-size:18px;font-style:normal;font-weight:600\">Replenishment priorities<\/h4>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">A company with hundreds or thousands of SKU-location combinations cannot give every item the same level of attention. TOC uses <a href=\"https:\/\/www.stockm.eu\/en\/toc-buffer-zones\/\">buffer status<\/a> and the current inventory position to highlight the items that matter most.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">This allows inventory planners to prioritise products where action will have the greatest impact on customer service, production continuity, and product flow.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" style=\"font-size:18px;font-style:normal;font-weight:600\">Replenishment quantities<\/h4>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">TOC method helps to calculate the amounts needed to replenish based on where the item stands and the target amount, which is called the buffer. In determining and suggesting quantities for replenishment, other factors like the replenishment rate, outstanding orders, lead time, and purchases are also taken into account.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">Instead of calculating numbers manually for each item, planners can look at replenishment suggestions and pay more attention to items that need business decisions.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" style=\"font-size:18px;font-style:normal;font-weight:600\">Supply risk and lead-time changes<\/h4>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">Supplier delays can distort the expected availability of products and create a risk of stockouts. A TOC inventory management system helps the team identify which items require attention first and investigate the causes behind emerging shortages.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">This gives purchasing teams a clearer basis for deciding whether to expedite a delivery, escalate an issue with a supplier, or use a suitable substitute.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" style=\"font-size:18px;font-style:normal;font-weight:600\">Excess inventory and working capital<\/h4>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">TOC is not just about avoiding stockout problems. It also serves as a method to determine items for which inventory is constantly held much higher than what is actually needed according to consumer demands.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">Such an excess uses up capital and should be addressed properly. The company could try to get better supply terms, lower the buffer, sell more aggressively, reprice the product, or prepare to discontinue it.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">This allows for a focused approach to freeing up capital for more important items.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" style=\"font-size:18px;font-style:normal;font-weight:600\">Continuous adjustment<\/h4>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">Demand and supply conditions change. TOC treats the inventory buffer as a parameter that should be reviewed based on actual behaviour.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">Recurring shortages may indicate that the buffer needs to be increased, replenishment frequency should change, lead-time assumptions need to be reviewed, or supply arrangements should be improved. Persistent excess may indicate that the buffer can be reduced.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">This feedback mechanism allows inventory settings to develop alongside the real operating environment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-theme-primary-color has-text-color has-link-color wp-elements-4\" style=\"font-size:20px;font-style:normal;font-weight:500\">Where forecasting supports TOC?<\/h3>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">However imperfect forecasting may be, it is difficult to eliminate entirely in real business conditions. It is especially important when a company needs to make decisions before actual product or raw-material consumption is visible.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">Forecasting is therefore most useful when discussing future events and preparing for them.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" style=\"font-size:18px;font-style:normal;font-weight:600\">Seasonality<\/h4>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">The organization can also be aware of the fact that there is increased demand for heating equipment prior to winters, gardening equipment prior to summers, and certain food items prior to holiday seasons.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">With forecasting, the organization gets prepared in advance by stocking enough quantity, arranging transportation, assigning space in the warehouses, and determining seasonal stock levels.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">When the season starts, TOC takes care of managing on a daily basis. The real consumption and the buffer status help determine where action is needed.