Compare and contrast waterfall and iterative development models. Describe the strengths and weaknesses of each. For each of the following two scenarios, describe the better of the two development models and why it would be:

1. Your company is developing a product using new, unproven technology. As it is new territory for both the company and the industry, there is much ambiguity in the . requirements and the scope of the final project.

2. A "Line Extension" project builds a significant set of new features onto an existing project. The features come from detailed customer feedback and there is very little gray area in what is needed or how to implement it. The customer has basicallysaid"You know what we want, go ahead and build it, and call us when it is done".
