Software Development Life Cycle(SDLC)

Software Development Life Cycle(SDLC)

A Software Development Life Cycle (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.

Phases of Software Development Life Cycle (SDLC)

Software Development Life Cycle(SDLC)

1. Planning

The first stage of new software development will gather all relevant information from stakeholders and analyze this information to determine what will be feasible.

This includes compiling requirements, studying user personas, and agreeing on the product’s purpose. During this phase, the team will also discuss the opportunities and risks of pursuing the project. This is why Software Testing Help refers to this phase as both requirements gathering and analysis.

2. Analysis

The analysis stage includes gathering all the specific details required for a new system as well as determining the first ideas for prototypes.

Developers may:

  • Define any prototype system requirements
  • Evaluate alternatives to existing prototypes
  • Perform research and analysis to determine the needs of end-users

3. Design

The next phase is about to bring down all the knowledge of requirements, analysis, and design of the software project. This phase is the product of the last two, like inputs from the customer and requirement gathering.

4. Implementation

Implementation/Coding starts once the developer gets the Design document. The Software design is translated into source code. All the components of the software are implemented in this phase.

5. Testing & Integration

After the code is generated, it is tested against the requirements to make sure that the products are solving the needs addressed and gathered during the requirements stage. During this stage, unit testing, integration testing, system testing, acceptance testing are done.

Once the software is certified, and no bugs or errors are stated, then it is deployed. Then based on the assessment, the software may be released as it is or with suggested enhancement in the object segment. After the software is deployed, then its maintenance begins.

6. Maintenance

After the deployment of a product on the production environment, maintenance of the product i.e. if any issue comes up and needs to be fixed or any enhancement is to be done is taken care by the developers.

Summary

Software Development Life Cycle(SDLC) gives organizations a systematic, step-by-step approach to developing successful software from gathering the initial requirements for a new product. We’ll teach you how to employ SDLC by maintaining a mature product on the market.
