This technique is adopted from sociology. These meta-models are capable of maintaining the trace information through relations. The industry has emphasized on the requirement management system for handling requirements more effect ively and are documented, analyzed, traced, agreed upon, monitored, versioned and prioritized [31]. Requirements engineering plays a crucial role in coordinating with different stakeholders/customers needs and helps the developers to develop software's which fulfill almost all the requirements of the stakeholders/customers. This metric enables a software engineer to measure the complexity before actual design and implementation and choose strategies that are appropriate to the software complexity degree, thus saving on cost and human resource wastage and, more importantly, leading to lower maintenance costs. The input measures can be the size and volatility of the requirements. They are − Processes; Products; Resources; All of these entities have internal as well as external entities. Automated Requirements Tools. Database record identification and symbolic identification can also be used for numbering the requirements. In requirements engineering (RE), although to lesser extent, metrics have been proposed to aid in the RE process. Unlike model or code-derived test cases, these tests are immediately traceable to high-level requirements. are helpful in measuring requirements metrics. It is very challenging for software developers and testers to maintain trace, particularly during the evaluation and upgrading phases of development. is measured. deliver the right solution on time and within budget with proper Requirements metrics such as volatility, traceability, size and completeness are used to measure requirements engineering phase of software development lifecycle. 5.2.
