What is the Software Development Life Cycle?

Software Development Life Cycle is a process used by the software industry to design, develop, and test good-quality software. SDLC includes all the phases of software development from planning to retirement of the software. The life cycle helps to properly phase the planning, implementation, maintenance, and development of the software.

What is the Need for Software Development Life Cycle?

SDLC is essential to create a disciplined and systematic phase while developing any software. The systematic phases help in increasing the quality and precision of the product software. Software Development Life Cycle divides the process of development into small phases which makes it easier for everyone to keep track of their task.

SDLC is also beneficial to avoid any chaos and misunderstanding between the team members. 

7 Stages of Software Development Life Cycle

Software Development Life Cycle is divided into 7 different phases to make the software development process more efficient. The 7 phases of SDLC include:

  1. Planning Phase
  2. Analysis Phase
  3. Design Phase
  4. Development Phase
  5. Testing Phase
  6. Implementation Phase
  7. Maintenance Phase
