Requirement analysis method for information system integration service

Abstract

The invention relates to a requirement analysis method of an information system integration service, comprising following steps: (1) observing and discussing a service which needs to be integrated, so as to determine a target of integrated service process; (2) building a module of the integrated service process aiming at the target to be realized; (3) examining the module of the integrated service process, and correcting and adjusting repeatedly and circularly the module via finding out differences to be improved in the service process; (4) forming a system function report and a function data report; (5) processing a requirement confirmation for the module gained after being corrected; (6) processing system whole design and integration, running and detecting. The requirement analysis method of the information system integration service provided by the invention takes BPM as center, and processes service process structured analysis via building a service process structured module to realize service requirement analysis, so as to greatly simplify a course of integration information system requirement analysis and improve an efficiency and accuracy of the integration system requirement analysis.

Description

technical field [0001] The present invention relates to a method for analyzing business requirements of information system integration, in particular to a method with BPM (business process analysis) as the core, and describing the business process of information system integration by building a business process structure model, especially suitable for airport construction The various systems in the business integration. Background technique [0002] System integration is to integrate different software and hardware products, and on this basis, develop customized application software for customers, and finally complete the computer system that meets customer needs. In order to achieve the purpose of system integration, it is extremely important to conduct effective demand analysis for system integration. [0003] Such as figure 1 As shown, it is a schematic diagram of the method of demand analysis commonly used at present. This method uses a large number of discussion metho...

Problems solved by technology

During the analysis process, the understanding and discussion of the system requirements by all parties involved in the interview and communication is often limited to a certain part of the production or management of the enterprise, and there may also be deviations in the understanding of the same part by different groups of people. Aggregation is a method to clarify the overall requirements, and it lacks effective means to find deviations in requirements; the result is bound to be omissions, ambiguity, and contradictions

[0006] 2. The focus is not prominent: At present, many information system integration requirements analyzes more and more detailed analysis of single system function points, and less and rough analysis of nesting and processes between systems. Information system integration requirements analysis has become The combination of multiple information system requirements analysis, thus ignoring the key issue of "integration", did not achieve the global optimum

[0007] 3. Formation of integration shackles: In the current information system integration demand analysis process, the information system reality is often used as the blueprint, focusing on the current needs of users or the current functions of the system, and rarely considering some new requirements that may be required in the future. It is even more difficult to integrate future needs into the process of demand analysis in a timely and dynamic manner, causing the information system integration requirements to become outdated when they are confirmed, which virtually becomes the resistance for enterprises to continuously improve their business

[0013] In terms of forming integration shackles, the current airports integrate most of their energy into the current needs in the process of system integration, but today’s rapid internal and external environmental changes require the airport’s business model to also undergo rapid changes. However, now Some integrated systems not only cannot meet the future business needs, but also become the resistance to the improvement of the airport business model