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"546\" src=\"https:\/\/www.stockm.eu\/wp-content\/uploads\/2026\/09\/forecasting-vs-dynamic-buffer-management.webp\" alt=\"Forecasting vs Dynamic buffer management\" class=\"wp-image-6484\" srcset=\"https:\/\/www.stockm.eu\/wp-content\/uploads\/2026\/09\/forecasting-vs-dynamic-buffer-management.webp 900w, https:\/\/www.stockm.eu\/wp-content\/uploads\/2026\/09\/forecasting-vs-dynamic-buffer-management-300x182.webp 300w, https:\/\/www.stockm.eu\/wp-content\/uploads\/2026\/09\/forecasting-vs-dynamic-buffer-management-768x466.webp 768w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/figure>\n<\/div>\n\n\n<h4 class=\"wp-block-heading\" style=\"font-size:18px;font-style:normal;font-weight:600\">Promotions and marketing campaigns<\/h4>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">A planned promotion may generate demand that is not yet visible in normal consumption history. Sales and marketing teams can provide information about the expected uplift, campaign duration, participating products, and locations.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">This information helps the company plan a temporary inventory adjustment or a clearly defined exception before the campaign begins. During the campaign, TOC shows whether actual consumption follows expectations and which items require additional attention.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" style=\"font-size:18px;font-style:normal;font-weight:600\">New products<\/h4>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">New products have little or no consumption history. The initial inventory decision may therefore be based on the product-launch plan, comparable product data, sales expectations, supplier terms, and the strategic importance of the item.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">As actual consumption develops, TOC becomes increasingly important. Buffer behaviour shows whether the planned initial inventory level was too low or too high, allowing the company to make appropriate adjustments.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" style=\"font-size:18px;font-style:normal;font-weight:600\">Tenders, contracts, and major customer projects<\/h4>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">A successful tender, contract, planned project delivery, or major customer order can generate demand that falls outside the normal replenishment pattern.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">Forecasting and advance planning help the company prepare supply and inventory for such an event. TOC continues to manage the regular product flow around that exception, keeping exceptional demand visible without distorting routine replenishment decisions.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" style=\"font-size:18px;font-style:normal;font-weight:600\">Capacity, supplier, and financial planning<\/h4>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">Forecasts are also important for decisions with a longer planning horizon:<\/p>\n\n\n\n<ul style=\"font-size:16px\" class=\"wp-block-list\">\n<li>Reserving supplier capacity, especially when suppliers serve many customers and need to plan their production resources.<\/li>\n\n\n\n<li>Implementing annual or seasonal purchasing agreements.<\/li>\n\n\n\n<li>Planning production capacity and workforce levels when higher demand is expected.<\/li>\n\n\n\n<li>Planning warehouse and transport capacity.<\/li>\n\n\n\n<li>Preparing financial budgets and cash-flow forecasts.<\/li>\n\n\n\n<li>Assessing category-growth and category-decline scenarios.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">These are planning decisions. TOC inventory management provides valuable input through actual consumption, availability trends, lead-time behaviour, recurring shortages, and excess inventory. Forecasting, however, remains the primary tool for preparing for the future.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-theme-primary-color has-text-color has-link-color wp-elements-5\" style=\"font-size:20px;font-style:normal;font-weight:500\">TOC First, forecasting second: a practical decision framework<\/h3>\n\n\n\n<figure style=\"font-size:16px\" class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Situation<\/strong><\/td><td><strong>Primary tool<\/strong><\/td><td><strong>Supporting tool<\/strong><\/td><\/tr><tr><td>Daily replenishment<\/td><td>TOC<\/td><td>Forecast only for planned exceptions<\/td><\/tr><tr><td>Stockout risk today<\/td><td>TOC<\/td><td>Forecast can provide demand context<\/td><\/tr><tr><td>Supplier delay<\/td><td>TOC<\/td><td>Forecast supports future capacity planning<\/td><\/tr><tr><td>Excess-inventory review<\/td><td>TOC<\/td><td>Forecast may indicate an expected decline in demand<\/td><\/tr><tr><td>Seasonal preparation<\/td><td>Forecasting<\/td><td>TOC manages execution once the season begins<\/td><\/tr><tr><td>Promotion planning<\/td><td>Forecasting<\/td><td>TOC monitors actual consumption and replenishment<\/td><\/tr><tr><td>New product introduction<\/td><td>Forecasting<\/td><td>TOC becomes more important as consumption history develops<\/td><\/tr><tr><td>Tender or customer project<\/td><td>Forecasting \/ commercial plan<\/td><td>TOC manages routine replenishment around the exception<\/td><\/tr><tr><td>Annual budget and cash flow<\/td><td>Forecasting<\/td><td>TOC provides actual inventory and availability data<\/td><\/tr><tr><td>Annual supplier negotiations<\/td><td>Forecasting<\/td><td>TOC provides data on actual consumption, lead times, and supplier reliability<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">This model helps avoid two common problems:<\/p>\n\n\n\n<ul style=\"font-size:16px\" class=\"wp-block-list\">\n<li>Using a long-term forecast for every day-to-day SKU-level replenishment decision.<\/li>\n\n\n\n<li>Relying only on actual consumption for events that are already known and require advance preparation.