Systems Requirement Analysis

In this chapter, systems requirements analysis is examined in greater detail. The syntax of the requirement and the nature of system requirements and their categorization are defined. In the Section 3.2, we review the techniques for capturing requirements, including the sources of requirements, the requests for proposals (RFP) structure, user interviews, surveys and questionnaires, observations, study of documents, standards, critical incident/accident reports, and the study of similar systems. Each technique is reviewed in detail, and their advantages and disadvantages are presented, for us to use the right technique for the right set of requirements. A large portion of the chapter is devoted to the methods and models for requirements analysis (RA). Major activities in RA are reviewed, and the three models that are commonly used in RA are presented. In the last section of the chapter, requirements management is briefly discussed. Examples of GENESYS are given at the end to show how a software tool can be utilized to implement management of the requirements.
