Demand forecasting models-Everything You Need to Know About Demand Forecasting - Supply Chain Link Blog - Arkieva

Demand Forecasting is the process in which historical sales data is used to develop an estimate of an expected forecast of customer demand. To businesses, Demand Forecasting provides an estimate of the amount of goods and services that its customers will purchase in the foreseeable future. Critical business assumptions like turnover, profit margins, cash flow, capital expenditure, risk assessment and mitigation plans, capacity planning, etc. Demand Forecasting can be broadly classified based on the level of detailing, time span considered and the scope of market considered. Some real-world practical examples of Demand Forecasting are — A leading car maker, refers to the last 12 months of actual sales of its cars at model, engine type, and color level; and based on the expected growth, forecasts the short-term demand for the next 12 month for purchase, production and inventory planning purposes.

It is occasionally true, of forecssting, that one can Demand forecasting models certain a new product will be enthusiastically accepted. His current interests center on strategic planning for new products and development of improved forecasting methods. Note the points where inventories are Demqnd or maintained in this manufacturing and distribution system—these are the pipeline Demand forecasting models, which exert important effects throughout the flow system and hence are of critical interest to the forecaster. If demand is affected by many variables, then it is called multi-variable demand function. Forecasts that morels sketch what the future will be like if a company makes no significant changes in tactics and strategy are usually not good enough for planning purposes. This method is quite simple and less expensive. A leading food manufacturing company refers to the last 24 Uc babe of actual sales of its highly Demandd products like soups and mashed potatoes. Some uncontrollable factors have the ability to influence consumer demand as well. Frequently, however, the market for a new product is weakly defined or few data are available, the product Demand forecasting models Dorothy xxx still fluid, and history seems irrelevant. The exercises undertaken in the survey method as shown in Figure are discussed as follows:.

These models provide information for making major strategic decisions and demand pattern data from long term data sets can help a company forecast for end of life products and new product introductions to a growing industry. Categories : Statistical forecasting Demand Supply chain management. Calculating demand Demand forecasting models accuracy is the process of determining the accuracy of forecasts made regarding customer demand for a product. In sum, then, the objective of the forecasting technique used here is to do the best possible job of sorting out trends and seasonalities. However, by and large, the manager will concentrate forecasting attention on these areas:. In the short term, the seasonal pattern of demand and the effect of tactical decisions on the customer demand are taken into consideration. In particular, when recent data seem to reflect sharp growth or decline in sales or Demand forecasting models other market anomaly, the forecaster should determine Demand forecasting models any special events occurred during the period under consideration—promotion, strikes, changes in the economy, and so Demand forecasting models. Demand can be forecasted using A Qualitative methods or B Quantitative methods as explained Free nudist movies videos Qualitative methods: The Delphi Technique: A panel of experts are appointed to produce a Demand Forecast.

However, it is not useful for forecasting new products. It should be applicable to data with a variety of characteristics. The output includes plots of the trend cycle and the growth rate, which can concurrently be received on graphic displays on a time-shared terminal. Group-Item Forecasts In some instances where statistical methods do not provide acceptable accuracy for individual items, one can obtain the desired accuracy by grouping items together, where this reduces the relative amount of randomness Hot rockabilly chicks the data. The matter is not so simple as it sounds, however.

Demand forecasting is the area of predictive analytics dedicated to understanding consumer demand for goods or services.

  • However, each industry and niche has its own demand patterns.
  • Demand forecasting is a field of predictive analytics [1] which tries to understand and predict customer demand to optimize supply decisions by corporate supply chain and business management.
  • An algorithm is a procedure or formula for solving a problem, based on conducting a sequence of finite operations or specified actions.
  • For wholesalers and distributors of durable goods products, inventory forecasting is especially important as it is the foundation upon which all company plans are built in terms of markets and revenue projections.

Predict your future product sales and inventory levels. Download now! But what is demand forecasting, you might ask?

