This patent application is related to a co-pending U.S. patent application Ser. No. 10/869,904, entitled “System and Method for Offer Targeting”, naming as first-inventor “Adam M. Levine,” filed Jun. 18, 2004, which is hereby incorporated by reference herein in its entirety.
The present invention relates generally to business communication and marketing. More particularly the present invention relates to a system and method for offer management.
A financial company typically mails statements to its credit card members or banking customers on a monthly basis. The financial company may also frequently mail credit cards or banking cards to the customers for re-issues or replacements. In addition, the company may occasionally send letters to current or potential customers for various purposes. Millions of mail pieces are produced and delivered every month for these purposes. Though a costly process, mailing of the statements, cards and letters creates a valuable opportunity for the company and its partners to promote products and services to the customers. These mail pieces are usually guaranteed to reach a large number of families or individuals and are much more likely to receive attention than other types of mass mailings. Companies have long been taking advantage of this communication channel by including advertisements and solicitations in the outgoing statements or letters. These advertisements or solicitations or the like (hereinafter collectively referred to as “offers”) may take the form of a message, an insert, a billhead, a convenience check, an inner envelope or an outer envelope, for example. An offer typically describes a specific promotional program (e.g., one related to a financial or insurance product) that is offered by a business entity and is usually targeted at a specific group of customers.
It is a demanding task to manage offers and to incorporate them into outgoing mail pieces. For any given month, a large financial company may typically target hundreds of offers at millions of customers based on complex business rules. These offers need to be properly created together with associated rules, matched to appropriate accounts, produced on a variety of paper stocks, and inserted into outgoing mail pieces. This same or similar process is typically repeated several times (“cycles”) each month. The large volumes of mail pieces require considerable investment of resources, the successful return of which depends heavily on the accuracy, efficiency and consistency in the offer management process.
A number of problems and drawbacks exist in traditional solutions of offer management. In general, there has not been a streamlined end-to-end process for offer management. Existing solutions typically fail to integrate the various offer management steps, such as offer and rule creation, offer prioritization, rule optimization, weight management, insert production and inventory management, into a coherent cycle. As a result, there is usually a lack of coordination among the offer management steps as well as between the mailing cycles. For example, it is not uncommon for prior art systems to encounter overages (i.e., excessive inventory for a particular offer) or unexpected stock-outs (i.e., unavailable inventory for a particular offer), both of which could be costly.
Other problems and drawbacks also exist.
In view of the foregoing, it would be desirable to provide a solution for offer management which overcomes the above-described deficiencies and shortcomings.
One embodiment of the present invention comprises a method for offer management. The method comprises: providing a plurality of offers and a plurality of business rules, wherein each of the plurality of offers is to be targeted at a predetermined number of accounts selected from a plurality of accounts based on the plurality of business rules; prioritizing the plurality of offers; grouping the plurality of accounts based on their qualification for each of the plurality of offers in accordance with the plurality of business rules; optimizing the plurality of business rules based at least in part on the prioritization of the plurality of offers and the grouping of the plurality of accounts, such that each of the plurality of offers is associated with at least the predetermined number of accounts; imposing a volume limit or weight limit for offers assigned to each of the plurality of accounts; incorporating the plurality of offers into communications associated with the plurality of accounts based at least in part on the plurality of optimized business rules and the volume limit or weight limit; and managing production of the communications based on at least one simulation, wherein the at least one simulation is performed based on data associated with the plurality of offers, the plurality of business rules and the plurality of accounts.

The system comprises: at least one user interface for entering and modifying a plurality of offers and a plurality of business rules, wherein each of the plurality of offers is to be targeted at a predetermined number of accounts selected from a plurality of accounts based on the plurality of business rules; storage means for storing and managing the plurality of offers, the plurality of business rules and the plurality of accounts; and processor means for: prioritizing the plurality of offers, grouping the plurality of accounts based on their qualification for each of the plurality of offers in accordance with the plurality of business rules, optimizing the plurality of business rules based at least in part on the prioritization of the plurality of offers and the grouping of the plurality of accounts, such that each of the plurality of offers is associated with at least the predetermined number of accounts, imposing a volume limit or weight limit for offers assigned to each of the plurality of accounts, incorporating the plurality of offers into communications associated with the plurality of accounts based at least in part on the plurality of optimized business rules and the volume limit or weight limit, and managing production of the communications based on at least one simulation, wherein the at least one simulation is performed based on data associated with the plurality of offers, the plurality of business rules and the plurality of accounts.
Yet another embodiment of the present invention comprises a method for offer management. The method comprises: providing a plurality of offers for incorporation into statement letters associated with a plurality of accounts, wherein the incorporation of the plurality of offers is based on a plurality of business rules; and simulating a final composition of the statement letters based at least in part on a prioritization of the plurality of offers, associations of the plurality of offers with the plurality of accounts, and layout, graphics and inventory weight associated with one or more sub-components of the statement letters.
