• the present invention relates to a system and method for assessing a proposed promotion scheme.
• the present invention pertains to a system and method for assessing the promotion scheme in view of desired business goals such as increasing sales of particular products to a particular group of consumers, as well as suggesting improved promotion schemes to better achieve these business goals.
• Businesses commonly use promotional schemes to improve sales volumes and profits. For instance, a business may adjust prices as needed to encourage sales of particular products. Likewise, businesses may specially present or advertise their products to increase consumer awareness and demand. To generate incremental revenue or expand market share, companies spend billions of dollars annually in promotional discounts, rebates, cash incentives, coupons, and subsidized financing. Because of the variety of promotions in play at any one time, the complexity of the market, and an inadequate understanding of customer response, few companies are able to accurately predict the overall effectiveness of their promotional spending. The user making promotion decisions is faced with the challenge of how to best target promotional spending to achieve corporate goals at the lowest cost. To make this decision, the user needs to accurately forecast how a proposed promotion will affect revenues, profits, and sales volumes for each product.
• the user needs to calculate how much each promotion will reduce on-hand inventory while minimizing cross-product and cross-segment dilution.
• the user further needs to predict how different market segments will react to different types of promotions.
• the user also need to determine which combination of promotions will produce the highest return on expenditure while meeting sales, margin, and market share targets.
• the present invention provides a promotion pricing system and a related model for producing a value evaluation and recommendation for promotion on a targeted product so as to analyze, evaluate, improve, and design promotions to meet a user's need.

• the promotion pricing system of the present invention is general enough to provide price evaluations and recommendations with varying degrees of available data. While the ideal client for the system would maintain data on lost customers, competitor prices, industry availability and the like, most clients will have data on only a subset of the potential drivers of market response. In this way, the system enables the user to obtain valuable insight from the evaluation of a promotion program even with a minimum amount of input data and then increasing that value through increased forecasting accuracy and accurate evaluation as new and/or existing data is integrated.
• the promotion pricing system of the present invention enables the user to determine the impact of proposed promotions before committing to the promotion. Using historical data and statistically derived market response models, the promotion pricing system tests promotional scenarios and forecasts the results. The user can then determine how much each proposed promotion will affect revenues, profits, and sales volumes; how much each promotion will reduce on-hand inventory, how different customer segments will respond to different promotions, and which combination of promotions will generate the highest return on your promotional expenditures. In one embodiment, the promotion pricing system can simultaneously consider cannibalization effects of the promotion on other products or channels, allowing the user to maximize overall revenue growth.
• the user may develop and target promotions for each product, customer segment, and distribution channel.
• the promotion system further helps the user determine the best allocation of promotion and incentive dollars to meet your goals at the lowest possible expenditure. In this way, the promotion system and method of the present invention can produce substantial additional profit per year.
• the promotion system of the present invention tracks its progress, generates performance alerts when user-defined parameters are exceeded, and quickly pinpoints problems. Meanwhile, results are fed back into the system to help fine-tune future campaigns.
• the promotion system of the present invention allows a business to better understanding customer price sensitivity and to acquiring new customers at the least cost while retaining existing customers.
• the system further helps managing product or service lifecycles by suggesting promotions to encourage the sale of older inventory.
• the promotion system further acts to minimize product cannibalization and to address sales shortfalls.

• Product information is part of the base data required by the promotion pricing system 100.
• the product information consists of basic product information on pricing, costs, inventory and product hierarchies.
• account information provides account or customer profile information. This data is used to micro-segment the market and target different customer profiles with customized promotions.

Information on outbound channels is used to model marketing channel-specific cost distinctions and response variations. Overall, product, account, and channel information form the base data for the promotion pricing system 100. Purchase, or sales order, data drives the analysis of the promotion pricing system.
• Sales order information answers the question of "who bought what at what price when and how," where the "who” identifies the customer segment or profile of the customer; the "what" the set of products or services on offer; the “price” the pricing information associated with the sale, including any promotion information if relevant, and the "when” the timing of the purchase; and the how the channel or medium used for the sales transaction.
• both the user's own sales order and competitive sales order information is available for the promotion pricing system 100 to model competitive factors.
• the promotion pricing system 100 analyzes a promotion scheme and produces several outputs, including promotion effectiveness and market response, price elasticity information, and cannibalization/dilution details. In determining price elasticity, the promotion pricing system 100 may generate both the user's elasticity and cross-elasticity of other products, sales channels or incentive types on market response. The resolution of the forecasts depends on the quantity and quality of sales order and competitive data available. If individual product forecasts cannot be reliably generated, elasticity at an aggregate level (or product segment group) is generated by the promotion pricing system 100.
• the promotion pricing system 100 can compute expected lifts (i.e., sales increases) for a given promotion program in terms of quantity revenue, margin, or other industry-specific metrics. These estimates are generated at the level product, incentive type, sales channel, and marketing channel levels. The promotion pricing system 100 may then use cross-elasticity determinations to compute cannibalization or dilution effects on a given product or sales channel from competing or surrogate products and sales channels.
• Another functionality of the promotions system 100 is mark-down optimization.
• a retailer may receive shipments of excess inventory to their stores. The retailer knows how much of this inventory is normally sold within a given period of time given historical information and general business knowledge. However, they do not know the optimal discount to set to achieve the objective of selling that inventory within the specified time period. In other words, the user does not want to over discount a product.
• Promotions System 100 can solve this type of problem given certain inputs such as the target product, the total initial inventory for that product, and the amount of inventory that is to be sold for a given period. Promotions System 100 would then compute that discount which maximizes profit while clearing pre-identified excess inventory during the specified period.
• the promotions system may also perform strategic objectives analyses in assessing and achieving strategic corporate objectives a quarterly revenue target does not know if 1) is obtainable, and 2) how strategically she should approach achieving this objective using promotional incentives.
• Promotions System 100 can solve this problem by identifying 1) if the revenue target is feasible, and 2) if the target is feasible, what promotional incentive level will maximize profitability given this constraint.
• the PSM 200 defines the products in the market model created and analyzed by promotion pricing system 100. Specifically, the PSM 200 creates and organizes a list of related products.