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" style=\"font-size:18px;font-style:normal;font-weight:600\">A practical example: preparing for winter demand<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\">Imagine a distributor of heating equipment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\">When it comes to the spring and summer months, the managers do forecasting in order to be prepared for the fall and winter months ahead. There is an analysis of past sales, market expectations, promotions, supplier capacity, transportation capacity, customer commitments, and budgetary constraints. This information helps the company make decisions ahead of time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\">This is where forecasting creates value.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\">Once the season begins, however, conditions may develop differently across product groups and locations. One region may experience colder weather earlier than expected. One product range may sell faster than forecast. A supplier may delay an important shipment. Another category may remain below the seasonal plan.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:18px\">The day-to-day questions then become:<\/p>\n\n\n\n<ul style=\"font-size:16px\" class=\"wp-block-list\">\n<li>Which items face the greatest availability risk?<\/li>\n\n\n\n<li>Which location should be replenished first?<\/li>\n\n\n\n<li>Which delayed delivery will have the biggest effect on customer service?<\/li>\n\n\n\n<li>Which products can continue to be replenished through the normal supply rhythm?<\/li>\n\n\n\n<li>Which seasonal inventory positions need to be reviewed?<\/li>\n\n\n\n<li>Where is stock becoming excessive compared with actual consumption?<\/li>\n<\/ul>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">These are TOC inventory management questions.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">Forecasting helped the company prepare for winter. TOC helps it manage inventory flow throughout the winter season.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-theme-primary-color has-text-color has-link-color wp-elements-6\" style=\"font-size:20px;font-style:normal;font-weight:500\">Forecasts should help plan exceptions, not create permanent noise<\/h3>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">A common practical problem appears when known future events are added to a general daily forecast and remain in the system after the event has ended. This can keep target inventory levels artificially high and lead to excess stock.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">For this reason, such events should be clearly separated and managed as planned, time-bound exceptions.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">For example, a planned promotion can include:<\/p>\n\n\n\n<ul style=\"font-size:16px\" class=\"wp-block-list\">\n<li>The products involved.<\/li>\n\n\n\n<li>The expected quantity or demand uplift.<\/li>\n\n\n\n<li>The affected locations.<\/li>\n\n\n\n<li>The planned start and end dates.<\/li>\n\n\n\n<li>The planned supply or capacity arrangement.<\/li>\n\n\n\n<li>The person responsible for reviewing the exception.<\/li>\n\n\n\n<li>The date when normal replenishment logic resumes.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">This allows the business to prepare in advance while keeping day-to-day inventory management connected to actual consumption.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-theme-primary-color has-text-color has-link-color wp-elements-7\" style=\"font-size:20px;font-style:normal;font-weight:500\">What happens when the forecast and reality differ?<\/h3>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">Mismatches between forecast and reality happen quite often. What is their value? They indicate the areas in which assumptions should be reconsidered.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">In the case when the demand is higher than forecast, the TOC approach allows identifying the priority of availability and necessary replenishment. It is up to the sales group to analyze the nature of demand changes: whether they are temporary, seasonal, for a certain customer, or will persist.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">When the demand is lower than the forecast, the TOC approach reveals the areas in which buffers are now too large compared to the demand.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">In both cases, TOC and forecasting have different responsibilities:<\/p>\n\n\n\n<ul style=\"font-size:16px\" class=\"wp-block-list\">\n<li>TOC manages the immediate operational response.<\/li>\n\n\n\n<li>Forecasting is reviewed to improve future preparation.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This prevents every forecast deviation from becoming a reason to manually change daily order quantities for every item.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-theme-primary-color has-text-color has-link-color wp-elements-8\" style=\"font-size:20px;font-style:normal;font-weight:500\">Inventory management with StockM<\/h3>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\"><a href=\"https:\/\/www.stockm.eu\/\">StockM system<\/a> includes TOC Dynamic Buffer Management methodology to help companies manage their current inventory position through buffer-based priorities, replenishment recommendations, visibility of inventory and supply positions, and reduction of recurring shortages and excess stock.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">Every day, inventory planners see a clear list of the tasks that should be addressed first. These include placing new supplier orders, reviewing products moving towards the red zone, checking late orders, analysing excess items, and deciding on the appropriate action.