Detailed explanation-1: -The waterfall model is most commonly used in software engineering and product development, less often – in other projects and industries. Employ the waterfall model only if your project meets the following criteria: All the requirements are known, clear, and fixed. There are no ambiguous requirements.
Detailed explanation-2: -Costly And Inflexible One of the main disadvantages of the waterfall model is that once it’s structured with the relevant information, it’s practically impossible to make changes. Returning to a previous phase to make alterations is extremely difficult.
