Chapter 6: HOMEWORK ASSIGNMENT due November 20, 2014
1. List and describe at a high level the steps involved in software requirements engineering process.
Elicitation: is the practice of collecting the requirements of a system from users, customers and other stakeholders.
Analysis: after the requirements are elicited and collected the set of data still unorganized that means that they must still be analyzed. The analysis consists in two main tasks: Categorizing or clustering the requirements and Prioritizing the requirements.
Documentation and Definition: is an activity that comes after requirements analysis. In fact, it overlaps with requirements analysis and should be looked upon as a set of iterative activities within the broader context of analysis. Requirements definition involves formally spelling out the requirements.
Prototyping: is the activity of creating prototypes of software applications. A prototype typically simulates only a few aspects of the final product and may be completely different from it.
Review and validation: whichever review technique you choose, it is important to realize that reviewing requirements with users and customers is an essential part of the requirements analysis and prototyping.
Specification: once requirements have been analyzed and reviewed, it is prudent to put them into a requirements specification document. The more complex and large the number of requirements, the more there is a need to specify the requirements formally and completely.
Agreement or sign-off and acceptance: after the requirements are specified, this activity closes the requirements phase and provides a formal baseline for the requirements specifications. This agreement may be in a form of a formal document such as a contract, or an informal communication such as an email.
