ISO 9126 is meant to be a general model of software quality that can be used by anyone involved with software.

Examine the quality models described in this chapter: Boehm, ISO 9126, and Dromey. For each contributing characteristic of quality, discuss possible ways to measure the characteristic, and describe whether the measure is subjective or objective.
