Explain how size-oriented metrics differ from function-oriented metrics. Discuss the pros and cons of each.
What will be an ideal response?
Size-oriented measures are computed by normalizing direct measures of the software engineering process (e.g. effort or defects) over the product size, measured in lines of code. Function-oriented measures are indirect measures that are computed from measures of the information domain of a business application and an assessment of its complexity. Size-oriented metrics are relatively easy to collect, but can present problems when component-based or visual programming methods are applied. Function-oriented metrics can be determined much earlier in the software cycle, but are an abstraction that is open to interpretation.

Try using a stopwatch to time the execution of the programs in this chapter. Time from hitting return on the command until the next prompt appears. What is the relationship between execution time and the length of the sound? Is it a linear relationship (i.e., longer sounds take longer to process and shorter sounds take less time to process)? Or is it something else? Compare the individual programs. Does normalizing a sound take longer than raising (or lowering) the amplitude a constant amount? How much longer? Does it matter whether the sound is longer or shorter?
