Answer with TRUE or FALSE: (Underlined option is correct) 1. Software engineering umbrella activities are only applied during the initial phases of software development projects. True /

False

2. The best software process model is one that has been created by the people who will actually be doing the work. True / False 3. It is generally accepted that one cannot have weak software processes and create high quality end products. True / False 4. The incremental model of software development is a good approach when a working core product is required quickly. True / False 5. The prototyping model of software development is a reasonable approach when requirements are well defined. True /

False

6. In the Unified Process model requirements are determined iteratively and may span more than one phase of the process. True / False 7. In agile software process the frequent change requests from customers are discouraged. True /

False

8. In agile software processes the highest priority is to satisfy the customer through early and continuous delivery of valuable software. True / False

9. It is not possible to build software that meets the customers' needs today and exhibits the quality characteristics that will enable it to be extended tomorrow. True /

False

10. Agility is nothing more than the ability of a project team to respond rapidly to change. True / False 11. The only deliverable work product for a successful project is the working program. True /

False

12. There is no way of assessing the software quality during its development until the code is ready and can be executed. True /

False

Encircle your choice. Only one choice is correct. (Underlined option is correct) 1. Software deteriorates rather than wears out because A Software suffers from exposure to hostile environments B Defects are more likely to arise after software has been used often C Multiple change requests introduce errors in component interactions D Software spare parts become harder to order 2. The nature of software applications can be characterized by their information A complexity B content C determinacy D both b and c 3. Which of the items listed below is not one of the software engineering layers? A Process Manufacturing B C Methods D Tools 4. Which of these are the 5 generic software engineering framework activities? A communication, planning, modeling, construction, deployment B communication, risk management, measurement, production, reviewing C analysis, deg, programming, debugging, maintenance D analysis, planning, deg, programming, testing

5. Process models are described as agile because they A eliminate the need for cumbersome documentation B emphasize maneuverability and adaptability C do not waste development time on planning activities Page 2 of 4

D

make extensive use of prototype creation

6. The linear sequential model of software development is A A reasonable approach when requirements are well defined. B A good approach when a working program is required quickly. C The best approach to use for projects with large development teams. D An old fashioned model that cannot be used in a modern context. 7. Evolutionary software process models A Are iterative in nature B Can easily accommodate product requirements changes C Do not generally produce throwaway systems D All of the above 8. The spiral model of software development A Ends with the delivery of the software product B Is more chaotic than the incremental model C Includes project risks evaluation during each iteration D All of the above 9. Which of the following traits need to exist among the of an agile software team? A Competence B Decision-making ability C Mutual trust and respect D All of the above 10. What are the four framework activities found in the Extreme Programming (XP) process model? A analysis, design, coding, testing B planning, analysis, design, coding C planning, analysis, coding, testing D planning, design, coding, testing Fill in the blanks. 1. The linear sequential model of software development is also known as the Classical life cycle model / Waterfall model_. 2. Inception phase is the first phase defined by the Unified Process model for software development. 3. The older software systems that were developed decades ago and have been continually modified to meet changes in business requirements and computing platforms are called Legacy Software / Legacy Systems. 4. Project velocity is the number of customer stories implemented during the first release in XP process.

5. XP process consists of following phases: planning, design, coding, testing. 6. Unified process model consists of following phases: inception, collaboration, construction, transition, (may also be production phase). 7. XP process recommends the construction of a unit test for a story before coding commences. 8. Refactoring is the process of changing a software system in such a way that it does not alter the external behavior of the code yet improves the internal structure. 9. Refactoring is actually performed during coding phase of XP process to improve the internal structure of code. 10. A parallel process flow executes one or more activities in parallel with other activities.
