University of California - IrvineSoftware Engineering

A midterm exam for the course ICS 52 - Introduction to Software Engineering. The exam consists of 11 questions that cover topics such as software quality, software process models, and requirements engineering. The questions require students to define and describe software quality attributes, explain how process models promote software quality, and identify processes in requirements engineering. The exam also includes multiple-choice questions that test students' knowledge of software quality definitions and the waterfall model. The exam is from Winter, 2011.

1. (12 points.) Name and define (in the context of software engineering) one
desirable software quality, other than “maintainability” and “correctness,”
discussed in lecture or the textbook. Read question 2 before you answer this
question.
See p. 124
2. (15 points.) Select one software process model described in lecture or the
textbook, and describe how following that model promotes the software quality
you selected in question 1. Be quite specific.
For full credit, we looked for an answer that made a strong and
logical connection between the process model and the quality.

  1. (15 points.) Select one software process model described in lecture or the textbook, and describe how following that model promotes the software quality you selected in question 1. Be quite specific.

For full credit, we looked for an answer that made a strong and logical connection between the process model and the quality.

  1. (15 points) According to the textbook, several processes are part of requirements engineering. One of them is Requirements specification: “Once the problem is understood, it has to be described.” Name and describe one of the other processes in requirements engineering that the textbook lists.

See p. 218.

Requirements elicitation: the requirements engineer gains expertise and an internal model of the desired system. Building a conceptual model of the Universe of Discourse.

Requirements validation and verification: ascertain that correct requirements are stated (validation) and that these requirements are stated correctly (verification).

Requirement negotiation: resolving conflicts or setting priorities.

  1. (4 points) The textbook says that “Viewing software engineering as a branch of engineering is problematic.” Why does the textbook suggest that software engineering is not best viewed as a branch of engineering? A. Software engineering does not usually deal with a well-defined problem. B. In software engineering the product is developed using a number of phases. C. In software engineering scientific techniques are used in creative ways. D. In mature engineering disciplines, such as bridge design, accidents sometimes occur. E. Software engineering involves products with multiple versions.
  2. (4 points) Which of the following is the best definition of “software architecture”? A. Top-level decomposition of a system into major components, together with a characterization of how these components interact. B. The blue print of a system, giving the user a precise definition of the eventual functionality. C. A collection of system components that interact in a pleasing and attractive manner. D. The software equivalent of “cuisine” for cooking or “style” for music: a characterization of elements that are historically and culturally related. E. The hardware platform on which the software is run.
  3. (4 points) The term “shrink wrapped” software was used in lecture, as a term to indicate A. Software that is sold to the general public. B. Software that can be returned if it is not satisfactory. C. Not actually the software, but the medium (e.g. a CD) on which it is distributed. D. Software that is a “black box,” that is, not understandable by the typical consumer. E. All of the above.
  4. (4 points) Which of the following is not an Extreme Programming practice? A. Prototyping (an early working model is created in order to assess usability). B. 40-hour week (the team works only 40 hours per week). C. Pair programming (all code is written by two programmers at one machine). D. Unit tests (programmers continuously write unit tests). E. Small releases (a simple system is first realized, then other versions are released in short cycles).
  1. (4 points) In the write-up of the on-line wine store, the requirements are described as “an overview.” The write says that a real-world commercial application would also have A. an accompanying design document discussing the database design, screen layouts, and information flows. B. a test-plan for each class and method. C. a prototype to identify and resolve risk. D. a companion document listing the programming staff and each person’s responsibilities. E. a statement of architectural style (SAS).
  2. (4 points) The textbook discusses Garvin’s five definitions of software quality, each of which captures a different perspective. Which type of software quality relates to attributes of the software? A. Product-based definition B. Manufacturing-based definition C. Value-based definition D. Transcendent definition E. User-based definition
  3. (4 points) Why is the waterfall model called an “ideal” model? (Choose the best answer.) A. It represents the software process as having no imperfections. B. It is the best in practice. C. It is an descending model. D. It is the most likely to result in a successful software system. E. It was the first software process model published.
