  • Discuss the advantages and disadvantages of the waterfall approach to system development.

The Waterfall approach to system development is a linear, sequential method that involves distinct phases of development, such as requirements gathering, design, implementation, testing, and maintenance.

Advantages of the Waterfall Approach:

  1. Clear Deliverables: The Waterfall approach provides clear deliverables at the end of each phase, making it easy to track progress and ensure that the project is on schedule.
  2. Structured Process: The Waterfall approach provides a structured process that helps ensure that the necessary steps are taken in a specific order, reducing the risk of missing critical tasks or steps.
  3. Better Planning: The Waterfall approach requires extensive planning in the early phases, which helps to identify potential problems early on and to develop a comprehensive plan for solving them.
  4. Improved Documentation: The Waterfall approach requires comprehensive documentation, which helps to ensure that everyone involved in the project is on the same page and that the project can be easily handed off to another team if needed.

  2. Time-consuming: The Waterfall approach can be time-consuming, as each phase must be completed before the next one begins. This can lead to longer project timelines and higher costs.
  3. Lack of Feedback: The Waterfall approach does not allow for feedback from users until the testing phase, which can be too late to make significant changes. This can lead to a product that does not meet user needs.

In reference to an organization’s buy versus build decision, there are pros and cons to each approach.

  1. Reduced Development Time: Buying a solution can save time as the solution is already developed and available for immediate use.
  2. Lower Cost: Buying a solution can be less expensive than developing one from scratch, as the cost of development is spread across multiple customers.
  3. Access to Expertise: When buying a solution, organizations have access to
