The waterfall model is the earliest SDLC approach that was used for software development. It divide the whole process of software development into separate phases. The outcome of one phase acts as the input for the next phase sequentially…
Problems with waterfall model
- No workable code to be tested up to the last few steps of the process.
- Changing requirements are unwelcome.
- Therefore, it will be impractical to use the waterfall model approach in such situations.
- Project scope changing too frequently will cause expensive delays and drastically change the required output.
- Test work goes in the last stage. It’s hard to troubleshoot when finding a comprehensive issue.
- All surround by specifications file, it is difficult to visualize the program in its entirety.
