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

A.
Program evaluation review technique (PERT)

B.
Counting source lines of code (SLOC)

C.
Function point analysis

D.
White box testing

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.