Simply put, it refers to making estimations about future customer demand using historical data and other information. Proper demand forecasting gives businesses valuable information about their potential in their current market and other markets, so that managers can make informed decisions about pricing, business growth strategies, and market potential.

Without demand forecasting, businesses risk making poor decisions about their products and target markets — and ill-informed decisions can have far-reaching negative effects on inventory holding costs , customer satisfaction, supply chain management , and profitability. There are a number of reasons why demand forecasting is an important process for businesses:. In this instance, other information such as expert opinions, market research, and comparative analyses are used to form quantitative estimates about demand.

This approach is often used in areas like technology, where new products may be unprecedented, and customer interest is difficult to gauge ahead of time. When historical data is available for a product or product line and trends are clear, businesses tend to use the time series analysis approach to demand forecasting. A time series analysis is useful for identifying seasonal fluctuations in demand, cyclical patterns, and key sales trends.

As with time series analyses, historical data is key to creating a causal model forecast. While seasonality refers to variations in demand that occur during specific times on a periodic basis such as the holiday season , trends can occur at any time and signal an overall shift in behavior such as a specific product growing in popularity.

When it comes to demand forecasting, you should factor in estimates of trends and estimates of seasonality to accurately plan your inventory management strategy, marketing efforts, and operational processes.

Essentially, demand forecasting is a good way to anticipate what customers are going to want from your business in the future, so you can prepare inventory and resources to meet that demand. For businesses to have a truly agile and up-to-date data informed approach to decision-making, demand forecasting needs to happen in real time — and that means utilizing technology to do the hard work for you. In other words, you can know when to reorder stock and make data-informed business decisions without needing to do any of the forecasting manually.

That equals greater cost efficiency and time savings — two things that are integral to the success of any business. Start my free trial now. Are you looking for an easier way to manage and grow your business? Save time and money by signing up for a free trial of TradeGecko today!

One of the best techniques we know for analyzing historical data in depth to determine seasonals, present sales rate, and growth is the X Census Bureau Technique, which simultaneously removes seasonals from raw information and fits a trend-cycle line to the data. Trend projection requires a lot of reliable data about past performance. Such a model is an extension or combination of various Qualitative and Quantitative Methods of Demand Forecasting. For Corning Ware, where the levels of the distribution system are organized in a relatively straightforward way, we use statistical methods to forecast shipments and field information to forecast changes in shipment rates. The only difference will be the mathematical equation applied to the data.

Demand forecasting models

Demand forecasting models. How Algorithms Work In

For wholesalers and distributors of durable goods products, inventory forecasting is especially important as it is the foundation upon which all company plans are built in terms of markets and revenue projections.

Management would be a simple matter if business was not in a continual state of motion, the pace of which has quickened in recent years. Inventory forecasting models are critical elements of the forecasting process as accuracy can drastically influence business profitability.

It is becoming increasingly important and necessary for business to predict their future demand in terms of inventory availability, sales assumptions, costs and profits.

Assessing the actual value of future sales is crucial as it directly affects future carrying costs and profits, so the prediction of future sales is the logical starting point of all business planning, including inventory purchasing. There are 2 main inventory forecasting models to consider for enhancing inventory forecasting accuracy:. Depending on the industry and the unique businesses inventory turnover ratios, there are 2 different models for monitoring inventory and replenishment :.

Inventory planners need to evaluate and monitor both long-term and short-term influencers when it comes to demand forecasting. For instance in a short run forecast, seasonal demand patterns are of great importance to inventory planners. The third uses highly refined and specific information about relationships between system elements, and is powerful enough to take special events formally into account. As with time series analysis and projection techniques, the past is important to causal models.

We hope to give the executive insight into the potential of forecasting by showing how this problem is to be approached. Primarily, these are used when data are scarce—for example, when a product is first introduced into a market. They use human judgment and rating schemes to turn qualitative information into quantitative estimates. The objective here is to bring together in a logical, unbiased, and systematic way all information and judgments which relate to the factors being estimated.

