Embodiment Construction

[0036] In order to enable the public to fully understand the technical essence and implementation effects of the present invention, the applicant will describe in detail the specific implementation of the present invention below in conjunction with the accompanying drawings, but the applicant's description of the embodiments is not a limitation to the technical solution. Changes in the form of the inventive concept rather than in substance should be regarded as the protection scope of the present invention.

[0037] see figure 1 , the present invention relates to a demand change ripple effect analysis method, comprising the following steps:

[0038] S1) Extract requirement dependencies in the process of software problem analysis, and use requirement dependency graphs to model requirement dependencies;

[0039] S2) Use a requirement traceability matrix to describe the traceability relationship between user requirements, real world domains, and machine specifications in softwar...

Abstract

The invention discloses an analysis method for the spreading effect of a requirement change, and belongs to the technical field of software development. The analysis method comprises the steps that requirement dependencies are extracted in the software problem analysis process and modeled according to a requirement dependency diagram; the tracing relation among a real world field in a problem space, user requirements and software products in a machine specification-solution space is described through a tracing matrix; software requirement products affected by the requirement change are recognized through horizontal requirement change spreading effect analysis based on the requirement dependency diagram, and software design products and code products affected by the requirement change are recognized through vertical requirement change spreading effect analysis based on the tracing matrix; the software requirement products, the design products and the code products affected by the requirement change are collected to form a soft product set affected by the requirement change. The analysis method has the advantage that the problem that because the spreading effect of the requirement change is not effectively defined, the requirement change workload is difficult to estimate and requirement change management decisions are improper.

Description

technical field [0001] The invention belongs to the technical field of software development, and in particular relates to a demand change ripple effect analysis method, which is suitable for software demand change management. Background technique [0002] During the software life cycle, software requirements often change. There are many reasons for changes in software requirements, including omissions or errors in software requirements caused by insufficient requirements engineering, changes in business objectives, changes in the software use environment, new requirements raised by users or customers, etc. For most software projects, changes in requirements are inevitable and unpredictable. In order to protect the existing software and hardware investment market and gain a better competitive advantage, software companies must quickly respond to demand changes, define the ripple effects of demand changes, identify software products that need to be modified due to demand chan...
