a. What is the name of this model?

b. Provide one advantage and one disadvantage of this model.

Requirements definition

System & software design

Implementation and unit testing

2. (20 pts total) Short answer:

a. Write an example user story.

b. What is the difference between these three kinds of testing in XP: unit tests, integration tests, and

acceptance tests?

c. A library check-out system is intended for use in the library building. It is used for book

checkout and searches. Checkout is done as with the OSU library, in which there is a person behind

a counter who actually performs the checkout procedure for the student who wants the book, but

just like in the OSU library, students can perform searches themselves. The system also generates

statistical reports about loan frequency, delinquent borrowers, books on order, available funds for

new books, etc.

For this system, all I want you to do is to list all the stakeholders.

d. Provide one example of a fit criterion and explain what makes it a fit criterion.

Important: If you need to make any assumptions about any of these problems, write them down on the test so that we know what you’re thinking!

other tasks take exactly the durations in the table. Do we know that the project’s final completion

date will be late? Why or why not?

5. (15 pts) Sommerville mentions 3 possible types of risk management strategies.

a. Give an example of one risk in a software project.

b. For your example risk, explain a strategy you as team leader will adopt in the way of risk

management for this risk and say which of the 3 types your strategy exemplifies.

6. (10 pts) Suppose the company needs your project to be completed by a team of 3 people by

December 1. No more people and no more time are possible. You are leader of an XP team. Say

what option(s) is/are viable for your team in this situation if it appears that you cannot make the

deadline. Your answer should include convincing reasoning that the options you give are indeed the

only options that are viable.

(Hint: According to XP, there are 4 variables in any software project. This problem is basically to

identify what variable(s) you can/should manipulate.)
