Embodiments of the invention relate generally to data modeling activities, and more particularly, to a method, system, and storage medium for implementing a multi-stage, multi-classification sales opportunity modeling system.
In any sales business, an enterprise typically evaluates opportunity data in order to forecast demands for its offerings. The forecasts may be used to predict the enterprise's future financial performance and the enterprise may develop business plans to achieve their financial goals. Usually, the evaluation of sales opportunities is performed manually by human experts without significant assistance from decision-aid tools. Human error, shortage of skills, and evaluation costs are major concerns with existing evaluation processes. Moreover, a financial and business plan that is based upon inaccurate or inadequate forecasts may cause irreparable harm to the business.
What is needed, therefore, is a sales opportunity evaluation process that provides an enterprise with confidence that there will be a substantial likelihood of success should the opportunity be exploited.
Exemplary embodiments relate to a method, system, and storage medium for implementing a multi-stage, multi-classification sales opportunity modeling system. The method includes receiving operational data relating to past sales activities and receiving parameters identified as being relevant in determining a likelihood of whether exploitation of a sales opportunity will be successful. The method also includes generating a multi-stage model by applying the operational data and the parameters to an analytic engine for evaluating different factors affecting success of the sales opportunity.
The system for implementing the multi-stage, multi-classification sales opportunity modeling system includes a processor executing a sales opportunity modeling application and a storage device housing operational data relating to past sales activities. The sales opportunity modeling application receives parameters identified as being relevant in determining a likelihood of whether exploitation of a sales opportunity will be successful. The sales opportunity modeling application also generates a multi-stage model by applying the operational data and the parameters to an analytic engine for evaluating the different factors affecting success of the sales opportunity.
The storage medium is encoded with machine-readable program code for implementing a multi-stage, multi-classification sales opportunity modeling system. The program code includes instructions for causing a processor to implement a method. The method includes receiving operational data relating to past sales activities and receiving parameters identified as being relevant in determining a likelihood of whether exploitation of a sales opportunity will be successful.

Turning now to
The host system 102 may also operate as an application server. The host system 102 executes one or more computer programs to implement sales opportunity modeling system activities. These one or more computer programs are referred to collectively herein as a sales opportunity modeling system application 108. In exemplary embodiments, sales opportunity modeling system application 108 includes a data mining component, feature subset selection component, and analytic engine. Alternatively, the data mining component, feature subset selection component, and analytic engine may be implemented independently of the sales opportunity modeling system application 108. Processing of sales opportunity modeling system activities may be shared by the client system 104 and the host system 102 by providing an application (e.g., java applet) to the client system 104. Alternatively, client system 104 may include stand-alone software applications for performing a portion or all of the processing described herein. As previously described, it is understood that separate servers may be utilized to implement the network server functions and the application server functions. Alternatively, the network server and the application server may be implemented by a single server executing computer programs to perform the requisite functions.
Client system 104 may be coupled to host system 102 via network 106. Further, client system 104 may be implemented using a general-purpose computer executing a computer program for carrying out some of the processes described herein. The client system 104 may be a personal computer (e.g., a lap top, a personal digital assistant) or host attached terminals. If client system 104 is a personal computer, the processing described herein may be shared by client system 104 and host system 102 (e.g., by providing an applet to client system 104). For purposes of illustration, client system 104 is operated by a product development engineer or specialist.
Network 106 may be any type of known network including, but not limited to, a wide area network (WAN), a local area network (LAN), a global network (e.g. Internet), a virtual private network (VPN), and an intranet. The network 106 may be implemented using a wireless network or any kind of physical network implementation known in the art. Client system 104 may be coupled to the host system 102 through multiple networks (e.g., intranet and Internet) so that not all client systems are coupled to the host system 102 through the same network. One or more of the client systems and the host system 102 may be connected to the network 106 in a wireless fashion. In one embodiment, the network is an intranet and one or more client systems execute a user interface application (e.g. a web browser) to contact the host system 102 through the network 106 while another client system may be directly connected to the host system 102.
