FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -According to Royce’s paper, Waterfall is ideal for smaller, internal projects but is generally quite flawed when it comes to larger, more complex projects. This method is also not suitable for other longer-term projects.

Detailed explanation-2: -Disadvantages of waterfall model Once an application is in the testing stage, it is very difficult to go back and change something that was not well-thought out in the concept stage. No working software is produced until late during the life cycle. High amounts of risk and uncertainty.

Detailed explanation-3: -The Failings of Waterfall Waterfall uses the theory that what you want at the beginning is what you get at the end so there is little, if any room, for significant changes in direction. Being an inflexible model which does not provide for feedback, it is difficult to highlight new requirements and thus change course.

Detailed explanation-4: -Which of the following statements about the waterfall methodology is true? The waterfall methodology moves sequentially from planning, to analysis, to design, to implementation. The waterfall methodology is iterative (i.e., cyclical)–several rounds of planning, analysis, design, and implementation occur.
