Software Development Life Cycle is such a process that helps to develop and assure the quality of software. This systematic process is mainly used to design high standard software to meet up the requirements of the customers. The entire process needs to be done within a stipulated time and cost. SDLC includes the complete development of software starting from planning, creating to testing and deploying.

Benefits of SDLC

Some of the major benefits of SDLC are given below—

  • Makes a structure for planning, scheduling and estimating the project
  • Develops a framework for activities and deliverables
  • Helps to track and control a project
  • Speeds up the development and improves the relationship with clients
  • Minimizes the project risks by increasing the visibility of the project planning

Phases of Software Development Life Cycle

The complete process of SDLC includes several stages like—

1. Requirement collection and analysis:

Requirement gathering is done by the senior team members to know the possibilities of the project and analyze the issues, opportunities and directives related to the project.

2. Feasibility check:

This step is to define and document what is needed for the development of the software during the project. Usually, the feasibility check includes five types such as economic, legal, operation feasibility, technical and schedule.

3. System Design:

After feasibility studies, the gathered documents are implemented for system development which defines the entire software architecture. Mainly two types of design documents are developed in this stage such as High-level Design and Low-level Design.

4. Coding:

The immediate step after system design is coding where the developers create codes with their specific programming language. This is the most time-taking phase of the entire development life cycle.

5. Testing:  

In this phase, the functionality of the software is tested using different tools by the testing team to make sure that the entire system runs as per the client’s requirements. If any bugs are found, they are sent back to the developers to get fixed.

6. Installation:

When no bugs or defects are left in the application it becomes ready for installation. According to the project manager's feedback, the final software is introduced and examined for deployment.

7. Maintenance:

Once the customers start to use the software, usually three activities come in the picture including bug fixing, upgrade, and enhancement.

SDLC models

  • Waterfall model – It is a simple model that comes with well-defined deliverables in each phase.
  • V-shape model – This model is appropriate for smaller projects ensuring a standard product.
  • Prototype model – With this cost-effective model it is easy to understand the customers’ requirements due to the involvement of the customers.
  • Spiral models – Further enhancement can be easily done in this model.

Some Final Words

In order to make a project successful a proper software development life cycle is very important which also helps the management in the perfect way. Each of the SDLC models has its own pros and cons so it is better to choose one according to its requirements, size, skill limitations, etc.
