Requirements Engineering and Seven distinct tasks

Requirements Engineering and Seven distinct tasks

• The broad spectrum of tasks and techniques that lead to an understanding of requirements is called requirements engineering. 
• From a software process perspective, requirements engineering is a major software engineering action that begins during the communication activity and continues into the modeling activity. 
• It must be adapted to the needs of the process, the project, the product, and the people doing the work. 
• Requirements engineering builds a bridge to design and construction. 
• Requirements engineering provides the appropriate mechanism for understanding what the customer wants, analyzing need, ssessing feasibility, negotiating a reasonable solution, specifying the solution unambiguously, validating the specification, and managing the requirements as they are transformed into an operational system. 
• Seven distinct tasks 
• inception, 
• elicitation, 
• elaboration, 
• negotiation, 
• specification, 
• validation, and 
• management.
• Some tasks occurs in parallel.
