Software Development Life cycle
The software development life cycle (SDLC) is a process that software developers follow to design, develop, and test software. This approach to software development involves planning, creating, testing, and maintaining software throughout its entire lifecycle.
These are the typical phases that an SDLC goes through;
Stage 1: Planning and Requirement Analysis
Stage 2: Defining Requirements
Stage 3: Designing the Product Architecture
Stage 4: Building or Developing the Product
Stage 5: Testing the Product
Stage 6: Deployment in the Market and Maintenance
1.
Planning and Requirement Analysis: In this
stage, the project team identifies the goals and objectives of the project and
determines the resources and timeline needed to complete the project. The
project requirements are also analyzed, and a plan is created to meet those
requirements.
2.
Defining Requirements: In this stage, the
requirements are further refined, and the project team creates a detailed list
of what the product should do and how it should behave. This is done in close
consultation with stakeholders to ensure that everyone is on the same page
regarding what the product should be able to do.
3.
Designing the Product Architecture: In
this stage, the software architecture is designed, and the project team
determines how the different components of the software will work together.
This includes creating a detailed plan for the user interface, data storage,
and communication between different parts of the system.
4.
Building or Developing the Product: In
this stage, the actual development of the software takes place. The software
code is written, and the different components are put together to create a
working product. This is the stage where most of the time and effort in the
software development life cycle is spent.
5.
Testing the Product: In this stage, the software
is tested to ensure that it meets the requirements set out in the previous
stages. This includes both manual testing and automated testing to ensure that
the software behaves as expected and can handle different types of inputs and
scenarios.
6.
Deployment in the Market and Maintenance:
In this stage, the software is deployed to the market, and users can start
using it. The project team continues to monitor the software and make
improvements as needed to ensure that it remains up to date and can handle new
requirements or changes in the market. Maintenance also involves fixing bugs,
updating security protocols, and ensuring that the software continues to
perform as intended.