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">StockM is designed to make inventory management as efficient as possible and help employees focus on the areas where their attention creates the greatest value. Although StockM inventory management is based on TOC principles, forecasting can still be used to set initial parameters or plan an upcoming promotion or seasonal period.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">StockM clearly separates day-to-day inventory management from future planning. This structure allows companies to benefit from forecasting without making every daily inventory decision dependent on a forecast that may no longer reflect current demand and supply conditions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-theme-primary-color has-text-color has-link-color has-larger-font-size wp-elements-9\" style=\"font-style:normal;font-weight:500\">TOC for daily inventory management, forecasting for future preparation<\/h2>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">Many sources present TOC and forecasting as two competing inventory management approaches. In many businesses, that perception is understandable because forecasting is widely used to manage both daily inventory decisions and future planning.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">However, companies often find that using forecasting as the main tool for day-to-day inventory control creates significant uncertainty and instability. This can lead to a familiar cycle: some products are consistently unavailable while others remain in excess.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">TOC addresses day-to-day uncertainty by managing inventory according to the current situation and recommending buffer changes based on actual demand. Buffer status makes it easier to identify the products and situations that require attention immediately, so inventory planners do not need to review every item or rely on guesswork.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">There are still situations where actual demand alone cannot provide enough information. Future planning, such as promotions, seasonal peaks, planned launches, and large projects, requires the company to use available historical data and business information to prepare for what may happen next. This is where forecasting has a clear role.<\/p>\n\n\n\n<p class=\"has-normal-font-size wp-block-paragraph\">Rather than treating TOC and forecasting as opposing methods, StockM customers use them as complementary tools in situations where each adds the most value.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-cover alignfull is-light has-text-color has-link-color editorskit-no-desktop wp-elements-10\" style=\"border-top-left-radius:20px;border-top-right-radius:20px;border-bottom-left-radius:20px;border-bottom-right-radius:20px;color:#000000;padding-top:24px;padding-right:24px;padding-bottom:24px;padding-left:24px\"><span aria-hidden=\"true\" class=\"wp-block-cover__background has-white-background-color has-background-dim-100 has-background-dim\"><\/span><div class=\"wp-block-cover__inner-container is-layout-constrained wp-container-core-cover-is-layout-83bc96ca wp-block-cover-is-layout-constrained\">\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Companies that already use demand forecasting often ask whether it can be used alongside inventory management based on TOC dynamic buffer management.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">It can. The key is to define clearly what each method is responsible for.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">TOC <a href=\"https:\/\/www.stockm.eu\/en\/buffer-inventory-management\/\">buffer inventory management<\/a> should be the primary approach for day-to-day inventory decisions. It uses actual consumption, current inventory levels, lead times, and changes in inventory buffers to show which items require immediate attention. This is the level at which businesses decide what to replenish, which stockout risks to address first, where stock should be transferred, and where inventory protection levels need to be reviewed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Forecasting plays a supporting role. It helps businesses prepare for future events before they appear in normal consumption patterns: seasonality, promotions, new product launches, tenders, major customer projects, expected market changes, and supplier capacity commitments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">This is not a choice between <a href=\"https:\/\/www.stockm.eu\/en\/toc-inventory-management-vs-min-max\/\">TOC inventory management<\/a> and forecasting.