Some of the techniques listed are not in reality a single method or model, but a whole family. Thus our statements may not accurately describe all the variations of a technique and should rather be interpreted as descriptive of the basic concept of each. A disclaimer about estimates in the chart is also in order. Estimates of costs are approximate, as are computation times, accuracy ratings, and ratings for turning-point identification.

The costs of some procedures depend on whether they are being used routinely or are set up for a single forecast; also, if weightings or seasonals have to be determined anew each time a forecast is made, costs increase significantly. Still, the figures we present may serve as general guidelines. The reader may find frequent reference to this gate-fold helpful for the remainder of the article.

Once they are known, various mathematical techniques can develop projections from them. The matter is not so simple as it sounds, however. It is usually difficult to make projections from raw data since the rates and trends are not immediately obvious; they are mixed up with seasonal variations, for example, and perhaps distorted by such factors as the effects of a large sales promotion campaign.

The raw data must be massaged before they are usable, and this is frequently done by time series analysis. Time series analysis helps to identify and explain:. That is, they do not separate trends from cycles. It is obvious from this description that all statistical techniques are based on the assumption that existing patterns will continue into the future.

For this same reason, these techniques ordinarily cannot predict when the rate of growth in a trend will change significantly—for example, when a period of slow growth in sales will suddenly change to a period of rapid decay. Such points are called turning points. They are naturally of the greatest consequence to the manager, and, as we shall see, the forecaster must use different tools from pure statistical techniques to predict when they will occur. When historical data are available and enough analysis has been performed to spell out explicitly the relationships between the factor to be forecast and other factors such as related businesses, economic forces, and socioeconomic factors , the forecaster often constructs a causal model.

It expresses mathematically the relevant causal relationships, and may include pipeline considerations i. The causal model takes into account everything known of the dynamics of the flow system and utilizes predictions of related events such as competitive actions, strikes, and promotions. If the data are available, the model generally includes factors for each location in the flow chart as illustrated in Exhibit II and connects these by equations to describe overall product flow.

If certain kinds of data are lacking, initially it may be necessary to make assumptions about some of the relationships and then track what is happening to determine if the assumptions are true. As the chart shows, causal models are by far the best for predicting turning points and preparing long-range forecasts. The forecasting techniques that provide these sets of information differ analogously.

Equally, different products may require different kinds of forecasting. Two CGW products that have been handled quite differently are the major glass components for color TV tubes, of which Corning is a prime supplier, and Corning Ware cookware, a proprietary consumer product line.

Many of the changes in shipment rates and in overall profitability are therefore due to actions taken by manufacturers themselves. Tactical decisions on promotions, specials, and pricing are usually at their discretion as well. Between these two examples, our discussion will embrace nearly the whole range of forecasting techniques. As necessary, however, we shall touch on other products and other forecasting methods. Forecasts that help to answer these long-range questions must necessarily have long horizons themselves.

A common objection to much long-range forecasting is that it is virtually impossible to predict with accuracy what will happen several years into the future. However, at the very least, the forecast and a measure of its accuracy enable the manager to know the risks in pursuing a selected strategy and in this knowledge to choose an appropriate strategy from those available.

Systematic market research is, of course, a mainstay in this area. But there are other tools as well, depending on the state of the market and the product concept. While there can be no direct data about a product that is still a gleam in the eye, information about its likely performance can be gathered in a number of ways, provided the market in which it is to be sold is a known entity. We call this product differences measurement. Specifically, it is often useful to project the S -shaped growth curves for the levels of income of different geographical regions.

When color TV bulbs were proposed as a product, CGW was able to identify the factors that would influence sales growth. In , we disaggregated the market for color television by income levels and geographical regions and compared these submarkets with the historical pattern of black-and-white TV market growth.

We justified this procedure by arguing that color TV represented an advance over black-and-white analogous to although less intense than the advance that black-and-white TV represented over radio. The analyses of black-and-white TV market growth also enabled us to estimate the variability to be expected—that is, the degree to which our projections would differ from actual as the result of economic and other factors.

