Evaluation of Software Requirement Complexity and Testing Method of Its Effectiveness
Sui Zhang · Zhongguo tiedao kexue · 2002
The software requirement description is a key factor that influences the design and preparation of software. The evaluation of the quality of the requirement description has depended heavily on the experience of the experts for a long time,being easy to missing items in the description and difficalt to find the problems and make improvement.Based on the objectoriented analysis method,this paper defines the qualitative measuring formulas of the accuracy, consistency, integrity, stability and complexity of the requirement description under the requirement description template,brings forward a method of testing the qualitative evaluation of the complexity and effectiveness during the software requirement phase. The analysis of the indicators of effectiveness and complexity shows that the method suggested in this paper can locate what is missing and the defects of the requirement description, evaluate the cost the requirement change and guide the software adaptability design.