In exemplary embodiments, the sales opportunity modeling system shown in
In accordance with exemplary embodiments, databases in storage device 110 include an historical database 112 and sales opportunity database 114. Historical database 112 may house operational data of a business enterprise executing the sales opportunity modeling system application 108. Operational data may include sales information such as orders for goods and/or services placed by customers, orders satisfied by the enterprise, canceled orders, orders placed but not satisfied by the enterprise, etc. This information is typically in the form of invoices, receipts, shipping documents, and similar types of records. Supplemental information may also be stored in historical database 112 that relates to the above-described sales data. For example, logistical issues that prevented sales orders from being satisfied (e.g., inadequate resources, supplier deficiencies, defects in manufacturing processes, and economic or regulatory issues. Likewise, information that provides reasons for which customers have canceled orders may be stored in historical database 112 (e.g., product recall announcements, a competitor's product that is new to the market, inadequate marketing efforts, etc.). It will be appreciated that a variety of additional information may also be stored in historical database 112 as desired by the enterprise.
Sales opportunity database 114 may store information obtained by the enterprise regarding customer demand or needs. Marketing, research and development (R&D), and/or sales groups typically scope out customer needs and wants through responses to surveys and various methods of research in order to identify opportunities for developing new and enhanced products and services. This type of information is stored in sales opportunity database 114.
Also stored in storage device 110 are detection stage model database 116, verification stage model database 118, and justification stage model database 120. Each multi-stage model includes three stage models and is formulated via the execution of sales opportunity modeling system application 108 using data obtained from historical database 112, which in turn, produces a detection stage model, verification stage model, and justification stage model. Sales opportunity data in database 114 is then applied to the model in order to evaluate potential sales opportunities as described further herein.
Turning now to
The sales opportunity modeling system application 108 prompts the user to enter desired parameters or candidate features that are considered relevant in predicting the success and failure for a sales opportunity. For example, a time period may be relevant in determining the success of an opportunity (e.g., Christmas season for children's toys). The sales opportunity modeling system application 108 performs data extraction and cleansing on the data in historical database 112 at step 206. This step includes filtering the documents (e.g., receipts, invoices, etc.) and collecting the relevant data from these documents (e.g., product name, number of orders, pricing and payment information, etc.). It will be understood that step 206 may be performed well in advance of generating the stage model(s) described in
The filtered data is then loaded into local storage device 111 in accordance with the specific modeling stage being addressed at step 208. The first stage to be modeled is the detection stage. Accordingly, in exemplary embodiments, only the filtered data relevant to the detection stage is loaded into local storage device 111.
Utilizing the parameters selected by the user in step 204, the loaded data is processed using, e.g., a feature subset selection process at step 210. The feature subset selection process identifies which of the loaded data are applicable to the parameters selected by the user. The processes executed by the feature subset selection process are well known in the data mining community and will be understood by those skilled in the art.
The sales opportunity modeling system application 108 creates training and testing datasets using filtered data from historical database 112 at step 212. The training and testing datasets may be automatically provided by the sales opportunity management system application 108 or a user may enter specific data via the TRAIN option 308 and/or TEST option 310, respectively, of user interface screen 300 of
If the testing produces favorable results at step 218, it is determined whether all three stages have been modeled at step 220. As described above, since the detection phase only has been modeled, the process returns to step 208 whereby the sales opportunity modeling system application 108 loads the filtered data that applies to the verification stage into local storage device 111 and the process described in steps 210-220 are repeated until each stage (i.e., detection, verification, and justification) has been modeled. Once all stages have been successfully modeled at step 220, the sales opportunity modeling system application 108 generates a final multi-stage model, a sample of which is shown and described in
Turning now to
It is assumed for purposes of illustration, that a user has accessed the sales opportunity modeling system application 108 and selected APPLY MODEL option 306 from user interface screen 300 of
The sales opportunity modeling system application 108 then inputs the remaining sales opportunity information to the detection stage model 406. The detection stage model 406 has been trained (via the process described in
If the result of the detection stage model indicates that a sales opportunity is likely to be successful (as reflected in
As with the detection stage model 406, the verification stage model 414 also provides multi-classification output of its results (shown as Sv 418 for successful results, and Fv 416 for failure results and reasons therefore). The reasons may be gleaned from the processing of documents stored in historical database 112 Upon completion of the verification stage model processing, the results may indicate that the sales opportunity is undesirable along with the reason(s) therefore. The user may evaluate the reasons for the failure and either abort the sales opportunity (i.e., the processing does not continue to the next stage model) or may modify the sales opportunity information and return it to the verification phase for reprocessing.
