What happens in the requirement analysis phase of SDLC?
Requirement analysis is the most critical stage in SDLC. It is performed by the senior members of the team. During this phase, the development team works closely with the stakeholders, end-users, and customers to understand their needs and requirements.
The gathered information is subsequently utilized for
devising the fundamental project strategy and performing an assessment of the
product's viability in terms of economic, operational, and technical aspects.
The requirement analysis phase is critical as it helps
to ensure that the software is designed and developed to meet the needs of the
stakeholders, end-users, and customers. It also helps to identify potential
issues early in the development process, which can save time and money later
on.
- Gathering Requirements: This involves identifying the stakeholders, defining the problem, and collecting information about the requirements of the software. The development team conducts interviews, surveys, and focus groups to collect this information.
- Analyzing
Requirements: The gathered requirements are then analyzed to identify the
key features and functionalities that the software should have. This step
also involves identifying any potential risks or challenges that may arise
during the development process.
- Prioritizing
Requirements: Once the requirements have been analyzed, they are
prioritized based on their importance and feasibility. This helps the
development team to focus on the most critical requirements first.
- Creating
Requirement Specifications: This involves creating a document that
outlines the requirements of the software in detail. The document includes
functional and non-functional requirements, user interface design, and
other specifications.
- Reviewing
and Approving Requirements: The requirement specifications document is
reviewed by stakeholders and approved once everyone is satisfied that the
requirements have been accurately captured.
