Trying to predict retail sales is a little like trying to predict the weather for a week or a day within a season. March winds and April showers may bring forth May flowers, but how stormy will it be? The summertime sun may shine brightly, but how hot will it be? The winter snows will fall, but will we get any blizzards? Can you really use last year’s weather information to predict what’s going to happen tomorrow? Not exactly, but you can know the average temperature to expect, and you can know from your experience how to be prepared on a given day for it to be warmer or cooler, rainy or snowy, windy or calm, even as you know the weather forecast won’t be perfect.
Understanding Time of Year Demand Patterns
Retailers face a tremendous challenge in trying to predict a multi-dimensional future. Which products will sell at which locations or be ordered online during which time frames are the core questions to answer with any forecast. Can you predict with certainty what will sell tomorrow? Certainly not, but you can learn from many prior experiences with categories of products or individual products in your markets and in your stores. You can be prepared to have the right product at the right store at the right time, not just to meet the average demand, but to account for reasonable localized variations for that product at that store at that time.
Retailers spend a significant amount of time, effort, and analysis to capture and track product and store performance throughout the selling cycle. Your goal is to learn from experience and plan for the future within the context of that history. Viewing that historical data alone is not sufficient. You can gather insights from other sources to understand characteristics of the consumers in the neighborhoods where the stores are located, what motivates customer purchasing behavior in-store or online, and what preferences they have, not only for products purchased in the past, but the attributes of new products they are likely to purchase in the future.
From this mix of history and insight, you can also gain an awareness of expected periods of time when you can anticipate demand to peak or to fall off for groups of products at various stores. Retailers frequently make use of product categories or grouping of products by common attributes or features by store groups or clusters to make high level planning, assortment, pricing, promotion, and other merchandising decisions. Many merchandising activities are arranged around the retail merchandising calendar that breaks a year into seasons, periods, and weeks. But what useful grouping of timeframes do you have to reflect what you have learned about customer sales across time?
Seasonal Profile Management
Seasonal profiles are used within forecasting techniques, representing historical and expected distinct selling patterns for a merchandising year. Often profiles suggest the actual calendar seasons of the year – Spring, Summer, Fall, and Winter. Frequently, profiles will reflect consumer purchasing influenced by other recurring activities such as gardening, hunting and fishing, football, baseball, or basketball seasons, school calendars, or holidays. With so many permutations of products and product groups, stores and store groups, and possible seasonal sales patterns groupings, it’s a challenge to gain benefits from the understanding of seasonal and recurring activities effect on future selling periods. It could be a set of difficult analytical and data management chores to define the most meaningful seasonal profiles, determine from which sets of products and locations those patterns can be derived, keep profiles up to date by learning from recent sales performance, and apply the right profile down to a SKU / store level during forecast calculations. Quantum Retail has developed a solution that eases these burdens for retailers.
Quantum Retail’s solution Q uses seasonal profiles to impact forecasts and inventory to account for how customer buying behavior changes over the course of the year. The profiles are derived for combinations of products and locations, often on the basis of some product or location characteristic other than the standard product hierarchy or store geographic hierarchy. For example, stores might be grouped by size or proximity to a competitor and products grouped by price range or brand rather than (or in addition to) by product hierarchy. Attributes for a known and planned seasonal timeframe, such as spring gardening or fall deer hunting might be used.
Influences on SKU’s and Store Performance
Rather than relying on a single profile updated and assigned by users at irregular intervals at a chosen level of product and store groupings, Q automatically makes use of multiple source levels of profiling information. Q evaluates additional higher level product and location groupings when applying a seasonal profile’s pattern to determine weekly demand. By evaluating the SKU / store in relation to relevant combinations such as SKU / store cluster, class / store or store / season code, Q dynamically finds the most appropriate indicator of expected future behavior.
The sets of source levels defined by the product and location levels to use and the escalation path of levels to evaluate are established as part of the Q implementation project and do not need to be maintained by users during production usage. Quantum Retail delivers the expertise and the science to make sure profiles use the right attributes that really have an effect on performance and not just preconceived groupings or aggregates with coincidental correlations. Q establishes the appropriate number of profiles and reasonable thresholds for scoring the fit of patterns to be deployed.
Seasonal Profiles Are an Integrated Component of Q
Profile weekly indices are updated automatically by Q continuously with true demand that accounts for lost sales due to out of stock situations in order to learn from and make use of recent activity. Other solutions in the market rely on separate modules for building and importing profiles on an infrequent basis based only on sales or shipments, resulting in profiles that are inaccurate and out of date.
Seasonality administration features provide a seasonal override ability to adjust the seasonal indices or ‘shift’ the seasonality of a given week. This shift functionality is useful in cases such as when holidays occur on different dates each year and the user wants to capture the fluctuation in sales over the holiday period on the new date in the current year (for example Easter). Seasonal profiles are aware of lift during promotional events and interact with Q Event Management features to accurately reflect lift in forecasts due to annual or one-time promotions.
Q learns and puts to use its knowledge about the impact of seasons and events at the most detailed level, by SKU and by store, but within the context of the behavior of similar products and similar selling locations and channels. That means that forecasts for re-orderable products will be more dynamic and more accurate. Q also applies that knowledge to make sure new products consider the correct seasonal influence in their introductory period and throughout their lifecycle, no matter how short it may be.
Profiles convey the shape of future demand and Q applies its understanding of product and location behavior to calculate the quantification and trending of demand. The nature of forecasting is that the result is a prediction of the future based upon assumptions of the past, subject to the uncertainty of unforeseen events. Q considers other metrics when allocating and replenishing to stores, such as sales variability and the predicted distribution and frequency of sales, which may play an even larger role than the forecast. Q makes intelligent decisions that guide recommendations whether or not to send case pack quantities to meet a low volume of forecast demand. Executed properly, considering these variables can compensate for inaccuracies in a forecast. Each capability of Q contributes to the overall effectiveness of the solution.
A Holistic Approach to Inventory Optimization
With the approach that Q takes to manage and apply seasonal profiles as a factor in its forecasts, the benefits are numerous. Q forecasts demand and calculates the inventory and orders needed to meet an objective rather than just trying to forecast sales. A solid forecast is a significant input into decisions on how to deploy inventory to manage selling at full price while minimizing markdowns or out of stocks.
Q provides several innovative yet practical approaches to building the components of the forecast to improve understanding of the past to model known likely influences on future performance. Q makes the use of seasonal profiles understandable for users without burying them in the complexity of the statistics and the algorithms that underlie the power that profiles provide them.
Those who follow the weather closely to help with their gardening hobby or farming industry can turn to the Old Farmer’s Almanac for useful short and long range weather forecasts as inputs to plan their planting, tending, and weeding. They can also find great tips on seed ordering, pest control, and other plant care ideas customized to their zip code. All that knowledge can help them optimize their harvest. Similarly, retailers can make use of seasonal profiles to get a read on demand and then employ the other holistic capabilities of Q to optimize their returns on inventory investments.
