Software Development Life Cycle (SDLC)

 The first step in the Software Development Life Cycle (SDLC) is typically the "Requirements Gathering" or "Requirement Analysis" phase. During this phase, the project team works closely with stakeholders, including clients, end-users, and other relevant parties, to gather and document detailed requirements for the software system.

 The goal of this phase is to understand the needs and expectations of the users and stakeholders, and to define the scope of the project. This involves identifying the functional and non-functional requirements, constraints, and any other relevant information that will guide the development process.

Software Development Life Cycle (SDLC):

1. Identification of Stakeholders:

   Identify and involve all relevant stakeholders, including clients, end-users, project managers, developers, and any other individuals or groups affected by the software.

2. Define Project Objectives:

   Clearly outline the goals and objectives of the software project. This involves understanding the problem the software aims to solve or the opportunity it aims to exploit.

3. Gather Initial Requirements:

    Conduct initial meetings, interviews, surveys, or workshops to collect high-level requirements. These requirements can be broad and might not be detailed at this stage.

4. Create a Project Vision Document:

   Develop a high-level document that captures the overall vision, purpose, and scope of the software project. This document helps in aligning all stakeholders and team members.

5. Feasibility Study:

   Evaluate the technical, economic, legal, operational, and scheduling feasibility of the proposed project. This step helps in determining whether the project is viable and worth pursuing.

6. Prioritize Requirements:

    Work with stakeholders to prioritize requirements based on their importance and impact on the project goals. This step helps in making informed decisions when resources are limited.

7. Create a Requirements Document:

    Document all gathered requirements in detail. The document should include functional requirements (what the system should do) and non-functional requirements (qualities the system should have, like performance, security, etc.).

8. Review and Validate Requirements:

    Conduct thorough reviews of the requirements document with stakeholders to ensure that all aspects are captured accurately. Validation helps in avoiding misunderstandings and scope creep later in the development process.

9. Get Sign-off:

    Obtain formal approval or sign-off from key stakeholders, indicating their agreement with the documented requirements. This sign-off serves as a baseline for the rest of the SDLC phases.

Once the Requirements Gathering phase is completed, the project can move on to the subsequent phases such as system design, implementation, testing, deployment, and maintenance, following the established roadmap provided by the requirements document.
