| Question ID 22532 | Change control for business application systems being developed using prototyping could be complicated by the:
|
| Option A | iterative nature of prototyping.
|
| Option B | rapid pace of modifications in requirements and design.
|
| Option C | emphasis on reports and screens.
|
| Option D | lack of integrated tools.
|
| Correct Answer | B |
Explanation Changes in requirements and design happen so quickly that they are seldom documented or approved. Choices A, C and D are characteristics of prototyping, but they do not have an adverse effect on change control.
| Question ID 22533 | An IS auditor finds that a system under development has 12 linked modules and each item of data can carry up to 10 definable attribute fields. The system handles
several million transactions a year. Which of these techniques could an IS auditor use to estimate the size of the development effort?
|
| Option A | Program evaluation review technique (PERT)
|
| Option B | Counting source lines of code (SLOC)
|
| Option C | Function point analysis
|
| Option D | White box testing
|
| Correct Answer | C |
Explanation Function point analysis is an indirect method of measuring the size of an application by considering the number and complexity of its inputs, outputs and files. It is useful for evaluating complex applications. PERT is a project management techniquethat helps with both planning and control. SLOC gives a direct measure of program size, but does not allow for the complexity that may be caused by having multiple, linked modules and a variety of inputs and outputs. White box testing involves a detailed review of the behavior of program code, and is a quality assurance technique suited to simpler applications during the design and build stage of development.