The user may input this data (Step 220), or the PSM 200 may collect data from a list of products, step 230. For instance, the PSM 200 may download data from a database containing product catalog information or may employ known data collection and mining techniques such as automated XML data crawling applications.

• the promotion pricing system 100 operates under the general assumption that transactions are independent events that differ only by promotional efforts. These assumptions become increasingly less likely with smaller sets of data and suppliers.
• the CUSM 300 defines and categorizes the consumers of the products specified in by the PSM 200 in the product segmentation method 210.

• the CUSM 300 may further determine cross impacts between customer segments, step 360.
• the CUSM then keeps only the customer segmentations without cross impact between different segments, step 370.
• the CUSM 300 only looks to customer categories in which sales are independent events to avoid co variance terms in the mathematical evaluation of the market model created by the promotion pricing system 100.

Specifically, the DAM 500 may employ the data aggregation technique 510 depicted in FIG. 5. In step 520, the DAM 500 may separate data by customer segments. The separation may be automated or specified by the user. The DAM 500 may then determine a time interval at which to aggregate transaction volume data, step 530, on the basis of the number of time period needed to estimate parameters, the incentive offer and price variation cycle, and data collection frequency.

• Possible constraints include directionality constraints to enforce the assumption that a promotion scheme to should only positively effect product utility. Another possible constraint is to assume equal cross impact, thereby assuming that increase in sales volumes of market share are equally taken from other competitors, thereby simplifying the promotion assessment calculations.
• Another set of constraints relate to the incrementality, or the minimal intervals between usable values for the variables in the calibration and assessment. For instance, rounding the values for a variable may decrease accuracy but decreases the computational accuracy. Application of constraints may restrict regular significance test of estimated parameters, but the calibration process will provide adjusted R 2 to evaluate model fitness.

• COSM determines indirect promotion costs caused by the promotion scheme, step 1030. h particular, the COSM 1000 looks to, for example, the increased costs per unit associated with increased sales volume or share from the promotion. The COSM 1000 next determines the direct costs for the promotional scheme, step 1040. For instance, the COSM 1000 may determine incentive costs, offer channel cost, customer segment cost, order channel cost, etc. The COSM 1000 then sums the indirect and direct promotion scheme costs to determine a total cost.
• the OM 1100 can provide the answer to this question. Specifically, the OM 1100 will identify the optimal discount for each product (which generates the highest profitability) and rank products by profitability (given the recommended incentive). To guide the operation of the OM 1100, the user can establish business constraints to better reflect the needs of their business. For example, in the set fixed incentive levels, the user can identify an incentive level that should apply for any selected products or segments (i.e., all menswear should be discounted at 15%). In equality constraints on incentive levels, the user can specify that the discount for dress slacks should always be equal to the discount for dress shoes.
• Min / Max constraints on incentive levels the user can set maximum discount level (i.e., max discount of 50% assuring that the effective price of the product remains above that of lesser product lines), or minimum discount level (i.e., min discount level should remain above 6% to assure customer satisfaction and ease of communication).
• Min / Max constraints on margin allows the user to assure that the recommended discount level will not erode the objective per unit margins for a product (i.e., the margin for dress slacks must remain above 4%). Minimums can also be set (i.e., we must achieve at least a 10% margin on the sale of dress shirts). Similarly, set fixed margins allows a target margin to be established (i.e., all products within the casual wear product line must have a margin of 14%)).
• Min / Max incentive budget the user may specify a total "Incentive Budget" for a given time period (i.e., the total amount of cash back incentives should not exceed $800,000 for the next fiscal year, or the total dollar amount of cumulative discounts must not exceed $10,000).
• Inventory constraint allows the user to specify an inventory amount to prevent product shortages resulting from a sale (i.e., for a summer promotion, users only have 20,000 t-shirts available, and therefore, should set the discount level to maximize profitability for this number of units).

