Requirement analysis and specification is the first major step in software development. The goal is to develop a requirements specification that contains all the customers' true needs. The analysis describes quality requirements and their constraints, such as cost and resources. Functional requirements are analyzed in terms of inputs, outputs and their relationships. Hence, requirements analysis enables software engineers to specify software function and establish software design and implementation constraints. The paper discusses the specification of individual fuzzy requirements using fuzzy sets.
