Software Development Life Cycle

SDLC is a cost-effective and time-saving process used by developers to build and design robust yet eminent software. It mitigates the risk factor for projects by planning forward so that the product meets the customer’s expectations.

This approach is a series of steps that divides the process of software development into tasks. Once the whole lengthy process is divided into minimal tasks, it becomes easier to comprehend, and they can be easily assigned, completed, and then evaluated for results.

SDLC has a range of benefits:

• Provides visibility to software developers
• Gives control over the project to business owners
• Makes sure that the goal is achieved on time and the task is completed on time.
• Ensures that the budget or the deadline is not exceeded.
• Customer satisfaction is ensured at all costs.
