Which phase of the software development life cycle details the business requirements for an app?

• A. Design
• B. Requirement Analysis
• C. Testing
• D. Deployment

Answer: (B)

The main concept here is how business needs are captured and translated into a plan for building the software. In the Requirements Analysis phase, stakeholders’ needs, constraints, and what the business expects the app to achieve are gathered, clarified, and documented. This results in a formal set of requirements that define the scope and serve as the blueprint for everything that follows, guiding design, development, and testing so the final product actually delivers the intended business value.

Design focuses on turning those requirements into a concrete plan for implementation—architecture, components, and how the solution will be built. Testing checks whether the developed product meets the documented requirements. Deployment is the release of the product to users.
