What do we mean by software metrics? What are some of the commonly collected software metrics? Why are these metrics important?
Software metrics are used to determine software product properties. Some of the important metrics are :
• Lines of Code (LOC)
• Size of the executable in bytes
• Software structure
• Time taken for testing
• Total number of defects found in the product
• Function points (FP)
• Running time of the program
These metrics help in assessing the performance of the programmers, estimating effort needed for future products, plan for future products, asses th run time performance.
