RSM produces source code estimation factors which are derived from the actual metrics of the project.  These metrics can be used to generate Estimates to Complete (ETC) for the project or to provide size estimates for other projects.   These estimation factors include size metrics and function metrics.  It is extremely difficult to conceive all the parameters for function point estimation such as the number of function user interfaces and sources of input.  RSM estimation factors derive conceivable numbers for both size and function attribution based upon either LOC, eLOC or lLOC. 

For example:
    Estimated 537 functions
    RSM Factor of 134 eLOC per function  = 71,958 eLOC.
    Using 0.5 labor hours per eLOC  = 35,979 Labor Hours
    Based upon $45 / Labor Hours = $1.6 Million

RSM reports many estimation factors based on the actual work performed and it is up to the end user to determine which factor applies to their project.
