Requirements Engineering Process in Software Engineering

Front

What is Requirements Engineering?

Back

Requirements Engineering is the process of identifying, eliciting, analyzing, specifying, validating, and managing the needs and expectations of stakeholders for a software system.

Front

What are the main steps in the Requirements Engineering process?

Back

The main steps are: 1. Feasibility Study 2. Requirements Elicitation 3. Requirements Specification 4. Requirements Verification and Validation 5. Requirements Management.

Front

What is a Feasibility Study in Requirements Engineering?

Back

A Feasibility Study assesses the project's viability in terms of Technical, Operational, Economic, Legal, and Schedule feasibility.

Front

What techniques are used for Requirements Elicitation?

Back

Techniques include interviews, surveys, focus groups, observation, and prototyping.

Front

What is Requirements Specification?

Back

Requirements Specification is the process of documenting the requirements in a clear, consistent, and unambiguous manner.

Front

What are Functional Requirements?

Back

Functional Requirements describe what the software system should do, specifying the functionality it must provide.

Front

What are Non-Functional Requirements?

Back

Non-Functional Requirements describe how well the software system should perform, specifying quality attributes like performance and security.

Front

What is the difference between Verification and Validation in Requirements Engineering?

Back

Verification checks if the requirements are correctly specified, while Validation ensures that the requirements meet stakeholder needs.

Front

What is Requirements Management?

Back

Requirements Management involves analyzing, documenting, tracking, prioritizing, and controlling changes to requirements throughout the software development lifecycle.

Front

What are some advantages of the Requirements Engineering process?

Back

Advantages include ensuring software meets stakeholder needs, identifying issues early, improving communication, and providing a clear description of requirements.
