Software Development Life Cycle

 Software Development Life Cycle :  

                                                                It is step by step procedure to develope a sofware.

Another Definition 

A system development life cycle or SDLC is essentially a project management model. It defines different stages that are necessary to bring a project from its initial idea or conception all the way to deployment and later maintenance.

SDLC is a systematic process for building software that ensures the quality and correctness of the software built. SDLC process aims to produce high-quality software that meets customer expectations. The system development should be complete in the pre-defined time frame and cost. SDLC consists of a detailed plan which explains how to plan, build, and maintain specific software. Every phase of the SDLC life Cycle has its own process and deliverables that feed into the next phase. SDLC stands for Software Development Life Cycle and is also referred to as the Application Development life-cycle.

The software development process is normally long and tedious. But project managers and system analysts can leverage software development life cycles to outline, design, develop, test, and eventually deploy information systems or software products with greater regularity, efficiency, and overall quality.

The Software Development Life Cycle (SDLC) is a structured process that enables the production of high-quality, low-cost software, in the shortest possible production time. The goal of the SDLC is to produce superior software that meets and exceeds all customer expectations and demands. The SDLC defines and outlines a detailed plan with stages, or phases, that each encompass their own process and deliverables. Adherence to the SDLC enhances development speed and minimizes project risks and costs associated with alternative methods of production.


7 Basic Stages of the System Development Life Cycle 

There are seven primary stages of the modern system development life cycle. Here’s a brief breakdown:
  1. Requirement of analysis
  2. Feasibility/ Planning
  3. Design/Pre-Preparation/Prototyping
  4. Coding
  5. Testing
  6. Installation
  7. Maintenance
