Which SDLC stage focuses on defining the project scope and purpose?

The stage of the Software Development Life Cycle (SDLC) that focuses on defining the project scope and purpose is the Planning stage. During this phase, key activities include determining the objectives for the project, identifying stakeholder needs, and outlining the project’s goals. This foundational work is essential to ensure that everyone involved has a clear understanding of what the project aims to achieve and what constraints may be in place.

Establishing the project scope helps prevent scope creep during later stages of development, as it clearly delineates what is included in the project and what is not. In addition, outlining the project’s purpose provides motivation and context for the project team and stakeholders, ensuring that the end product aligns with the initial objectives and expectations. This clarity is vital for creating a focused roadmap for the subsequent phases of the SDLC, where detailed planning, design, and implementation take place.
