A second step of establishing a selection guideline which provides a guideline and a method for detailed activities and step-by-step linkage schemes so as to be able to do so; And a third step of supporting these processes directly on the web with reference to the outputs of the first and second steps, a computer-readable recording medium having recorded thereon a program capable of executing the steps.

In the following, with reference to the accompanying drawings, a preferred embodiment according to the present invention will be described in detail.

1 is a diagram illustrating an environment of a web-based ERP introduction and selection support system to which the present invention is applied.

The ERP introduction and selection support system shown as an example to which the present invention is applied includes the introduction and selection support model 110 corresponding to the logical methodology for the introduction and selection process, and the procedures and methods defined in the introduction and selection support model 110. If the user wants to introduce the ERP in the actual enterprise environment, while performing the necessary input and output interface, and stores the detailed analysis information about the introduction and selection system 120, ERP products and suppliers to perform step-by-step decision making, Between the introduction and selection support DB 130 that provides the necessary information in the product evaluation step of the introduction and selection system 120 and components such as the introduction and selection support model, the introduction and selection system, and the introduction and selection support DB. Web BBS 140 provides an integrated environment by implementing an interface and an additional information providing environment.

2 is an explanatory diagram showing functions processed in an ERP introduction and selection support system according to an embodiment of the present invention.

As an example to which the present invention is applied, the introduction background and the present situation analysis which define the goal to introduce the ERP system by deriving the company status analysis data based on the work environment related information inside the company with the management goal of the company as a constraint ( A1), based on the company status analysis data derived from the background and status analysis (A1) and information on the business process of the company, the BPR (Business Process Reengineering) implementation strategy is introduced in relation to the introduction of the ERP system. Establish an implementation strategy (A2) to determine the extent to which ERP will be introduced in relation to the establishment of information system vision and the scope of work and organizational structure of the enterprise (A2); Based on A1) and establishment of introduction strategy (A2), a general evaluation of the target ERP product is performed to receive the input of the DB of the proposed item. Proposal evaluation and product selection (A4) function that generates RFP (Request For Proposal), RFP preparation and proposal evaluation preparation (A3) and DB information to calculate the product evaluation result of the proposal from the vendor. Consists of.

3 is a flowchart illustrating a method of constructing an ERP introduction and selection support system according to an embodiment of the present invention.

First of all, preliminary surveys and basic foundation surveys of companies are carried out, and an information strategy plan is established with reference to the results, and organizational analysis, data status analysis, process status analysis, and information-based status analysis are performed.

Subsequently, the system vision is set based on the analysis results of the present conditions, and then items for selecting an ERP product are derived. At this time, the resource information and product information database already established according to the technology trend and product characteristics are used.

After that, the software and system requirements are summarized using the resource information database and each requirement cleanup result to support RFP creation, and after selecting an ERP product using the product information database, an ERP is constructed.

4 is a configuration diagram of an ERP introduction and selection support system according to an embodiment of the present invention. The ERP introduction and selection support system according to an embodiment of the present invention includes a server computer 410 and a plurality of client computers 420. , A data server computer 430 and a development programming language 440.

The server computer 410 can be operated on a personal computer of a plurality of clients 420 as compared to Unix, easy to install a development system, and CGI (Computer Graphics Interface) for database interworking in a web environment. And an operating system capable of supporting an attached support processor (ASP). A communication using a web browser is performed between the ERP introduction selection support system mounted on the server computer 410 and the work software mounted on the client computer 420 for processing according to the work flow. Since the data server computer 430 is for data storage by interworking with CGI and ASP, data may be stored in one database on one computer.

5A, 5B, and 5C are diagrams illustrating an ER diagram and a database schema expressing correlations between data in an ERP introduction and selection support system according to an embodiment of the present invention. .

Referring to FIG. 5A, the ERP introduction selection system is composed of a user database, a product and vendor database, an introduction selection database, a related site database, and an introduction case database, and defines entities according to a subject area constituting these databases. You can see the relationship between each subject. The introduction and selection system subject is a parent subject that includes a 'product introduction' subject and a 'system user' subject, and has 'product' and 'expert user' as core entities, and the introduction and selection system subject is a 'user' It has a case of 'star selection selection' as a core entity.

In addition, the introduction case subject has 'introduced product' and the related site subject has 'site' as its core entity. In addition, bulletin board subjects have a bulletin board as a core entity and are stored in a database separate from other subjects.

FIG. 5B shows the relationship between the entities of each subject of the introduction and selection system in an ER diagram. The most important entity is the user selection case, which is a total of 51 tables A1-D31. The total number of fields consists of 2,716 fields.

FIG. 5C is an exemplary diagram illustrating a table of the entities shown in FIGS. 5A and 5B and includes a field name, a data type, a length, and a remarks area.
