CEN 5035 Comprehensive Review Worksheet Note: On all written work submitted for credit in this course, it is assumed that by that act of submission you pledge to have neither given nor received unau... thorized aid on the work submitted. 1. (5 pts.) Sommerville notes that a particularly difficult situation for professional engineers arises when their employer acts in an unethical way. One example he gives concerns a company that is responsible for developing a safety critical system and, because of time pressure, falsifies safety validation records. What does Sommerville advise that a software engineer employed by such a company do in this situation? (Circle ONE only.) a. Since the example concerns a safety critical system with predefined validation criteria, Sommerville feels that the blatant falsification of records must always be reported to both development and customer management, and if necessary, made public. b. Sommerville argues that since the predefined validation criteria being falsified may be unnecessarily strict, the software engineer should always defer to management judgment in such situations. c. Sommerville notes that because the system may fail and cause an accident even when properly validated, it is not the responsibility of the software engineer to alert anyone of the situation. d. Since the engineer is an employee of the development organization, his responsibility is to always maintain confidentiality and resolve the situation in such a way that does not embarrass his employer. e. Sommerville argues that the software engineer must make up his own mind in such matters. The potential for damage, the extent of the damage, and the people affected by the damage should influence the decision. But one should always try to resolve the situation while respecting the employer’s rights. f. He advises employers and employees to make their views concerning such issues known to each other in advance (of offering or accepting a position in the organization). g. (None of the above.) 2. (5 pts.) One of the issues of professional and ethical responsibility for software engineers discussed in class was that of "competence." Which ONE of the following, if any, describes the issue as discussed? a. To maintain independence and sound judgement concerning ethical issues that may arise in a project, software engineers should ideally have an ample competence and minimal obligations. b. Software engineers suspected of unethical behaviour must first be found competent to defend their actions before being required to take part in any formal disciplinary review process. c. Software engineers should be aware of local laws governing the legal authority (i.e., competence) of courts or other bodies to deal with the intellectual property issues that may arise in software development. d. Software engineers should never knowingly accept work which is outside their company. e. Licensed, professional software engineers are expected to demonstrate competency in all aspects of software development and for all application types. f. Software engineers should never misrepresent their current level of compensation. g. (None of the above.) 3. (10 pts.) Consider the following statements related to the CMMI process improvement framework. Circle either "true" or "false" as (most) appropriate. a. CMMI assessments involve directly examining true false the processes employed during a randomly selected on-going project and rating these on a six-point scale. b. The CMMI identifies desirable organizational true false states (goals) that are associated with each of 22 process areas relevant to software process capability and improvement. c. CMMI generic goals and practices are NOT true false technical but are associated with the institutionalization of good practice. d. The result of a staged CMMI model assess- true false ment is a capability profile showing each process stage and its associated process capability assessment. e. The continuous CMMI model allows an organization’s true false process capability to be assessed and assigned a maturity level from 1 to 5. 4. (20 pts.) Match each description/image below to the SINGLE MOST APPROPRIATE TERM among the following. (Note: terms may apply to none, one, or more than one description.) A. Incremental DEVELOPMENT F. Cleanroom SE B. Boehm’s Spiral Development G. RUP C. Integration and configuration H. Waterfall D. Incremental DELIVERY I. IDE E. Throw-away Prototyping K. COCOMO II _C__ Some control over system evolution is lost as new versions of some components are not under the control of the organization using them. _G__ Development phases are inception, elaboration, construction, and transition. _B__ Each phase of development involves objective setting, risk assessment and reduction, development and validation, and planning. _I__ A framework within which tools are combined to work together in support of software engineering process activities. _E__ Can lead to the “Pressurizing the Developer” problem discussed in the text/notes. _D__ A problem with this approach is that even though the software is used in real, operational processes, it can be difficult to identify the common facilities that will be needed by different parts of the system in advance. _F__ There is no unit testing for defects in the process and the system testing is focused on assessing reliability. _A__ From a management perspective, a problem is that the process is not visible. Managers need regular deliverables to measure progress. _H__ In practice, the process is not a simple linear model but involves feedback from one phase to another. Documents produced in each phase may then have to be modified to reflect the changes made. _D__ Usually results in faster delivery of software, but inevitable requirements compromises may lead to a system that do [Show More]
