Waterfall Model in SDLC

Waterfall Model in SDLC

The systems development life cycle illustrates the end-to-end process for developing and maintaining software. Gregory (2020) discussed SDLC from the waterfall model perspective.

1. Discuss each phase of the waterfall model of SDLC.
2. Identify other models similar to a waterfall.
3. Which is the most important phase of SDLC, and what are common problems that you can face in the process of SDLC?

Waterfall Model in SDLC

In this paper, I will provide an in-depth discussion of the Waterfall Model within the Systems Development Life Cycle (SDLC), describing each phase, identifying other similar models, and evaluating the most important phase of SDLC. Additionally, I will explore common problems encountered throughout the SDLC process.

1. Phases of the Waterfall Model:

The Waterfall Model, one of the oldest and most traditional approaches to software development, follows a linear and sequential flow, with each phase acting as a prerequisite for the next. Below are the phases of the Waterfall Model:

1. Requirements Gathering and Analysis:

   • Description: This is the first phase where the system’s requirements are defined in detail. It involves collecting data from stakeholders and understanding user needs to create a comprehensive requirements specification.
   • Objective: To document clear and concise functional and non-functional requirements that will serve as the basis for the system’s design.

2. System Design:

   • Description: In this phase, the system’s architecture and design are created based on the requirements gathered in the previous phase. It involves both high-level design (architecture) and detailed design (component-level design).
   • Objective: To define system models, specifications, data flow diagrams, and overall system structure.

3. Implementation (Coding):

   • Description: After the system design is complete, the development team starts building the system by writing code and developing components according to the design specifications.
   • Objective: To produce the actual system based on the approved design, using the required programming languages and tools.

4. Testing:

   • Description: The testing phase is where the system undergoes rigorous testing to ensure it works as intended and meets the requirements outlined in the earlier phases. This includes unit testing, integration testing, system testing, and user acceptance testing (UAT).
   • Objective: To detect and correct defects, ensuring the system performs as expected under all scenarios.

5. Deployment:

   • Description: In this phase, the system is…
