Analytic techniques that enable accomplishing an activity by quantifying parameters of the task (e.g., inputs, size, effort, and performance). (See also “statistical techniques” and “quantitative management.”)
This term is used in the high maturity process areas where the use of statistical and other quantitative techniques to improve understanding of project, work, and organizational processes is described.
Examples of non-statistical quantitative techniques include trend analysis, run charts, Pareto analysis, bar charts, radar charts, and data averaging.
The reason for using the compound term “statistical and other quantitative techniques” in CMMI is to acknowledge that while statistical techniques are expected, other quantitative techniques can also be used effectively.