• the first step 1120 is to define an offer template. This generally consists of product/sales channel combinations, target customer segment, target incentive type and a time period. These may be defined according to previously defined methods, 210, 310, 410, and 510.
• An offer is made to a list of choices, where a choice is a combination of customer segment, product, and channel. For each choice, there is an incentive type (e.g. cashback, discount), and an incentive level (e.g. $20 off, 5% off).
• an incentive type e.g. cashback, discount
• an incentive level e.g. $20 off, 5% off.
• An offer template has the same form as an offer, with the following exception.
• An offer has associated incentive levels (e.g. level of discount, APR). For example, printer at 20%> off, computer at $100 off (assuming "printer” and "computer” are choices).
• some of the incentive levels that take on real values may be set to be NARIABLE. So, for example, printer at NARIABLE % off, computer at $100 off might be part of an offer template.
• Each offer template has instances associated with it. For example, printer at NARIABLE % off, computer at $100 off would have, as an instance, printer at 20%> off, computer at $100 off. h step 1130, the user specifies business rules/constraints.
• Incentive constraints apply at the group level.
• a group is a set of product / channel combinations that have been selected together by the user.
• incentive constraints there are several allowable types of incentive constraints, including: - Set fixed incentive levels. The user can set the incentive level to be a certain fixed amount (e.g. 7%) for all choices in the group. Equality constraints on incentive levels. The user can specify that all the incentive levels must be the same for all choices within the group. If this is not the case, then the incentive levels can vary independently. - Min / Max constraints on incentive levels.
• the user can specify that all the incentive levels within the group lie between specified min and max values.
• the user may specify a min or a max or both.
• Set fixed margins. Margin for a choice is defined as (List Price - Discount Amount - Cost) / (Cost).
• the user can specify that all margins within the group must be a certain amount (e.g. 8%) Min / Max constraints on margin.
• the user can specify that all the margins within the group lie between specified min and max values.
• the user may specify a min or a max or both.
• the system may set equality constraints on incentive levels within the group. Financial constraints (min / max incentive budget) apply at the global level.
• Incentive budget is the sum of cost of discount * volume across all product/channel combinations that are a part of the promotion.
• volume constraints (min / max volume, inventory) apply at a product level. These constraints apply only to product / sales channel combinations that are a part of the promotion. For example, suppose the user has selected "Blue Shirts/San Francisco”, “Blue Shirts/San Jose” and “Blue Shirts/L.A.” to be in the promotion, where "Blue Shirts” is a product. Then the user could impose a volume constraint on the sales of Blue Shirts. This would be applied to the sum of volumes, Nol(Blue Shirts/San Francisco) + Nol(Blue Shirts/San Jose) + Nol(Blue Shirts/L.A.) .
• optimization subject to inventory constraints is similar to unconstrained optimization but user could add constraints saying that demand generated should not exceed user-specified amounts (e.g. amount of inventory available). Alternatively, the user may optimize subject to business rules. Using incentive groups, the user can ensure that incentives are constant across a product category. Using constraints, the user can operate within a fixed marketing budget, and/or ensure that incentives do not vary too greatly from what is currently in place. In step 1140, the OM 1100 determines the optimal offer. Specifically, the OM
• the OM 1100 aims to solve (or approximately solve) the problem of considering all the offers that are instances of this offer template. The OM 1100 further considers the subset of these that satisfy the constraints. Each such offer will have an associated profit, and the OM 1100 finds the one that gives the largest profit and uses this a the optimal offer.
• the OM 1100 generally produces exact values for example, it may return that an optimal discount is 28.47%) off. The user can always use the optimized program as a guide and round values. Optionally, the OM 1100 may restrict optimization to consider only rounded promotions, h the instant example, the OM 1100 may compare the profitability of a 28%> discount with profits from 29%> discounts.

• the alert method 1310 is depicted in FIG. 13. Specifically, pre-defined logical expressions with threshold parameters need to be specified and updated by user step 1320. Baseline value refers to the value against which actual current value is compared. It varies depending on the alert type and is defined during step 1320. Various levels of alert severity may be defined in step 1320. The severity relates the degree of deviation from a baseline value to an actual value. The user needs to specify thresholds against which comparison is made, based on business domain knowledge and practice, and then input them into the appropriate data table.
• a severe alert for the actual vs. forecast could be generated if actual sales falls 2000 units or more short of forecast; similarly, a medium alert for the same type would be generated if actual sales falls 1000 to 2000 units short of forecast; and so on.

• the truck finance and the truck lease drivers are the price paid by the customer per month, so by construction they will never be null. If the Manufacturer decides not to give any cash rebate for its Truck (no incentives for cash back), the driver price still won't be null for mathematical purposes because at some point in the process of calculating the utility of Truck, the log of the drivers will need to be calculated and therefore, the drivers cannot be null.
