The Importance of Design Phase in Software Development Life Cycle (SDLC)

What is the software development life cycle (SDLC) methodology phase that comprises developing the preliminary and detailed configurations, including how the system will meet functional requirements?

a. Planning and Requirements Definition

b. Operations and Maintenance

c. Implementation

d. Design

Answer:

The software development life cycle (SDLC) methodology phase that comprises developing the preliminary and detailed configurations, including how the system will meet functional requirements is called the Design phase (option d).

During the design phase of the SDLC, the system's architectural, logical, and physical design is created. This phase is crucial as it determines the system's functionality, performance, security, and maintainability. Additionally, the user interface of the system is also designed during this phase.

Once the design phase is completed, the development team can proceed to the next phase, which is the implementation phase. In the implementation phase, the actual coding and programming of the system take place based on the designs created in the previous phase. Proper planning and detailed design in the design phase can significantly impact the quality and success of the software product.

Therefore, it is essential for software development teams to dedicate sufficient time and resources to the design phase of the SDLC. By focusing on creating comprehensive and well-thought-out designs, developers can ensure that the final product meets the requirements and expectations of stakeholders.
