This process is used on sample data from the NASA/GSFC Software Engineering Laboratory and has shown to be a reasonable method to understand ttie underlying process being plotted. Lines of code produced, staff hours, error reports filed, change reports filed, modules created, and modules changed are all reported weekly by project personnel or are extracted automatically from the source code libraries. Once in the data base, we can plot these as raw data weekly scatter plots or as various growth functions to show how the collected statistics change over time.
