Total Lines of Code
Handle: LOC
Description: The number of lines in a module. This particular metric includes all blank lines, comment lines, and source lines.
Observation: This metric is generated using McCabeIQ 7.1.
Frequency: Frequency is determined by the requirements of each project.
Scale: This is one line - one count.
Range: No maximum exists.
Usage: This is a standard metric for measuring system size and to an extent effort. This metric has also been shown to be a predictor of error.
Relationship: It is a measure of size.
Threshold: Two hundred is generally accepted. Two IV&V studies show that over 200 lines does significantly increase errors.
Validation: There are two studies that show it as a good predictor of error. Better than 50/50.
