Decoding the Advantages of Software Development Lifecycle

The Software Development Lifecycle is a systematic process for building software that ensures the quality and correctness of the software built. SDLC is a structure followed for software development. It consists of a detailed plan describing how to develop, maintain and replace specific software. The life cycle defines a methodology for improving the quality of software and the overall development process.

Purpose of SDLC is to deliver a high-quality product which is as per the customer’s requirement. SDLC has defined its phases as

• Requirement gathering

• Designing

• Coding

• Testing

• Maintenance

It is important to adhere to the phases to provide the Product in a systematic manner. SDLC works by lowering the cost of software development while simultaneously improving quality and shortening production time. SDLC achieves these apparently divergent goals by following a plan that removes the typical pitfalls to software development projects.

Some of the reasons why SDLC is important in Software Development are as follows:

• It provides visibility of a project plan to all the involved stakeholders.
• A deterministic “definition of done” that can be used to confirm whether a step is truly complete
• It gives a review at the end of each phase so managers can track their progress and see if they’re on target with their goals.
• It helps us to avoid project risks and allows to track and control the project.
• It doesn’t conclude until all the requirements have been achieved.

SDLC is considered a phased project model that defines the organizational, personnel, policy, and budgeting constraints of a large scale systems project. The scalability allows to make changes and add new functionality even at the relatively late stages. The project manager can properly manage a project if deliverables are completed on time and within the budget.