If the result of the verification stage model 414 indicates that a sales opportunity is likely to be successful (as reflected in
As with the detection and verification stage models 406 and 414, the verification stage model 422 also provides multi-classification output of its results (shown as Sj 426 for successful results, and Fj 424 for failure results and reasons therefore). The reasons may be gleaned from the processing of documents stored in historical database 112. Upon completion of the justification stage model processing, the results may indicate that the sales opportunity is undesirable along with the reason(s) therefore. The user may evaluate the reasons for the failure and either abort the sales opportunity (i.e., the processing does not continue to the next stage model) or may modify the sales opportunity information and return it to the justification for reprocessing. If the results indicate that the sales opportunity is desirable, the enterprise moves forward with plans to exploit the opportunity.
The sales opportunity modeling system of the present invention may reside on a stand-alone computer system which may have access to the Internet, or may reside on a computer system which is part of the network through which there is Internet access. With a connection to a network and/or the Internet, there are several different ways in which the process software used to implement the systems and methods of the present invention may be integrated with the network, and deployed using a local network, a remote network, an e-mail system, and/or a virtual private network. The following descriptions review the various ways of accomplishing these activities.
Integration of Sales Opportunity Modeling System Software. To implement the sales opportunity modeling systems and methods of the present invention, process software, which is composed of the software as described above and related components including any needed data structures, is written and then if desired, integrated into a client, server, and network environment. This integration is accomplished by taking those steps needed to enable the process software to coexist with other application, operating system and network operating system software and then installing the process software on the clients and servers in the environment where the process software will function. An overview of this integration activity will now be provided, followed by a more detailed description of the same with reference to the flowcharts of
The first step in the integration activity is to identify any software on the clients and servers where the process software will be deployed that are required by the process software or that need to work in conjunction with the process software. This includes the network operating system, which is the software that enhances a basic operating system by adding networking features.
Next, the software applications and version numbers are identified and compared to the list of software applications and version numbers that have been tested to work with the process software. Those software applications that are missing or that do not match the correct version are upgraded with the correct version numbers. Program instructions that pass parameters from the process software to the software applications will be checked to ensure the parameter lists match the parameter lists required by the process software. Conversely, parameters passed by the software applications to the process software will be checked to ensure the parameters match the parameters required by the process software. The client and server operating systems including the network operating systems are identified and compared to the list of operating systems, version numbers, and network software that have been tested to work with the process software. Those operating systems, version numbers, and network software that do not match the list of tested operating systems and version numbers are then upgraded on the clients and servers to the required level.
After ensuring that the software resident on the computer systems where the process software is to be deployed is at the correct version level(s), that is, has been tested to work with the process software, the integration is completed. This is done by installing the process software on the clients and servers. Armed with the foregoing overview of the integration activity, the following detailed description of the same should be readily understood.
Referring to
Step 514, which follows either step 502, 508 or 512, determines if there are any programs of the process software that will execute on the clients. If no process software programs execute on the clients, the integration proceeds to step 520 and exits. If there are process software programs that will execute on clients, the client addresses are identified at step 516.
At step 518, the clients are checked to see if they contain software that includes the operating system (OS), applications, and network operating systems (NOS) software, together with their version numbers, that have been tested with the process software. The clients are also checked at step 518 to determine if there is any missing software that is required by the process software.
At step 522, a determination is made if the version numbers match the version numbers of OS, applications and NOS that have been tested with the process software. If all of the versions match, and there is no missing required software, then the integration proceeds to step 520 and exits.
If one or more of the version numbers do not match, then the unmatched versions are updated on the clients with the correct versions at step 524. In addition, if there is missing required software, then it is updated on the clients as part of step 524. The client integration is completed by installing the process software on the clients at step 526. The integration proceeds to step 520 and exits.
