Question

Which of the following is not a phase or activity of requirement engineering in context of software engineering?
1. Feasibility study
2. Requirements elicitation and analysis
3. Requirement validation
4. Component specification

Answer 1

Correct Answer - Option 4 : Component specification

The phases in SDLC are −

• Requirement Gathering and analysis − All possible requirements of the system to be developed are captured in this phase and documented in a requirement specification document.
• System Design – The system design helps in specifying hardware and system requirements and helps in defining the overall system architecture.
• Implementation − With inputs from the system design, the system is first developed in small programs called units, which are integrated in the next phase. Each unit is developed and tested for its functionality, which is referred to as Unit Testing.
• Integration and Testing − All the units developed in the implementation phase are integrated into a system after testing of each unit. Post integration the entire system is tested for any faults and failures.
• Deployment of system − Once the functional and non-functional testing is done; the product is deployed in the customer environment or released into the market.
• Maintenance − There are some issues that come up in the client environment. To fix those issues, patches are released

Hence the Component Specification is not the part of the Software lifecycle.