The prices of black-and-white TV and other major household appliances in , consumer disposable income in , the prices of color TV and other appliances in , and consumer disposable income for were all profitably considered in developing our long-range forecast for color-TV penetration on a national basis.

The success patterns of black-and-white TV, then, provided insight into the likelihood of success and sales potential of color TV. Our predictions of consumer acceptance of Corning Ware cookware, on the other hand, were derived primarily from one expert source, a manager who thoroughly understood consumer preferences and the housewares market.

These predictions have been well borne out. This reinforces our belief that sales forecasts for a new product that will compete in an existing market are bound to be incomplete and uncertain unless one culls the best judgments of fully experienced personnel. Frequently, however, the market for a new product is weakly defined or few data are available, the product concept is still fluid, and history seems irrelevant. This is the case for gas turbines, electric and steam automobiles, modular housing, pollution measurement devices, and time-shared computer terminals.

At CGW, in several instances, we have used it to estimate demand for such new products, with success. Input-output analysis, combined with other techniques, can be extremely useful in projecting the future course of broad technologies and broad changes in the economy. The basic tools here are the input-output tables of U. Since a business or product line may represent only a small sector of an industry, it may be difficult to use the tables directly. However, a number of companies are disaggregating industries to evaluate their sales potential and to forecast changes in product mixes—the phasing out of old lines and introduction of others.

Other techniques, such as panel consensus and visionary forecasting, seem less effective to us, and we cannot evaluate them from our own experience. Significant profits depend on finding the right answers, and it is therefore economically feasible to expend relatively large amounts of effort and money on obtaining good forecasts, short-, medium-, and long-range.

For example, it is important to distinguish between sales to innovators, who will try anything new, and sales to imitators, who will buy a product only after it has been accepted by innovators, for it is the latter group that provides demand stability.

Many new products have initially appeared successful because of purchases by innovators, only to fail later in the stretch. Tracking the two groups means market research, possibly via opinion panels. A panel ought to contain both innovators and imitators, since innovators can teach one a lot about how to improve a product while imitators provide insight into the desires and expectations of the whole market.

The color TV set, for example, was introduced in , but did not gain acceptance from the majority of consumers until late Market research studies can naturally be useful, as we have indicated. Column 4 shows that total expenditures for appliances are relatively stable over periods of several years; hence, new appliances must compete with existing ones, especially during recessions note the figures for —, —, —, and — Certain special fluctuations in these figures are of special significance here.

Probably the acceptance of black-and-white TV as a major appliance in caused the ratio of all major household appliances to total consumer goods see column 5 to rise to 4. Our expectation in mid was that the introduction of color TV would induce a similar increase. Thus, although this product comparison did not provide us with an accurate or detailed forecast, it did place an upper bound on the future total sales we could expect.

The next step was to look at the cumulative penetration curve for black-and-white TVs in U. We assumed color-TV penetration would have a similar S -curve, but that it would take longer for color sets to penetrate the whole market that is, reach steady-state sales. At the same time, studies conducted in and showed significantly different penetration sales for color TV in various income groups, rates that were helpful to us in projecting the color-TV curve and tracking the accuracy of our projection.

With these data and assumptions, we forecast retail sales for the remainder of through mid see the dotted section of the lower curve in Exhibit V. The forecasts were accurate through but too high in the following three years, primarily because of declining general economic conditions and changing pricing policies. We should note that when we developed these forecasts and techniques, we recognized that additional techniques would be necessary at later times to maintain the accuracy that would be needed in subsequent periods.

These forecasts provided acceptable accuracy for the time they were made, however, since the major goal then was only to estimate the penetration rate and the ultimate, steady-state level of sales.

For the purposes of initial introduction into the markets, it may only be necessary to determine the minimum sales rate required for a product venture to meet corporate objectives. Analyses like input-output, historical trend, and technological forecasting can be used to estimate this minimum.

As we have seen, this date is a function of many factors: the existence of a distribution system, customer acceptance of or familiarity with the product concept, the need met by the product, significant events such as color network programming , and so on. As well as by reviewing the behavior of similar products, the date may be estimated through Delphi exercises or through rating and ranking schemes, whereby the factors important to customer acceptance are estimated, each competitor product is rated on each factor, and an overall score is tallied for the competitor against a score for the new product.