Deployment of Sales Opportunity Modeling System Software. It should be well understood that the process software for implementing the sales opportunity modeling system of the present invention may be deployed by manually loading the process software directly into the client, server, and proxy computers from a suitable storage medium such as a CD, DVD, etc.. It is useful to provide an overview of still other ways in which the process software may also be automatically or semi-automatically deployed into one or more computer systems. The process software may be deployed by sending or loading the process software to a central server or a group of central servers. From there, the process software may then be downloaded into the client computers that will execute the process software. Alternatively, the process software may be sent directly to the client system via e-mail. The process software is then either detached to a directory or loaded into a directory by a button on the e-mail that executes a program that detaches the process software attached to the e-mail into a directory. Another alternative is to send the process software directly to a directory on the hard drive of a client computer. Also, when there are proxy servers, the automatic or self-automatic deployment process will select the proxy server code, determine on which computers to place the proxy servers' code, transmit the proxy server code, and then install the proxy server code on the proxy computer. The process software will be transmitted to the proxy server and then stored on the proxy server. Armed with this overview of the possible deployment processes, the following detailed description of the same with reference to
Step 600 begins the deployment of the process software. It is determined whether there are any programs that will reside on a server or servers when the process software is executed at step 602. If the answer is “yes”, then the servers that will contain the executables are identified, as indicated in step 636 in
Next, as shown in step 604 in
Next, as shown at step 618, a determination is made if a proxy server is to be built to store the process software. A proxy server is a server that sits between a client application, such as a Web browser, and a real server. It intercepts all requests to the real server to see if it can fulfill the requests itself. If not, it forwards the request to the real server. The two primary benefits of a proxy server are to improve performance and to filter requests. If a proxy server is required, then the proxy server is installed as indicated at step 620. Next, the process software for implementing the present invention is sent to the servers, as indicated in step 622 either via a protocol such as FTP or it is copied directly from the source files to the server files via file sharing. Another way of sending the process software to the servers is to send a transaction to the servers that contained the process software and have the server process the transaction. In this manner, the process software may be received by and copied into the server's file system. Once the process software is stored at the servers, the users via their client computers, then access the process software on the servers and copy it into to the file systems of their client computers at step 624. Another alternative is to have the servers automatically copy the process software to each client and then run the installation program for the process software at each client computer. Either way, the user computer executes or causes to be executed the program that installs the process software on the client computer at step 642, then the process exits at step 616.
Continuing now at step 608 in
Continuing at step 612 (see bottom of
Use of Virtual Private Networks for Sales Opportunity Modeling System Software. The process software may be deployed, accessed and executed through the use of a virtual private network (VPN). A VPN is any combination of technologies that can be used to secure a connection through an otherwise unsecured or untrusted network. VPNs are used to improve security and can often also reduce operational costs. The VPN makes use of a public network, usually the Internet, to connect remote sites or users together. Instead of using a dedicated, real-world connection such as a leased line, the VPN uses “virtual” connections routed through the Internet from the company's private network to the remote site or employee(s). Access to the software via a VPN can be provided as a service by specifically constructing the VPN for purposes of delivery or execution of the process software (i.e., the software resides elsewhere). In such an instance, the lifetime of the VPN is often limited to a given period of time or to a given number of deployments based on an amount paid.
The process software may be deployed, accessed, and executed through either a remote-access VPN or a site-to-site VPN. When using a remote-access VPN, the process software is typically deployed, accessed, and executed via the secure, encrypted connections between a company's private network and remote users through a third-party service provider. The enterprise service provider (ESP) sets up and/or authorizes access to a network access server (NAS) and provides the remote users with desktop client software for their computers. The telecommuters can then dial a phone number (often a toll-free number) or attach directly via a cable, DSL, or wireless modem to reach the NAS and use their VPN client software to access the corporate network and to access, download, and execute the process software.
When using a site-to-site VPN, the process software is typically deployed, accessed and executed through the use of dedicated equipment and large-scale encryption. These tools are often used to connect multiple fixed sites of a larger company over a public network such as the Internet.
The process software is transported over the VPN via a process called tunneling. Tunneling is process involving the placing of an entire packet within another packet and sending it over a network. The protocol of the outer packet is understood by the network and by both points, called tunnel interfaces, where the packet enters and exits the network. Tunneling generally encapsulates the private network data and protocol information within the public network transmissions so that the private network protocol information appears to the public network simply as unintelligible data. Armed with the foregoing overview of virtual private networks and how they operate and how they may be used to transport the process software, the following more detailed description of same with reference to the flowcharts of
Step 700 in
If a remote access VPN does exist, then flow proceeds to step 710 in
Returning to step 710 in
Returning now to step 704 in
After the site-to-site VPN has been built or if it had been previously established, the users access the process software via the VPN as indicated in step 726. Next, the process software is transported to the site users over the network via tunneling as indicated in step 728. As previously explained, the process software is divided into packets and each packet including the data and protocol is placed within another packet, as indicated in step 730. When the process software arrives at the remote user's desktop, it is removed from the packets, reconstituted, and is executed on the site users desktop at step 732. The process then proceeds to step 706 and exits.
