• This model is costly.
• It has poor documentation because of continuously changing customer requirements.
• There may be too much variation in requirements.
• Customers sometimes demand the actual product to be delivered soon after seeing an early prototype.
• There may be sub-optimal solutions because of developers in a hurry to build prototypes.
• Customers may not be satisfied or interested in the product after seeing the initial prototype.
• There is certainty in determining the number of iterations.
• There may be incomplete or inadequate problem analysis.
• There may increase the complexity of the system.
