Why is the waterfall model of software development often criticized?

1. It allots too much time for testing

2. It focuses solely on end-user training

3. It does NOT consider software designers' work practices

4. It encourages frequent changes in scope

The correct answer is: It does NOT consider software designers' work practices

The waterfall model of software development is often criticized for its rigid, linear structure, which does not take into account the work practices of software designers throughout the development process. This model proceeds through a series of sequential phases—requirements, design, implementation, verification, and maintenance—without revisiting previous stages once they are completed. As a result, it can overlook the iterative and sometimes collaborative nature of software development that many designers utilize to adapt to new information or evolving requirements. This inflexibility can lead to miscommunication, unmet requirements, and an inability to incorporate user feedback once the design has commenced, ultimately affecting the quality and relevance of the final product. Understanding this criticism is important for professionals in healthcare technology, as adapting development practices to fit real-world workflows can greatly enhance the usability and effectiveness of health information systems. Rather than enforcing a strict adherence to initial plans, successful development approaches often integrate iterative and user-centered methodologies that align better with how teams naturally work.