Still another embodiment of the present invention comprises computer readable medium having code for causing at least one processor to perform offer management. The computer readable medium comprises: code adapted to provide a plurality of offers and a plurality of business rules, wherein each of the plurality of offers is to be targeted at a predetermined number of accounts selected from a plurality of accounts based on the plurality of business rules; code adapted to prioritize the plurality of offers; code adapted to group the plurality of accounts based on their qualification for each of the plurality of offers in accordance with the plurality of business rules; code adapted to optimize the plurality of business rules based at least in part on the prioritization of the plurality of offers and the grouping of the plurality of accounts, such that each of the plurality of offers is associated with at least the predetermined number of accounts; code adapted to impose a volume limit or weight limit for offers assigned to each of the plurality of accounts; code adapted to incorporate the plurality of offers into communications associated with the plurality of accounts based at least in part on the plurality of optimized business rules and the volume limit or weight limit; and code adapted to manage production of the communications based on at least one simulation, wherein the at least one simulation is performed based on data associated with the plurality of offers, the plurality of business rules and the plurality of accounts.
Additional features and advantages of the invention will be set forth in the description that follows, and in part will be apparent from the description and drawings, or may be learned by practice of the invention. The objects and other advantages of the invention will be realized and attained by the system and methods, particularly pointed out in the written description and claims hereof as well as the appended drawings.
The purpose and advantages of the present invention will be apparent to those of skill in the art from the following detailed description in conjunction with the appended drawings in which like reference characters are used to indicate like elements, and in which:
Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings. For illustration purposes, embodiments of the invention are described in the context of a financial company managing offers to be targeted at its customers through the statement channel (e.g., monthly mailing of credit card statements or banking statements). It should be appreciated by those skilled in the art that the exemplary system and method as described herein is applicable or adaptable to other communication channels (e.g., E-mails, plastics, letters, telemarketing scripts and the like) through which individualized or customized information, such as messages, advertisements, proposals, solicitations and the like, may be selectively delivered.

In step 100, account managers may utilize an offer entry system (OES) to add, modify, delete or copy offer items and the related business rules. The account managers may be marketing and/or relationship personnel who are each in charge of one or more groups of customer accounts. The offer entry system may be a web-based application with a graphical user interface (GUI). The offer items may include information of financial products and services, insurance products, related programs, and compliance notifications, for example. The offer items may be associated with a number of business rules that govern the targeting of the offer items to customer populations. For example, the rules may specify qualification criteria for an account to receive specific offers, the number of accounts that each offer can target, variation of offer terms or pricing structures based on account characteristics, and the number of offers each account may receive. Both the offers and business rules may be newly created or modified based on past entries. The offers and rules may be on a partner level, a portfolio level, an individual account level or a combination thereof. For example, customer accounts that are associated with a particular business partner may be grouped accordingly. A portfolio typically includes one or more partner groups that share an association with a common business program. For illustration purposes, a plurality of accounts that belong to either a partner group or a portfolio will be hereinafter referred to collectively as a “group.” A group may be identified with an account organization code (AOC) and an individual account may be identified with an account reference number (ARN). Offers may be targeted at an entire group without concerning characteristics of individual accounts within the group, for example. Or offers may be targeted at individual accounts regardless of which groups they belong to. The offer entry system may have data links to a number of data sources such as offer management files, list management files and a content management database. The offer entry system may also facilitate legal users to review and approve the offers for legal compliance. Super users or the statement team may access the offer entry system to process and audit offers.
In step 102, all offers for a statement month may be prioritized. A web-based application with a GUI may be utilized for offer prioritization. The prioritization application may provide the ability to execute the prioritization algorithm, adjust offer rankings and maintain prioritization rules. The priority rankings of the offers are typically based on a variety of factors, such as the offer category, partner or contractual obligations and profit potentials for each offer. For example, the offers may be categorized as mandatory or optional. The mandatory offers typically have higher priorities than optional ones. For another example, an offer with a historically better response rate (thus a greater profit potential) may have a higher priority than offers with lower response rates. In general, an offer may be assigned a priority ranking based on the extent that it comports with the overall strategic goals and objectives of the business organization. According to one embodiment of the invention, a business rules prioritization application may be run prior to the statement month to prioritize all the offers for that month. It is also possible to update the list of offers during the statement month and re-prioritize the offers accordingly.