Forecasting helps prepare for the future.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">When this distinction is clear, a company can protect product availability and use working capital efficiently today, while preparing in advance for important changes ahead.<\/p>\n\n\n\n<p class=\"has-theme-primary-color has-text-color has-link-color wp-elements-11 wp-block-paragraph\" style=\"font-size:20px\"><a>Why should the TOC method be the foundation of daily inventory management<\/a>?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Daily inventory management is about taking practical, timely action.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Every day or during each planned replenishment cycle, a company needs clear answers to questions such as:<\/p>\n\n\n\n<ul style=\"font-size:14px\" class=\"wp-block-list\">\n<li>Which products are currently at the greatest risk of running out?<\/li>\n\n\n\n<li>Which items should be replenished first?<\/li>\n\n\n\n<li>Which products have already been ordered or are currently in transit?<\/li>\n\n\n\n<li>Which supplier delay is having the greatest effect on product availability?<\/li>\n\n\n\n<li>Which items are holding more inventory than current consumption requires?<\/li>\n\n\n\n<li>Which inventory-management settings should be reviewed because real conditions have changed?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">This is done under dynamic conditions. Customer demands occur at irregular intervals, demand levels vary depending on location, delivery times by suppliers may vary, substitution of products may take place, promotions may not yield the desired results, and a large customer order may be delayed by a few days or weeks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Forecasting may help in understanding such scenarios. Nevertheless, forecasting alone cannot capture all such changes in a constantly changing market.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">TOC inventory management is a perfect choice for this type of operating environment. It uses actual consumption and the current inventory position to guide replenishment and prioritization. The inventory buffer provides the level of protection needed while stock is being replenished. Over time, buffer behaviour shows whether that level of protection still reflects current supply and demand conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">In TOC method replenishment, actual consumption is the main signal for replenishment. The aim is to maintain product flow using current information, rather than replenishing inventory simply because a forecast predicts a certain quantity.<\/p>\n\n\n\n<p class=\"has-theme-primary-color has-text-color has-link-color wp-elements-12 wp-block-paragraph\" style=\"font-size:18px\">What does TOC dynamic buffer management do in practice?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">TOC inventory management helps teams focus on the decisions that influence product availability and inventory investment today.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px;font-style:normal;font-weight:600\">Replenishment priorities<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">A company with hundreds or thousands of SKU-location combinations cannot give every item the same level of attention. TOC uses <a href=\"https:\/\/www.stockm.eu\/en\/toc-buffer-zones\/\">buffer status<\/a> and the current inventory position to highlight the items that matter most.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">This allows inventory planners to prioritise products where action will have the greatest impact on customer service, production continuity, and product flow.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px;font-style:normal;font-weight:600\">Replenishment quantities<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">TOC method helps to calculate the amounts needed to replenish based on where the item stands and the target amount, which is called the buffer. In determining and suggesting quantities for replenishment, other factors like the replenishment rate, outstanding orders, lead time, and purchases are also taken into account.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Instead of calculating numbers manually for each item, planners can look at replenishment suggestions and pay more attention to items that need business decisions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px;font-style:normal;font-weight:600\">Supply risk and lead-time changes<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Supplier delays can distort the expected availability of products and create a risk of stockouts. A TOC inventory management system helps the team identify which items require attention first and investigate the causes behind emerging shortages.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">This gives purchasing teams a clearer basis for deciding whether to expedite a delivery, escalate an issue with a supplier, or use a suitable substitute.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px;font-style:normal;font-weight:600\">Excess inventory and working capital<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">TOC is not just about avoiding stockout problems. It also serves as a method to determine items for which inventory is constantly held much higher than what is actually needed according to consumer demands. Such an excess uses up capital and should be addressed properly. The company could try to get better supply terms, lower the buffer, sell more aggressively, reprice the product, or prepare to discontinue it. This allows for a focused approach to freeing up capital for more important items.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px;font-style:normal;font-weight:600\">Continuous adjustment<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Demand and supply conditions change. TOC treats the inventory buffer as a parameter that should be reviewed based on actual behaviour.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Recurring shortages may indicate that the buffer needs to be increased, replenishment frequency should change, lead-time assumptions need to be reviewed, or supply arrangements should be improved. Persistent excess may indicate that the buffer can be reduced.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">This feedback mechanism allows inventory settings to develop alongside the real operating environment.