Software requirement priority setting method based on correlation relationship

Abstract

The invention discloses a software requirement priority setting method based on correlation relationship. The method comprises following steps: S1. establishing correlated sets and functional structure diagrams according to correlation among demands; establishing functional structure directed graphs by means of the influence relationship and determining whether there is a loop in the functional structure directed graphs; if there is a loop, removing the loop by performing model elaboration on the functional structure directed graphs to obtain functional structure directed graphs without loops;S2. using the ISM method and calculating according to the functional structure directed graphs without loops to establish a demand layer model and obtain multistage hierarchical directed graph; S3. generating a correlated demand set of each element in the highest layer of the multistage hierarchical directed graph; performing.

Description

technical field [0001] The invention relates to a method for setting priority levels of software requirements. More specifically, it relates to a software requirement priority setting method based on correlation. Background technique [0002] The software project development process is often limited by factors such as schedule, cost, and quality. It is inevitable that many requirements of the software product in the early stage will also be limited by the above factors. Therefore, it is very necessary to define the relative priority of the required product functions. Early in a software project, setting priorities can help project managers resolve conflicts, schedule deliverables, and make necessary trade-offs. Additionally, prioritizing requirements can help make it easier to re-scope a project when it faces delays. Prioritization of requirements is an intensive and difficult job, and dealing with prioritization is very helpful for maintaining project revenue and improvin...

Problems solved by technology

[0004] At present, whether it is the proportional scale or the sequential scale method in the demand prioritization method, the correlation between the demand objects is rarely mentioned when the demand is sorted. Although there is an HVC (Hierarchical Cumulative Voting) method, this method divides the demand into Several levels rely entirely on experience. Although the method has a layered idea and implicitly represents a certain correlation, it does not explicitly propose the correlation between objects, and lacks quantitative calculations.
