Regardless of which size measures (Effective SLOC, function points, objects, modules, etc.) your organization uses to measure software size, code counters provide a fast and easy way to measure developed functionality. If your organization uses Effective (new and modified) SLOC, the output from an automated code counter can generally be used "as is". If you use more abstract size measures (function points or requirements, for example), code counts can be used to calculated gearing factors such as average SLOC/FP or SLOC/requirement.
The QSM Code Counters page has been updated and extended to include both updated version information and additional code counters. Though QSM neither endorses nor recommends the use of any particular code counting tool, we hope the code counter page will be a useful resource that supports both size estimation and the collection of historical data.
