b. Not able to support the development of reusable components.

c. Dependent on object technologies for support.

d. Not cost effective by known quantifiable software metrics.

25. Describe the phases of the prototyping model for software development?

Answer:Requirements are gathered by having the customer and developer meet and identify whatever objectives and requirements they can. Quick design follows, focusing on representation of the software that will be visible to the customer. A prototype is constructed by the developer and evaluated by the customer and used to refine the requirements. Iteration occurs and the prototype is tuned to satisfy the customer's needs.