As we have said, it is usually difficult to forecast precisely when the turning point will occur; and, in our experience, the best accuracy that can be expected is within three months to two years of the actual time.

It is occasionally true, of course, that one can be certain a new product will be enthusiastically accepted. Market tests and initial customer reaction made it clear there would be a large market for Corning Ware cookware. Since the distribution system was already in existence, the time required for the line to reach rapid growth depended primarily on our ability to manufacture it.

When a product has entered rapid growth, on the other hand, there are generally sufficient data available to construct statistical and possibly even causal growth models although the latter will necessarily contain assumptions that must be verified later. We conducted frequent marketing studies as well. The growth rate for Corning Ware Cookware, as we explained, was limited primarily by our production capabilities; and hence the basic information to be predicted in that case was the date of leveling growth.

Because substantial inventories buffered information on consumer sales all along the line, good field data were lacking, which made this date difficult to estimate. While the ware-in-process demand in the pipeline has an S -curve like that of retail sales, it may lag or lead sales by several months, distorting the shape of the demand on the component supplier.

Exhibit VI shows the long-term trend of demand on a component supplier other than Corning as a function of distributor sales and distributor inventories. As one can see from this curve, supplier sales may grow relatively sharply for several months and peak before retail sales have leveled off. The implications of these curves for facilities planning and allocation are obvious. Exhibit VI Patterns for Color-TV Distributor Sales, Distributor Inventories, and Component Sales Note: Scales are different for component sales, distributor inventories, and distributor sales, with the patterns put on the same graph for illustrative purposes.

To estimate total demand on CGW production, we used a retail demand model and a pipeline simulation. The model incorporated penetration rates, mortality curves, and the like. We combined the data generated by the model with market-share data, data on glass losses, and other information to make up the corpus of inputs for the pipeline simulation.

The simulation output allowed us to apply projected curves like the ones shown in Exhibit VI to our own component-manufacturing planning. That is, simulation bypasses the need for analytical solution techniques and for mathematical duplication of a complex environment and allows experimentation. Simulation also informs us how the pipeline elements will behave and interact over time—knowledge that is very useful in forecasting, especially in constructing formal causal models at a later date.

Statistical methods provide a good short-term basis for estimating and checking the growth rate and signaling when turning points will occur. In late it appeared to us that the ware-in-process demand was increasing, since there was a consistent positive difference between actual TV bulb sales and forecasted bulb sales.

Conversations with product managers and other personnel indicated there might have been a significant change in pipeline activity; it appeared that rapid increases in retail demand were boosting glass requirements for ware-in-process, which could create a hump in the S -curve like the one illustrated in Exhibit VI. This humping provided additional profit for CGW in but had an adverse effect in We were able to predict this hump, but unfortunately we were unable to reduce or avoid it because the pipeline was not sufficiently under our control.

The inventories all along the pipeline also follow an S -curve as shown in Exhibit VI , a fact that creates and compounds two characteristic conditions in the pipeline as a whole: initial overfilling and subsequent shifts between too much and too little inventory at various points—a sequence of feast-and-famine conditions.

For example, the simpler distribution system for Corning Ware had an S -curve like the ones we have examined. When the retail sales slowed from rapid to normal growth, however, there were no early indications from shipment data that this crucial turning point had been reached. Data on distributor inventories gave us some warning that the pipeline was over filling, but the turning point at the retail level was still not identified quickly enough, as we have mentioned before, because of lack of good data at the level.

We now monitor field information regularly to identify significant changes, and adjust our shipment forecasts accordingly. For example, the color-TV forecasting model initially considered only total set penetrations at different income levels, without considering the way in which the sets were being used. Over time, it was easy to check these forecasts against actual volume of sales, and hence to check on the procedures by which we were generating them.

