What is SDLC?

• SDLC stands for Software Development Lifecycle.
• It is defined as the sequential steps of process taken to produce a software product.

• Software development process is divided into different stages.

Plan/Analyze->Gathering Requirements.
Design->Completing Project Specification
Develop->Completing Product Development
Test->Completing testing of the product
Release/Deploy->Go-live

• SDLC plays a key role in describing the activities taking place in each stage of software development.

• SDLC kick starts right from the capability of the product is conceived to the production.

• In other words,SDLC is initiated from requirements phase to deployment phase.
• SDLC implies the associations and relationships between project phases.The project phases are including exit and entry criteria,reviews,feedback mechanisms,walkthroughs,milestones,deliverables and baselines

Uses of SDLC:

• Guide to testers,project managers,business analysts,developers and other people involved in software development.
• It avoids discrepancies in software development.

• It minimizes the old code-and-fix-process.

Common SDLC Models:

• Water fall model
• Incremental/Overlapping Model
• Prototyping Model
• Spiral Model
