Advantage
1.This documentation ensures that system requirements can be traced back to stated business requirements.
2.It produces many intermediate products that can be reviewed to see whether they meet the user’s needs and conform to standards. These can be further worked on if they require tweaks to be made, ensuring that the business gets exactly what it needs.

Disadvantage
1.Users cannot easily review intermediate products and evaluate whether a particular product (e.g., data flow diagram) meets their business requirements.
2.Documentation is expensive and time-consuming to create. It is also difficult to keep current.
