Software Development Life Cycle (SDLC)

Software Development Life Cycle (SDLC) is a process that outlines the different stages that are involved in developing software. The SDLC process typically consists of the following stages:

  1. Planning: In this stage, the objectives of the project are defined, the feasibility of the project is assessed, and the resources required for the project are estimated.
  2. Requirements Gathering and Analysis: In this stage, the software requirements are identified and analyzed. This involves understanding the needs of the users, the business requirements, and any technical requirements that the software must meet.
  3. Design: In this stage, the software architecture is designed, including the overall structure, the user interface, and the database design. The software design must take into account the software requirements identified in the previous stage.
  4. Development: In this stage, the actual development of the software is carried out. The software code is written and the software is tested to ensure that it meets the design specifications and software requirements.
  5. Testing: In this stage, the software is tested to identify and correct any errors or defects. This involves testing the software at various levels, including unit testing, integration testing, and system testing.
  6. Deployment: In this stage, the software is released to the production environment. This involves installing the software, configuring the environment, and ensuring that the software is ready for use.
  7. Maintenance: In this stage, the software is maintained to ensure that it continues to meet the user’s needs. This involves fixing bugs, updating the software, and adding new features as required.

The SDLC process provides a structured approach to developing software and ensures that the software meets the user’s needs, is of high quality, and is delivered on time and within budget.
