2. A function whose inputs are software data and whose output is a single numerical value that can be interpreted as the degree of which the software possesses a given quality attributes. [4] .
The scope of software quality metrics is expanding considerably over the few decades. Metrics as a quality assurance tool has not been applied at an adequate level in the software industry.
