## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the acquisition of capital equipment and more particularly relates to a method and computer program for the acquisition of capital equipment using web-based purchase pooling.
2. Discussion of the Background
The Internet is considered the preferred marketplace for a variety of products including goods and services. Such products are commonly made available to users using client computers via one or more websites. Aggregate purchasing provides purchasers with leverage against sellers. The buying power of a group of people enables purchasers of the group to maneuver a seller to better terms than a single purchaser, thus providing considerable advantages to the purchasers of the group. For instance, the price point may be substantially lowered using aggregate purchasing.
Although web-based shopping has proliferated tremendously during the past few years, the collaborative acquisition of capital equipment has not been exploited. The purchase of capital equipment is complex and generally requires a detailed and complex request for proposal (“RFP”) from the purchaser to describe the technical specifications of the capital equipment. One or more sellers respond to the RFP with a proposed bid after possibly an extended negotiation. This type of complex purchase is different than existing consumer-based methods known in the art. This is especially true in the area of governmental procurement of capital equipment.
Thus, there does not exist an effective way in the prior art to handle the acquisition of capital equipment.
SUMMARY OF THE INVENTION
Accordingly, one aspect of the present invention is to provide a method for the acquisition of capital equipment using web-based purchase pooling that includes storing a default specification for capital equipment in a database, assigning a plurality of potential buyers to a purchasing pool, providing access to the default specification via a web-based system in communication with the database to the plurality of potential buyers using client devices over a network, receiving by the web-based system a plurality of customized specifications based on the default specification from one or more of the plurality of potential buyers via the client devices, determining by the web-based system common portions and non-common portions of the plurality of customized specifications based on a comparison of the plurality of customized specifications, selecting at least one of the non-common portions, and providing a request for proposal to at least one potential seller of capital equipment. The default specification is associated with the purchasing pool. The plurality of customized specifications are stored in the database. The request for proposal includes the common portions and the selected non-common portions.
Another aspect of the present invention is to provide a computer program product for the acquisition of capital equipment using web-based purchase pooling. The computer program product includes a first computer code for storing a default specification for capital equipment in a database, a second computer code for assigning a plurality of potential buyers to a purchasing pool, a third computer code for providing access to the default specification via a web-based system in communication with the database to the plurality of potential buyers using client devices over a network, a fourth computer code for receiving by the web-based system a plurality of customized specifications based on the default specification from one or more of the plurality of potential buyers via the client devices, a fifth computer code for determining by the web-based system common portions and non-common portions of the plurality of customized specifications based on a comparison of the plurality of customized specifications, a sixth computer code for selecting at least one of the non-common portions, and a seventh computer code for providing a request for proposal to at least one potential seller of capital equipment. The default specification is associated with the purchasing pool. The plurality of customized specifications are stored in the database. The request for proposal includes the common portions and the selected non-common portions.
Yet another aspect of the present invention is to provide a system for the acquisition of capital equipment using web-based purchase pooling. The system includes a database configured to store a default specification for capital equipment, a plurality of client devices for use by potential purchasers of capital equipment, and a web-based system in communication with the database and the plurality of client devices. The web-based system is configured to provide access to the default specification via a web-based system to the plurality of potential buyers using their respective client devices, to receive a plurality of customized specifications based on the default specification from one or more of the plurality of potential buyers via their respective client devices, to enable each of the potential purchasers to use their respective client devices to create a customized specification based on the default specification, to determine common portions and non-common portions of the plurality of customized specifications based on a comparison of the plurality of customized specifications, and to provide a request for proposal to at least one potential seller of capital equipment, wherein the request for proposal comprises the common portions and at least one of the non-common portions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, preferred embodiments of the present invention are described.
The present invention utilizes a web-based software package that enables purchasers of capital equipment to make such purchases under more favorable terms and reduced cost. In one embodiment, the purchasers are procurement professionals, public sector entities or similar governmental agencies. The buying power of any one agency is combined with the purchasing needs of other agencies having similar needs. The web-based software manages the process of pooling multiple enterprises, such as transit agencies, for the acquisition or procurement of capital equipment.
The present invention normalizes specification requirements across all purchasers, increasing process efficiencies for manufacturers by reducing the costs related to responding to numerous procurements through the bids process. Manufacturers spend millions of dollars preparing bids for individual solicitations. The present invention enables manufacturers to submit a single bid for many purchasers. Manufacturers may combine purchasing requirements into orders to generate planning and production efficiencies, thereby, further reducing costs.
The present invention also adds value to manufacturers through greater access and visibility to established and new customers. Manufacturers currently rely on bid notifications from their distribution channel or from publication of advertisements in local newspapers. There are so many discrete purchasers purchasing small quantities of capital equipment that manufacturers may miss many opportunities to participate or even to bid. A web-based implementation allows manufacturers to have access to all purchasers. Utilizing economies of scale and pooling resources results in great value to both purchasers and the manufacturers.