We also found we had to increase the number of factors in the simulation model—for instance, we had to expand the model to consider different sizes of bulbs—and this improved our overall accuracy and usefulness.

The preceding is only one approach that can be used in forecasting sales of new products that are in a rapid growth. Others have discussed different ones. It is possible that swings in demand and profit will occur because of changing economic conditions, new and competitive products, pipeline dynamics, and so on, and the manager will have to maintain the tracking activities and even introduce new ones.

However, by and large, the manager will concentrate forecasting attention on these areas:. The manager will also need a good tracking and warning system to identify significantly declining demand for the product but hopefully that is a long way off. To be sure, the manager will want margin and profit projection and long-range forecasts to assist planning at the corporate level. For Corning Ware, where the levels of the distribution system are organized in a relatively straightforward way, we use statistical methods to forecast shipments and field information to forecast changes in shipment rates.

We are now in the process of incorporating special information—marketing strategies, economic forecasts, and so on—directly into the shipment forecasts. This is leading us in the direction of a causal forecasting model. We find this true, for example, in estimating the demand for TV glass by size and customer. In general, however, at this point in the life cycle, sufficient time series data are available and enough causal relationships are known from direct experience and market studies so that the forecaster can indeed apply these two powerful sets of tools.

Historical data for at least the last several years should be available. The forecaster will use all of it, one way or another. We might mention a common criticism at this point. We think this point of view had little validity. In practice, we find, overall patterns tend to continue for a minimum of one or two quarters into the future, even when special conditions cause sales to fluctuate for one or two monthly periods in the immediate future. For short-term forecasting for one to three months ahead, the effects of such factors as general economic conditions are minimal, and do not cause radical shifts in demand patterns.

And because trends tend to change gradually rather than suddenly, statistical and other quantitative methods are excellent for short-term forecasting. Not directly related to product life-cycle forecasting, but still important to its success, are certain applications which we briefly mention here for those who are particularly interested.

While the X method and econometric or causal models are good for forecasting aggregated sales for a number of items, it is not economically feasible to use these techniques for controlling inventories of individual items. Some of the requirements that a forecasting technique for production and inventory control purposes must meet are these:. Adaptive forecasting also meets these criteria. There are a number of variations in the exponential smoothing and adaptive forecasting methods; however, all have the common characteristic at least in a descriptive sense that the new forecast equals the old forecast plus some fraction of the latest forecast error.

Virtually all the statistical techniques described in our discussion of the steady-state phase except the X should be categorized as special cases of the recently developed Box-Jenkins technique.

Until computational shortcuts can be developed, it will have limited use in the production and inventory control area. However, the Box-Jenkins has one very important feature not existing in the other statistical techniques: the ability to incorporate special information for example, price changes and economic data into the forecast. For example, the type and length of moving average used is determined by the variability and other characteristics of the data at hand. We expect that better computer methods will be developed in the near future to significantly reduce these costs.

In some instances where statistical methods do not provide acceptable accuracy for individual items, one can obtain the desired accuracy by grouping items together, where this reduces the relative amount of randomness in the data.

How to Choose the Right Forecasting Technique

Demand Forecasting is the process in which historical sales data is used to develop an estimate of an expected forecast of customer demand. To businesses, Demand Forecasting provides an estimate of the amount of goods and services that its customers will purchase in the foreseeable future.

Critical business assumptions like turnover, profit margins, cash flow, capital expenditure, risk assessment and mitigation plans, capacity planning, etc. Demand Forecasting can be broadly classified based on the level of detailing, time span considered and the scope of market considered.

Some real-world practical examples of Demand Forecasting are — A leading car maker, refers to the last 12 months of actual sales of its cars at model, engine type, and color level; and based on the expected growth, forecasts the short-term demand for the next 12 month for purchase, production and inventory planning purposes.

A leading food manufacturing company refers to the last 24 months of actual sales of its highly seasonal products like soups and mashed potatoes. An analysis is carried out at the flavor and packaging size level. Then based on the market potential, demand is forecasted for the next 12 to 24 months for sourcing of key ingredients like tomatoes, potatoes, etc. Demand Forecasting is the pivotal business process around which strategic and operational plans of a company are devised.

