What are the main challenges of the Waterfall model in software development?

The Waterfall model faces several challenges, including inflexibility to changes, late testing phases, and difficulty in accommodating user feedback.

Can you elaborate on why inflexibility is a problem?

Inflexibility means that once a phase is completed, going back to make changes is costly and time-consuming, which can lead to project delays.

What about late testing phases? How does that affect the project?

Late testing can result in discovering critical issues only at the end of the development cycle, making it harder to fix them without significant rework.

Are there any alternatives to the Waterfall model?

Yes, alternatives like Agile and Scrum allow for more flexibility and iterative development, which can better accommodate changes and user feedback.

What industries typically use the Waterfall model?

The Waterfall model is often used in industries like construction, manufacturing, and some areas of software development where requirements are well-defined.
