Difference between SDLC and STLC | SDLC vs STLC

Definition

 it is a systematic approach to develop a software.

The process of testing a software in a well planned & systematic way

Requirements Gathering

Gathering of requirements is carried out by the BA (Business Analyst) where the development team will analyses the requirements right from the design architecture to the coding into perspective. 

Here QA Team, uses requirements gathering for testing, review, and analysis of the requirements.

Design Phase

Here Technical architect comes whose function is to ensure that high level and low designs of the software are met.

Soetimes, the BA (business analyst) also comes in here to create a user interface design for the application. 

Here Test architect acting as the lead manager in doing the test planning and the identification of the high level testing points. 

coding or development phase

Here actual development which refers to coding occurs (Development Team) and this is based on the design architecture. 

 

Here QA Team focus on writing the detailed test design activities (Preparation Test scenarios and Test cases).

Testing phase

In this phase, actual testing of the developed code. Within this phase, different levels of testing will be done. 

Here test execution too done in addition to reporting any errors/defects that are found.  

Here manual reporting, automation, and testing is performed to ensure that the developed code functions as it should.

Retesting and regression

testing are also performed within this stage. 

Deployment phase

Deploys applications that have passed over last four stages

This will be the final testing and implementation stage.

Testing is done & a final report is prepared.

Maintenance phase

It features post production and deployment support and follow-up with enhancements as they continue to be developed.

Features updates and maintenance of test plans, and testing and support of test phases, as well as enhancements as part of maintenance.