According to an embodiment, historic account data may be used in measuring the effectiveness of statement offers. For example, it may be desirable to track the change of financial behaviors for an account before and after the insertion of a statement offer. One exemplary financial behavior worth monitoring is an account's outstanding balance B. In a scenario where only one offer is included in a statement, the fractional change in an account's outstanding balance during and after the insertion of the offer may be
where t is the month during which the offer X is included in the statement and It represent an offer set for month t. Similarly, the fractional change in the outstanding balance when no offer is included may be
where φ represents an empty set of offers. When equations (1) and (2) are averaged over the set of accounts that have received offer X in month t, a fractional change in these accounts' outstanding balance due to offer X may be estimated. To compare the effectiveness of two offers X1 and X2, a statistical test of significance may be performed on the estimates of βt(X1) and βt(X2), where standard hypothesis testing methods may be applied. Alternatively, the effectiveness may be measured by a logarithm of the ratio between the outstanding amounts in the months during and after the statement is mailed:
Depending on the range of values considered, sometimes it may be more desirable to calculate a logarithmic change than a fractional change. For illustrative purposes, however, only fractional changes will be described hereinafter.
Sometimes, the effect of an offer Q may last for a few months. In that case, the outstanding balance may be averaged for a time window subsequent to the insertion of offer Q, i.e.,
where K is the length of measurement window, t<s≦K, and it is assumed that either the same offer Q or nothing is included in the rest of the measurement window. Equation (4) only uses the outstanding balance B(t) as a basis for comparison, which may be subject to high variability due to inherent randomness of the accounts' financial behavior. Thus, sometimes it may be desirable to use a larger base window of K′ months. The fractional change is then
where t−K′+1≦s′<t<s≦K.
In practice, each account often receives multiple offers. In order to determine the relative effectiveness of two offers, it may be beneficial to align those accounts whose offers differ only by the two in question. For example, to compare two offers X1 and X2, where either of them is accompanied by other offers Y1, Y2, . . . , the fractional changes in outstanding balance may be
Statistical test of significance can be performed on the estimates of βt(X1) and βt(X2) over those accounts that have received the offer sets {X1, Y1, Y2 . . . } and {X2, Y1, Y2 . . . } respectively.
According to embodiments of the present invention, it may be desirable to set up a test and control environment to measure incremental effects of a particular offer. For example, the two fractional changes, βt(X) and βt(φ), may be calculated from two statistically identical populations before being compared. The population associated with βt(X) may be called a treatment group, and the population associated with βt(φ) may be called a control group. Both groups may be selected such that a decision to include a particular offer equally applies to both of them, only that the offer is intentionally suppressed for the control group. When two offers X1 and X2 are to be compared, the control group may be selected to serve as a common platform for the testing of two different offers. Population sizes for all treatment groups and control groups are usually large enough so that statistical inferences may be drawn from the test results.
According to one embodiment of the present invention, a predictive model may be created for the statement offers. Assume that Xi is an indicator variable that satisfies the following equation:
A predictive model may be a linear combination of all indictor variables:
Z=F(X1, X2 . . . , XN; α1, α2, . . . , αN) (9)
where N is a total number of offers, Z is a desired response variable, F( ) is the choice of modeling function, and {α1, α2, . . . , αN} is a finite set of modeling coefficients. In a simplest case,
Z=α0+α1X1+α2X2+ . . . +αNXN+ε (10)
which makes F( ) a linear model with an additional coefficient α0 (ε represents modeling error). Then, standard regression techniques may be applied to determine these coefficients.

In step 106, a rule optimization algorithm may be run. One goal of the rule optimization algorithm is to assign the offers to selected qualified groups (or accounts) based on the offer rankings and the grouping generated in the preceding steps, such that each offer hits its requested volume of accounts. When an offer is entered for a marketing campaign, there is typically a request for the offer to be targeted at a predetermined number of accounts. Such request may be fulfilled in this rule optimization step. The offers may be assigned to their qualified groups (or accounts) in the order of offer rankings. At the same time, an offer counter may be maintained for each group (or account) to keep track of the number of offers already assigned to the particular group (or account). After assignment of each offer, all the groups (or accounts) may be sorted based on their offer counters so that a group (or account) with fewer offers assigned may have a higher priority in receiving offers in subsequent assignment processes. Lift percentages, which are factors derived in advance from analysis of past offer targeting performance, may be applied to each group to adjust its number of accounts that remain available for offer assignments. The combined effect of offer counter based re-prioritization and application of lift percentages is to ensure that no customer population is “over-targeted” (i.e., assigned more offers than requested) at the expense of other populations being “under-targeted” (i.e., receiving too few offers). Another measure to the similar effect is to discontinue an offer as soon as it has been targeted at enough accounts in a statement month as requested by Marketing. The rule optimization algorithm may effectively enhance the business rules entered through the offer entry system to generate specific associations between the offers and the customer populations on group level and/or account level. This algorithm is described in detail in a co-pending U.S. patent application Ser. No. 10/869,904, entitled “System and Method for Offer Targeting”, naming as first-inventor “Adam M. Levine,” filed Jun. 18, 2004, which is hereby incorporated by reference herein in its entirety.