The present invention utilizes a web-based application that manages and facilitates the process of pooling multiple users for the acquisition of capital equipment, such as transit buses. Users are provided with the opportunity to join collaborative purchasing pools to increase the value and effectiveness each user participating in the pool. In one embodiment, users are provided with access to preliminary surveys in which the timing and type of purchases may be specified by individual users and collectively viewed such that the overall timing and type of purchases of all users may be evaluated. Preliminary surveys may be manual or automated. Optionally, data associated with the prior purchasing history of individual users or purchase pools may be used instead of preliminary surveys or used to supplement the preliminary surveys. Preliminary surveys may be followed by requirements analysis surveys in which detailed technical requirements may be obtained and serve as the basis of core capital equipment configurations. During this process, pool members may collaborate with manufactures to provide feedback on their specifications and requirements. Collaborative communication is possible between the pool members and the manufacturer, including without limitation through email, bulletin board, discussion forum, instant messaging, telephonic and online conferencing communication. Based on the collective requirements, a core specification is created. Any customization requirements may be separated from the core specification. For instance, the customized requirements of each user may be separated onto a deviation or variation list. The pool member requirements are aggregated and an acceptable standard request for proposal (“RFP”) package for the pool members overall is issued to manufacturers in accordance with the manufacturer's approval, notification, and other local terms, conditions and requirements. During the RFP process a pool member may optionally define weighting factors to be used for the evaluation criteria of whether to be included the RFP. The factors may be tied to individual specifications of the RFP package which if not satisfied will result in that pool member's non-participation in the RFP package or the automatic creation of variations or deviations based on the individual specifications.
The present invention facilitates and supports collaboration and discussions amongst pool members and manufacturers regarding:

    
    
        Requests for clarifications, changes, approved equals, and permitted exceptions to the RFP;
        Amendments to the RFP;
        Providing software assistance to users in reviewing technical proposals for conformance with the specifications;
        Facilitating communications with manufacturers to resolve questions, identify proposal deficiencies, and minimize any variations from the pooling concept;
        Supporting the preparation of a request for best and final offers (“BAFO”) for users to issue to manufacturers; and
        Providing software to be used by users in evaluating proposals, obtaining required approvals, and awarding contracts.
    
    


The present invention also provides technical assistance for explanations and recommendations regarding (i) the pooled procurement process, (ii) the core specification, pool specification, and deviations or variations, and (iii) responsibility determination, including methods criteria and process checklist, of prospective award of a purchaser's contract.
The present invention aggregates technical specifications, local/regional laws, local requirements, pricing/cost matrices, and commercial terms and conditions, as well as many other requirements associated with capital equipment procurement. In one embodiment, multiple pool members, such as transit authorities, use the portal as a template to input their vehicle requirements. A pool may be created by a user specifying and/or describing the type of capital equipment that the user desires to procure. For instance, a governmental transit agency may select a type of vehicle, such as a “40 ft Low-Floor CNG Bus/30 ft High-Floor Diesel Bus.” The web-based application provides a common interface for the gathering of each purchaser's unique and customized requirements. Once pool specifications are established, in one embodiment, the web-based application may be used to generate various matrices that allow for the comparison of each purchaser's requirements and specifications. The matrices may be generated by database queries and/or mathematical algorithms or the like. In another embodiment, the web-based application generates a collapsible XML structure that may be used for comparison of each purchaser's requirements and specifications. This comparison allows for the pool members to see their common needs versus other purchasers as well as the common needs of the purchasing pool as a whole. The application guides pool members through not only the creation of their online specification, but provides the framework for interactive collaboration as the purchasers evaluate the various matrices.
The web-based application delivers a common specification with options derived from multiple authorities entering individual specifications using the web-based interface. The preferences of each participating purchaser are recognized such that their unique requirements may be individually realized. A bid evaluation pricing matrix is provided to calculate multiple bus specifications and equipment configurations for price comparisons and the final cost.
In one embodiment, the functionality is divided into separate areas based on the “roles” the users have been assigned. Those roles include without limitation “admin users,” “agency users” and “vendor users.” Obviously, other users and/or roles and user names are possible within the scope of the present invention.
An admin user performs administrative tasks such as creating users, activating and closing pools and editing users. The admin user may also create a pool default specification to be used as a starting point for specifications during the procurement process. The admin user may optionally specify a list of users they would like to invite to the purchasing pool. The list of users to be invited to the purchasing pool may also be automatically selected based on historical information such as previous purchases and purchasing pool participation.
An agency user is a member of a pool. Agency users participate by entering their preferences using online specification forms, text revision entries, and custom entries. In one embodiment, one of the agency users is designated as the lead agency user and may have similar responsibilities as the admin users such as creation of a new pool, creating a default specification and designating users as members of the pool.
A vendor user is a limited access user and is generally not allowed access to the specification building process. The vendor user can join a purchasing pool to specify information used in bid evaluation and to create any approved equals. Optionally, an agency user may “what if” pricing based on the addition and/or removal of elective deviations the manufacturer has made available. The vendor approved equals are alternatives to the specification supplied by the pool members in the request for purchase.