Based on the Demand Forecast, strategic and long-range plans of a business like budgeting, financial planning, sales and marketing plans, capacity planning, risk assessment and mitigation plans are formulated.

Short to medium term tactical plans like pre-building, make-to-stock, make-to-order, contract manufacturing, supply planning, network balancing, etc. Demand Forecasting also facilitates important management activities like decision making, performance evaluation, judicious allocation of resources in a constrained environment and business expansion planning.

Demand can be forecasted using A Qualitative methods or B Quantitative methods as explained below:. Objectives of Demand Forecasting include Financial planning, Pricing policy, Manufacturing policy, Sales, and Marketing planning, Capacity planning and expansion, Manpower planning and Capital expenditure.

Such a model is an extension or combination of various Qualitative and Quantitative Methods of Demand Forecasting. The task of developing a customized model is often iterative, highly detailed and expertise-driven and can be accomplished by implementing a suitable demand management software. Enjoyed this post? What is Demand Forecasting? Demand Forecasting types Demand Forecasting can be broadly classified based on the level of detailing, time span considered and the scope of market considered.

Outlined below are the major types of Demand Forecasting: Passive Demand Forecasting: Passive Demand Forecasting is carried out for stable businesses with very conservative growth plans. Simple extrapolations of historical data is carried out with minimal assumptions. This is a rare type of forecasting limited to small and local businesses.

Active Demand Forecasting: Active Demand Forecasting is carried out for scaling and diversifying businesses with aggressive growth plans in terms of marketing activities, product portfolio expansion and consideration of competitor activities and external economic environment.

Short-term Demand Forecasting: Short-term Demand Forecasting is carried out for a shorter term period of 3 months to 12 months. In the short term, the seasonal pattern of demand and the effect of tactical decisions on the customer demand are taken into consideration. Long-term Forecasting drives the business strategy planning, sales and marketing planning, financial planning, capacity planning, capital expenditure, etc.

External macro level Demand Forecasting: This type of Forecasting deals with the broader market movements which depend on the macroeconomic environment.

External Forecasting is carried out for evaluating the strategic objectives of a business like product portfolio expansion, entering new customer segments, technological disruptions, a paradigm shift in consumer behavior and risk mitigation strategies. This includes annual sales forecast, estimation of COGS, net profit margin, cash flow, etc.

Importance of Demand Forecasting Demand Forecasting is the pivotal business process around which strategic and operational plans of a company are devised. Demand can be forecasted using A Qualitative methods or B Quantitative methods as explained below: Qualitative methods: The Delphi Technique: A panel of experts are appointed to produce a Demand Forecast. Each expert is asked to generate a forecast of their assigned specific segment.

After the initial forecasting round, each expert reads out their forecast and in the process, each expert is influenced by other experts. A consequent forecast is again made by all experts and the process is repeated until all experts reach a near consensus scenario.

Each Salesperson evaluates their respective region and product categories and provides their individual customer demand. Market Research: In market research technique, customer-specific surveys are deployed to generate potential demand.

Such surveys are generally in the form of questionnaires that directly seeks personal, demographic, preference and economic information from end customers. Since this type of research is on a random sampling basis, care needs to be exercised in terms of the survey regions, locations, and demographics of the end customer. This type of method could be beneficial for products that have little to no demand history. Barometric technique: Barometric technique of Demand Forecasting is based on the principle of recording events in the present to predict the future.

In the Demand Forecasting process, this is accomplished by analyzing the statistical and economic indicators. Generally, forecasters deploy statistical analysis like Leading series, Concurrent series or Lagging series to generate the Demand Forecast. An equation is derived and fine-tuned to ensure a reliable historical representation. Finally, the projected values of the influencing variables are inserted into the equation to generate a forecast. The task of developing a customized model is often iterative, highly detailed and expertise-driven and can be accomplished by implementing a suitable demand management software Enjoyed this post?