<\/p>\n\n\n\n<p class=\"has-theme-primary-color has-text-color has-link-color wp-elements-13 wp-block-paragraph\" style=\"font-size:18px\">Where forecasting supports TOC?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">However imperfect forecasting may be, it is difficult to eliminate entirely in real business conditions. It is especially important when a company needs to make decisions before actual product or raw-material consumption is visible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Forecasting is therefore most useful when discussing future events and preparing for them.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px;font-style:normal;font-weight:600\">Seasonality<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">The organization can also be aware of the fact that there is increased demand for heating equipment prior to winters, gardening equipment prior to summers, and certain food items prior to holiday seasons. With forecasting, the organization gets prepared in advance by stocking enough quantity, arranging transportation, assigning space in the warehouses, and determining seasonal stock levels. When the season starts, TOC takes care of managing on a daily basis. The real consumption and the buffer status help determine where action is needed.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"546\" src=\"https:\/\/www.stockm.eu\/wp-content\/uploads\/2026\/09\/forecasting-vs-dynamic-buffer-management.webp\" alt=\"Forecasting vs Dynamic buffer management\" class=\"wp-image-6484\" srcset=\"https:\/\/www.stockm.eu\/wp-content\/uploads\/2026\/09\/forecasting-vs-dynamic-buffer-management.webp 900w, https:\/\/www.stockm.eu\/wp-content\/uploads\/2026\/09\/forecasting-vs-dynamic-buffer-management-300x182.webp 300w, https:\/\/www.stockm.eu\/wp-content\/uploads\/2026\/09\/forecasting-vs-dynamic-buffer-management-768x466.webp 768w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px;font-style:normal;font-weight:600\">Promotions and marketing campaigns<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">A planned promotion may generate demand that is not yet visible in normal consumption history. Sales and marketing teams can provide information about the expected uplift, campaign duration, participating products, and locations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">This information helps the company plan a temporary inventory adjustment or a clearly defined exception before the campaign begins. During the campaign, TOC shows whether actual consumption follows expectations and which items require additional attention.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px;font-style:normal;font-weight:600\">New products<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">New products have little or no consumption history. The initial inventory decision may therefore be based on the product-launch plan, comparable product data, sales expectations, supplier terms, and the strategic importance of the item.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">As actual consumption develops, TOC becomes increasingly important. Buffer behaviour shows whether the planned initial inventory level was too low or too high, allowing the company to make appropriate adjustments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px;font-style:normal;font-weight:600\">Tenders, contracts, and major customer projects<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">A successful tender, contract, planned project delivery, or major customer order can generate demand that falls outside the normal replenishment pattern.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Forecasting and advance planning help the company prepare supply and inventory for such an event. TOC continues to manage the regular product flow around that exception, keeping exceptional demand visible without distorting routine replenishment decisions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px;font-style:normal;font-weight:600\">Capacity, supplier, and financial planning<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Forecasts are also important for decisions with a longer planning horizon:<\/p>\n\n\n\n<ul style=\"font-size:14px\" class=\"wp-block-list\">\n<li>Reserving supplier capacity, especially when suppliers serve many customers and need to plan their production resources.<\/li>\n\n\n\n<li>Implementing annual or seasonal purchasing agreements.<\/li>\n\n\n\n<li>Planning production capacity and workforce levels when higher demand is expected.<\/li>\n\n\n\n<li>Planning warehouse and transport capacity.<\/li>\n\n\n\n<li>Preparing financial budgets and cash-flow forecasts.<\/li>\n\n\n\n<li>Assessing category-growth and category-decline scenarios.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">These are planning decisions. TOC inventory management provides valuable input through actual consumption, availability trends, lead-time behaviour, recurring shortages, and excess inventory. Forecasting, however, remains the primary tool for preparing for the future.