What is the project lifecycle?

Introduction

The software development lifecycle (SDLC) is a process that describes the stages involved in creating and deployng software.

Lifecycle stages

Planning

This stage involves identifying the goals and objectives of the software, as well as determining the resources and timelines required to develop it.

Design

In this stage, the software’s architecture and user interface are created, and the functional and non-functional requirements are defined.

Test

This stage involves the implementation of test-driven development (TDD). It starts by writing automated test cases based on the requirements and design of the software. The developer then writes the minimum amount of code needed to pass the test, and repeat this process until all the requirements are met.

Develop

The actual coding of the software takes place during this stage. This may involve writing code in a specific programming language or using certain development tools.

Maintain

Once the software is tested and developed, it will be integrated into the primary source code through developer efforts, usually by leveraging training environments to detect further errors or defects.

Deploy

The final stage is deployment, where the software is made available to users. This may involve installing the software on individual computers or deploying it to a server for multiple users to access.
