Reliability Management in Software Requirement Analysis

Reliable software should be correct, intact, unanimous and robust. However, software reliability could only be measured by software testing. If there are reliability faults in the completed software system, it would be too late to change the software design. What causes such situation is that we deal uneffectively with the software reliability management (SRM) in software life cycle (SLC). For avoiding this kind of situation, we proposed that the strict testing and manage of software reliability should be carried out at initial stage of software engineering - software requirements analysis (SRA). In this paper, we introduced two methods to implement SRM according with the different SRA models; one is based on structured analysis and the other is based on object-oriented analysis (OOA). By using evolutionary prototype, the software reliability quotas (SRQ) can be tested at the stage of requirements analysis. At last, we give some advice about how to select evaluation model of software reliability