<\/p>\n\n\n\n<p class=\"has-theme-primary-color has-text-color has-link-color wp-elements-14 wp-block-paragraph\" style=\"font-size:18px\">TOC First, forecasting second: a practical decision framework<\/p>\n\n\n\n<style>\n  .toc-table-wrap {\n    width: 100%;\n    overflow-x: auto;\n  }\n\n  table.toc-table {\n    display: table !important;\n    width: 100% !important;\n    max-width: 100% !important;\n    table-layout: fixed !important;\n    border-collapse: collapse !important;\n    font-size: 14px !important;\n    line-height: 1.5;\n  }\n\n  table.toc-table thead {\n    display: table-header-group !important;\n  }\n\n  table.toc-table tbody {\n    display: table-row-group !important;\n  }\n\n  table.toc-table tr {\n    display: table-row !important;\n  }\n\n  table.toc-table th,\n  table.toc-table td {\n    display: table-cell !important;\n    box-sizing: border-box;\n    padding: 8px;\n    border: 1px solid #ccc;\n    text-align: left;\n    vertical-align: top;\n    font-size: 14px !important;\n    white-space: normal !important;\n    overflow-wrap: anywhere;\n    word-break: break-word;\n  }\n\n  table.toc-table th {\n    font-weight: 700;\n  }\n\n  table.toc-table td:first-child {\n    font-weight: 600;\n  }\n<\/style>\n\n<div class=\"toc-table-wrap\">\n  <table class=\"toc-table\">\n    <colgroup>\n      <col style=\"width: 30%;\">\n      <col style=\"width: 22%;\">\n      <col style=\"width: 48%;\">\n    <\/colgroup>\n\n    <thead>\n      <tr>\n        <th>Situation<\/th>\n        <th>Primary tool<\/th>\n        <th>Supporting tool<\/th>\n      <\/tr>\n    <\/thead>\n\n    <tbody>\n      <tr>\n        <td>Daily replenishment<\/td>\n        <td>TOC<\/td>\n        <td>Forecast only for planned exceptions<\/td>\n      <\/tr>\n\n      <tr>\n        <td>Stockout risk today<\/td>\n        <td>TOC<\/td>\n        <td>Forecast can provide demand context<\/td>\n      <\/tr>\n\n      <tr>\n        <td>Supplier delay<\/td>\n        <td>TOC<\/td>\n        <td>Forecast supports future capacity planning<\/td>\n      <\/tr>\n\n      <tr>\n        <td>Excess-inventory review<\/td>\n        <td>TOC<\/td>\n        <td>Forecast may indicate an expected decline in demand<\/td>\n      <\/tr>\n\n      <tr>\n        <td>Seasonal preparation<\/td>\n        <td>Forecasting<\/td>\n        <td>TOC manages execution once the season begins<\/td>\n      <\/tr>\n\n      <tr>\n        <td>Promotion planning<\/td>\n        <td>Forecasting<\/td>\n        <td>TOC monitors actual consumption and replenishment<\/td>\n      <\/tr>\n\n      <tr>\n        <td>New product introduction<\/td>\n        <td>Forecasting<\/td>\n        <td>TOC becomes more important as consumption history develops<\/td>\n      <\/tr>\n\n      <tr>\n        <td>Tender or customer project<\/td>\n        <td>Forecasting \/ commercial plan<\/td>\n        <td>TOC manages routine replenishment around the exception<\/td>\n      <\/tr>\n\n      <tr>\n        <td>Annual budget and cash flow<\/td>\n        <td>Forecasting<\/td>\n        <td>TOC provides actual inventory and availability data<\/td>\n      <\/tr>\n\n      <tr>\n        <td>Annual supplier negotiations<\/td>\n        <td>Forecasting<\/td>\n        <td>TOC provides data on actual consumption, lead times, and supplier reliability<\/td>\n      <\/tr>\n    <\/tbody>\n  <\/table>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">This model helps avoid two common problems:<\/p>\n\n\n\n<ul style=\"font-size:14px\" class=\"wp-block-list\">\n<li>Using a long-term forecast for every day-to-day SKU-level replenishment decision.<\/li>\n\n\n\n<li>Relying only on actual consumption for events that are already known and require advance preparation.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px;font-style:normal;font-weight:600\">A practical example: preparing for winter demand<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Imagine a distributor of heating equipment. When it comes to the spring and summer months, the managers do forecasting in order to be prepared for the fall and winter months ahead. There is an analysis of past sales, market expectations, promotions, supplier capacity, transportation capacity, customer commitments, and budgetary constraints. This information helps the company make decisions ahead of time. This is where forecasting creates value.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Once the season begins, however, conditions may develop differently across product groups and locations. One region may experience colder weather earlier than expected. One product range may sell faster than forecast. A supplier may delay an important shipment. Another category may remain below the seasonal plan.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">The day-to-day questions then become:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li style=\"font-size:14px\">Which items face the greatest availability risk?<\/li>\n\n\n\n<li style=\"font-size:14px\">Which location should be replenished first?<\/li>\n\n\n\n<li style=\"font-size:14px\">Which delayed delivery will have the biggest effect on customer service?<\/li>\n\n\n\n<li style=\"font-size:14px\">Which products can continue to be replenished through the normal supply rhythm?<\/li>\n\n\n\n<li style=\"font-size:14px\">Which seasonal inventory positions need to be reviewed?<\/li>\n\n\n\n<li style=\"font-size:14px\">Where is stock becoming excessive compared with actual consumption?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">These are TOC inventory management questions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Forecasting helped the company prepare for winter. TOC helps it manage inventory flow throughout the winter season.<\/p>\n\n\n\n<p class=\"has-theme-primary-color has-text-color has-link-color wp-elements-15 wp-block-paragraph\" style=\"font-size:18px\">Forecasts should help plan exceptions, not create permanent noise<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">A common practical problem appears when known future events are added to a general daily forecast and remain in the system after the event has ended. This can keep target inventory levels artificially high and lead to excess stock.