On Demand Computing for Sales Opportunity Modeling System Software. The process software for implementing the sales opportunity modeling system of the present invention may be shared; that is, it may be used to simultaneously serve multiple customers in a flexible, automated fashion. It is process software that is easily standardized, requiring little customization, and it is scalable, thus providing capacity on demand in a pay-as-you-go model known as “on demand” computing. An overview of on demand computing as applied to the sales opportunity modeling system software will now be provided, followed by a more detailed description of same made with reference to the flowcharts of
The process software for implementing the present invention can be stored on a shared file system accessible from one or more servers. The process software may be executed via transactions that contain data and server processing requests that use measurable CPU units on the accessed server. CPU units are units of time such as minutes, seconds, and hours on the central processor of the server. Additionally, the accessed server may make requests of other servers that require CPU units. CPU units are an example that represents but one measurement of use. Other measurements of use include, but are not limited to, network bandwidth, memory usage, storage usage, packet transfers, complete transactions, etc.
When multiple customers use the same process software application, their transactions are differentiated by the parameters included in the transactions that identify the unique customer and the type of service for that customer. All of the CPU units and other measurements of use that are used for the services for each customer are recorded. When the number of transactions to any one server reaches a number that begins to affect the performance of that server, other servers are accessed to increase the capacity and to share the workload. Likewise, when other measurements of use such as network bandwidth, memory usage, storage usage, etc., approach a capacity so as to affect performance, additional network bandwidth, memory usage, storage etc. are added as needed to share the workload.
The measurements of use used for each service and customer are sent to a collecting server that sums the measurements of use for each customer for each service that was processed anywhere in the network of servers that provide the shared execution of the process software. The summed measurements of use units are periodically multiplied by unit costs and the resulting total process software application service costs are alternatively sent to the customer and or indicated on a web site accessed by the customer who then remits payment to the service provider.
In another embodiment, the service provider requests payment directly from a customer account at a banking or financial institution. In yet another embodiment, if the service provider is also a customer of the customer that uses the process software application, the payment owed to the service provider is reconciled to the payment owed by the service provider to minimize the transfer of payments. Armed with the foregoing overview, the detailed description of the on demand computing with respect to the process software, and the following detailed description of same with reference to
Step 800 begins the On Demand process. A transaction is created that contains the unique customer identification, the requested service type and any service parameters that further specify the type of service as indicated in step 802. The transaction is then sent to the main server as shown in step 804. In an On Demand environment, the main server may initially be the only server. Then, as capacity is consumed, other servers are added to the On Demand environment.
The server central processing unit (CPU) capacities in the On Demand environment are queried at step 806. The CPU requirement of the transaction is estimated, then the servers' available CPU capacity in the On Demand environment are compared to the transaction CPU requirement to see if there is sufficient CPU available capacity in any server to process the transaction as indicated in step 808. If there is not sufficient server CPU available capacity, then additional server CPU capacity is allocated to process the transaction as indicated in step 816. If there was already sufficient available CPU capacity, the transaction is sent to a selected server at step 810.
Before executing the transaction, a check is made of the remaining On Demand environment to determine if the environment has sufficient available capacity for processing the transaction as indicated at step 812. This environment capacity consists of elements such as, but not limited to, network bandwidth, processor memory, storage, etc. If there is insufficient available capacity, then capacity will be added to the On Demand environment as indicated in step 814. Next the required software to process the transaction is accessed, loaded into memory, and the transaction is executed as indicated in step 818.
The usage measurements are recorded as indicated in step 820. The usage measurements consist of the portions of those functions in the On Demand environment that are used to process the transaction. The usage of functions such as, but not limited to, network bandwidth, processor memory, storage and CPU cycles are what is recorded. The usage measurements are summed, multiplied by unit costs, and then recorded as a charge to the requesting customer as indicated in step 822.
If the customer has requested that the On Demand costs be posted to a web site as indicated in step 824, then they are posted to a web site at step 826. If the customer has requested that the On Demand costs be sent via e-mail to a customer address as indicated in step 828, then they are sent to the customer via e-mail as indicated in step 830. If the customer has requested that the On Demand costs be paid directly from a customer account at step 832, then payment is received directly from the customer account at step 834. The On Demand process proceeds to step 836 and then exits.