In step 108, the enhanced or optimized business rules may be built into one or more offer rule files for delivery to the subsequent offer management process. A number of options exist for the electronic packaging and delivery of business rules. For example, the rules may be compiled into an extensible markup language (XML) file or an ILOG™ Business Action Language (BAL) file. The building of a BAL rule file may involve the steps of identifying all the decision elements (e.g., factors that affect the targeting of offers at customer populations) based on inputs to the offer entry system and rule optimization, creating Java objects whose attributes are mapped to the decision elements, designing and populating staging tables to hold all the offers and rule data, and building BAL rules using ILOG™ application program interfaces (API's). Further, a link may be created in the offer entry system web interface for building the BAL rules. The BAL rules may be stored in an ILOG™ JRuleS™ repository.
In step 110, the offer rules may be applied to the outgoing statements to associate the offers with qualified accounts. First, all relevant data (including offer data and statement data) may be extracted, validated and staged for processing. Then the data may be compiled for subsequent rule processing. Next the offer rules may be executed against the accounts and output files may be created for statement composition, such that the statement data of each account is properly associated with its corresponding offers.
An exemplary process for applying the rules is illustrated in

In step 114, offer targeting output files may be created. The IQ tags that have been generated in step 110 and modified in step 112 may now be merged with their respective account data to create account-specific tag files. Then the tag files may be further merged with original statement files to generate output files. The original statement files typically include, among other things, offer placeholders at predetermined locations within the files. These placeholders may now be replaced with the IQ tags that represent qualified offers. The output files may now include all the information regarding association of offers with individual accounts and the placement of offers within each statement.
An exemplary embodiment of the tagging process and output file creation is illustrated in
Referring again to
In step 118, inventory management routines may be run to ensure proper supply of materials for production and insertion of the offers. An automated inventory system may be used to track and report inventory usage and availability.
In step 120, a results file may be generated. The results file may be a log that reflects, for each account, the number of qualified offers and the actual number of offers inserted in the statement both before and after weight management (step 112). The difference between these two numbers due to weight management is also accounted for in the results file. The results file may be reconciled with the offer rule file(s) and the offer targeting output files to provide feedback information of the offer management cycle. Such feedback information may be a basis for adjusting offer rankings and offer rules in future cycles.
In step 122, a suite of simulation tools may be run to facilitate integration and enhancement of the offer management functions as described above. These simulation tools may be run prior to a statement cycle, or concurrently with various offer management steps during a statement cycle, or at the end of a statement cycle. The simulations may be based on offer rules, offer targeting output files, inventory weights, weight management algorithm, results file, and inventory management.
For example, a manufacturing control simulation may be provided to better explain the link between offer targeting and inventory management. The simulation tool may receive the weight data of every insert, envelope, and paper stock from the inventory management system. The manufacturing control simulation may account for inventory weights, consider the average number of statement pages, replicate the weight management logic and set-up optimization routines, and predict “Qualification” and “Actuals” insertion figures for every offer ID.
According to one embodiment, a page weight simulation function may be provided, where the average number of pages per statement may be used to derive simulation results and account for the impact of statement sub-components (e.g., checks and coupons).
Other simulation functionalities may include, for example, the ability to run a single account through the simulator, and the ability to attach a file of accounts to run through the simulator. A system administrator or a super user may also create a virtual account, assign decision element values to the virtual account, and run it through simulation. Furthermore, a user may test run an entire cycle or an entire month of offers through simulation. Alternatively, the simulator may be run against previous months' historic data as well as current month's real-time account data. Further simulation may be provided to predict workflows and volumes amongst multiple statement production facilities. Once a super user reviews and approves the simulation results, they may be seamlessly exported to production facilities.

It should be appreciated that the system and method for offer management in accordance with the present invention is not limited to printed communications such as letters and statements. The offer management process may be useful in preparing electronic communications and web-based presentations as well. For example, a banking customer may receive electronic statements via E-mail or view the statements at an Internet website. For the E-mail channel, there may be file-size limitations analogous to postage weight limits encountered in the preparation of physical statements. For a web-based presentation, there may be limitations as to how many offer banners can fit within a viewer window. In these or other circumstances where there is limited communication capacity, it may be desirable to constrain the number of offers included for each account based on the offer management processes described above.
While the foregoing description includes many details and specificities, it is to be understood that these have been included for purposes of explanation only, and are not to be interpreted as limitations of the present invention. It will be apparent to those skilled in the art that other modifications to the embodiments described above can be made without departing from the spirit and scope of the invention. Accordingly, such modifications are considered within the scope of the invention as intended to be encompassed by the following claims and their legal equivalents.