Referring to FIGS. 1-3, flow charts illustrating the acquisition of capital equipment using web-based purchase pooling are shown. At block 10, one or more pools are assembled. Pool assembly includes without limitation creating a new pool and associating one or more users as pool members. This step may include specifying the type associated with the pool member, such as lead agency user, agency user or the like. Pool members may include existing users or newly added users. In one embodiment, new users are solicited to join a newly created pool by email, instant messaging, message board communication, teleconferencing, or by traditional marketing means. A base or default specification may also be created and stored in database 83, as shown in FIG. 4. The base specification may be automatically or manually created.
Pool members may communicate with web-based system 82 over network 88, such as the Internet, using client devices 84a-84n. Client devices 84a-84n may include without limitation desktop computers, laptop computers, servers, palmtop or other hand-held computers, personal digital assistants, Internet enabled mobile phones, Internet appliances and the like.
At block 20, one or more pool members collaborate on an RFP package. Collaboration on an RFP package includes without limitation development of a specification by individual pool members, at block 22. Collaboration may be accomplished between the pool members by any means including without limitation personal contact, email, bulletin board, discussion forum, instant messaging, telephonic and online conferencing communication. For instance, pool members using client devices 84-84n in communication with web-based system 82 over network 88, such as the Internet, may collaborate on an RFP using discussion boards hosted on web-based system 82.
Each pool member may specify deviations and/or variations to the base specification. One or more pool members collaborate for the acquisition of capital equipment and the creation of a joint specification, at block 24. A joint specification includes core features of the capital equipment. In one embodiment, the user preferences, also known as deviations or variations, are assigned a priority and incorporated into the core features based on the priority. The pool member with the largest number of units is given the highest priority with respect to user preferences incorporated as core features. In another embodiment, multiple pool members having the same user preferences for one or more portions of the specification may be grouped together. In effect, group the individual pool members forms a voting group or proxy. If the pool members of this group collectively have the largest number of units then their user preferences are given the highest priority. In yet another embodiment, the priority is base on weighting factors specified by individual pool members for different portions of the specification, at block 26. At block 28, terms and conditions for individual pool members are added to the core specification. In one embodiment, the individual terms and conditions are added as addendums to the core specifications. The core specification provides the advantages of pooled members including volume discounting whereas the terms and conditions provide the pool members with the ability to customize their preferences while still remaining a member of the purchasing pool. After the pool members have collaborated in developing an RFP package, the RFP is published, at block 30.
Vendors may communicate with web-based system 82 over network 88, such as the Internet, using vendor devices 86a-86n. Vendor devices 86a-86n may include without limitation desktop computers, laptop computers, servers, palmtop or other hand-held computers, personal digital assistants, Internet enabled mobile phones, Internet appliances and the like.
The vendor prepares a bid proposal at block 40. As shown at blocks 42-46, the bid proposal preparation includes without limitation creating and editing a discount schedule, creating and editing approved equals, and establishing pricing. The preparation of a bid proposal may also include collaboration with the pool members. At block 50, the vendor bid is submitted to the pool members for their evaluation. At block 60, the bid proposal is evaluated by the pool members. If the pool members agree to the bid proposal, then a contract based on the bid proposal is awarded at block 70. If the pool members do not agree on the bid proposal, then one or more of the above steps may be repeated.
Referring to FIGS. 5-21, an exemplary web-based purchase pooling computer program according to the present invention is shown. According to this example, a pool member may select a pool to participate from a list of purchasing pools, as shown at 100. The list of purchasing pools displayed may be limited to those purchasing pools that the user has been invited to participate as a pool member. As shown at 110, a purchasing pool may include a pool description generally describing the capital equipment to be purchased by members of the purchasing pool. New pool members may be solicited to join a newly created purchasing pool, as shown at 120. During the web-based purchase pooling process, pool members may collaborate by any means including message discussion boards, as shown at 130. Because of the complexity of an RFP that is often required to purchase capital equipment, the technical specification to be used for the RFP may be separated into different sections, as shown in 140 and 200. A pool member may either utilize the fields in the default specification or enter customized user preferences, as shown in 150 and 210. For instance, a portion of a default specification is shown at 160. After completing one or more sections of the technical specification, a user may elect to view a proposed RFP based on the then-completed sections, as shown at 170 and 180. The pool member may also add customized addendums and/or text revisions to a proposed RFP, as shown at 190 and 220. An aggregation matrix may be provided to view customized portions of the proposed RFP, as shown at 230 and 240. The pool member may also compare differences in prices and specifications, as shown at 250 and 260. It is to be understood that the present invention is not limited to the web-based purchase pooling computer program shown in FIGS. 5-21 and that these figures are instead provided as one possible example.
The present invention thus includes a computer program which may be hosted on a storage medium and includes instructions which perform the processes set forth in the present specification. The storage medium can include, but is not limited to, any type of disk including floppy disks, optical disks, CD-ROMs, magneto-optical disks, ROMs, RAMs, EPROMs, EEPROMs, flash memory, magnetic or optical cards, or any type of media suitable for storing electronic instructions.
Obviously, many other modifications and variations of the present invention are possible in light of the above teachings. The specific embodiments discussed herein are merely illustrative, and are not meant to limit the scope of the present invention in any manner. It is therefore to be understood that within the scope of the disclosed concept, the invention may be practiced otherwise then as specifically described.