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">For this reason, such events should be clearly separated and managed as planned, time-bound exceptions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">For example, a planned promotion can include:<\/p>\n\n\n\n<ul style=\"font-size:14px\" class=\"wp-block-list\">\n<li>The products involved.<\/li>\n\n\n\n<li>The expected quantity or demand uplift.<\/li>\n\n\n\n<li>The affected locations.<\/li>\n\n\n\n<li>The planned start and end dates.<\/li>\n\n\n\n<li>The planned supply or capacity arrangement.<\/li>\n\n\n\n<li>The person responsible for reviewing the exception.<\/li>\n\n\n\n<li>The date when normal replenishment logic resumes.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">This allows the business to prepare in advance while keeping day-to-day inventory management connected to actual consumption.<\/p>\n\n\n\n<p class=\"has-theme-primary-color has-text-color has-link-color wp-elements-16 wp-block-paragraph\" style=\"font-size:18px\">What happens when the forecast and reality differ?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Mismatches between forecast and reality happen quite often. What is their value? They indicate the areas in which assumptions should be reconsidered.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">In the case when the demand is higher than forecast, the TOC approach allows identifying the priority of availability and necessary replenishment. It is up to the sales group to analyze the nature of demand changes: whether they are temporary, seasonal, for a certain customer, or will persist.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">When the demand is lower than the forecast, the TOC approach reveals the areas in which buffers are now too large compared to the demand.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">In both cases, TOC and forecasting have different responsibilities:<\/p>\n\n\n\n<ul style=\"font-size:14px\" class=\"wp-block-list\">\n<li>TOC manages the immediate operational response.<\/li>\n\n\n\n<li>Forecasting is reviewed to improve future preparation.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">This prevents every forecast deviation from becoming a reason to manually change daily order quantities for every item.<\/p>\n\n\n\n<p class=\"has-theme-primary-color has-text-color has-link-color wp-elements-17 wp-block-paragraph\" style=\"font-size:18px\">Inventory management with StockM<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\"><a href=\"https:\/\/www.stockm.eu\/\">StockM system<\/a> includes TOC Dynamic Buffer Management methodology to help companies manage their current inventory position through buffer-based priorities, replenishment recommendations, visibility of inventory and supply positions, and reduction of recurring shortages and excess stock.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Every day, inventory planners see a clear list of the tasks that should be addressed first. These include placing new supplier orders, reviewing products moving towards the red zone, checking late orders, analysing excess items, and deciding on the appropriate action.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">StockM is designed to make inventory management as efficient as possible and help employees focus on the areas where their attention creates the greatest value. Although StockM inventory management is based on TOC principles, forecasting can still be used to set initial parameters or plan an upcoming promotion or seasonal period.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">StockM clearly separates day-to-day inventory management from future planning. This structure allows companies to benefit from forecasting without making every daily inventory decision dependent on a forecast that may no longer reflect current demand and supply conditions.<\/p>\n\n\n\n<p class=\"has-theme-primary-color has-text-color has-link-color wp-elements-18 wp-block-paragraph\" style=\"font-size:18px\"><a>TOC for daily inventory management, forecasting for future preparation<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">Many sources present TOC and forecasting as two competing inventory management approaches. In many businesses, that perception is understandable because forecasting is widely used to manage both daily inventory decisions and future planning.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">However, companies often find that using forecasting as the main tool for day-to-day inventory control creates significant uncertainty and instability. This can lead to a familiar cycle: some products are consistently unavailable while others remain in excess.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">TOC addresses day-to-day uncertainty by managing inventory according to the current situation and recommending buffer changes based on actual demand. Buffer status makes it easier to identify the products and situations that require attention immediately, so inventory planners do not need to review every item or rely on guesswork.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" style=\"font-size:16px\">There are still situations where actual demand alone cannot provide enough information. Future planning, such as promotions, seasonal peaks, planned launches, and large projects, requires the company to use available historical data and business information to prepare for what may happen next.
