2. While orientating yourselves to the company’s work practices, you observe that they in fact do not conduct a few tests that they should in order to comply with the relevant safety standard. When you inquire about this from the project manager, he dismisses it saying that those tests are really unnecessary (and takes an unreasonably long time to conduct, as well as being superfluous) and that they have managed with the other tests for so long, without any problems.”

a. you should immediately resign from the company and file a complaint with the relevant standard institution

B. you should do nothing and let the matter slide

c. although you are new to the company, and you hardly know anything about the internal processes and politics, you should insist on the company changing its work practices immediately; failing which you threaten to report the matter

d. since you are new to the company, and you are unfamiliar with the internal processes and politics, you should first find-out more about the issue and its background

3. With regard to Evolutionary development, identify the correct statement.

a. evolutionary development usually comes in two flavors; exploratory development, and throw-away prototyping

B. very large projects are natural candidates for an evolutionary development based approach

c. exploratory development is used in situations where most of the requirements are well understood in advance

d. one of the strong points of evolutionary development is that it facilitates easy project management, through the high volume of documentation it generates
