Software Development Life Cycle (SDLC), SDLC PHASES, Importance of SDLC

What is Software Development Life Cycle (SDLC)?

Software Development Life Cycle (SDLC) is a structured software development process that ensures the value and correctness of the built software.

SDLC Phases-
The SDLC process divided into the following phases:

Phase 1:
Requirement Analysis: Communicating to collect and document project specifications with stakeholders and users. This phase contain requirements gathering, project initiation, estimating, scheduling, tracking, SRS documentation.

Phase 2:
Design: Building a software system architecture and element based on software requirements specification (SRS) Document. This phase contain mainly system architecture.

Phase 3:
Coding: Development of the software by the development team using a programming language.

Phase 4:
Testing: The software developed is thoroughly tested and any bugs found are assigned to developers to fix them.

Phase 5:
Deployment: After the product is tested, the production team preparing the software to run and live in a specific environment.

Phase 6:
Maintenance: The product is updated and maintained after it has been introduced to the market.

Importance of the SDLC for developing a software system:

1. It provides a framework for planning, scheduling, and estimating projects.
2. It provides a basis for a standard collection of projects and deliverables.
3. It is a tool to manage and control projects.
4. It increases project development visibility for all interested.
5. It stakeholders in the construction phase.
6. It increased and boosted the speed of development.
7. It improved connections with clients.
8. It allows you to reduce project risk and efficiency plan for project management.
