JNTU B.Tech III SOFTWARE PROJECT MANAGEMENT Previous Question Paper (January/February - 2023 - R18)

The design phase in the Waterfall model follows the requirement analysis phase and focuses on translating the software requirements into a structured system architecture. During this stage, developers define the system's overall structure, data design, interface design, and procedural design, creating a blueprint that guides the subsequent implementation phase.

The requirements phase is the foundation of the software development lifecycle, as it defines the scope, functionality, and constraints of the system. Its importance lies in the following key areas:

• Cost Reduction: Identifying errors or ambiguities during the requirements phase is significantly cheaper than fixing them during later stages like coding or testing, where the cost of change increases exponentially.
• Project Alignment: It ensures that all stakeholders, including clients and developers, share a common understanding of the project goals, preventing scope creep and misalignment between user expectations and the final product.
• Basis for Planning: Accurate requirements serve as the primary input for project estimation, scheduling, resource allocation, and the design of test cases, ensuring the project remains on track and within budget.
