importance on measurements. To exploit some of the resulting differences, we offer
the following questions and suggested approaches.
Questions you should ask regarding your measurement programs include:
What measures are being collected for each discipline?
Some measures can cover several disciplines, for example effort measures and
earned value. Other measures would be unique to a discipline, such as number
of late deliveries from vendor X or lines of code per hour.
Are there measurement specifications defined for all measures?
A measurement specification should contain a definition of the measure,
source of the data, collection mechanism, criteria for counting, unit(s) of
measure, and expected range value. In addition, guidelines on interpreting
the measurement information including an analysis approach and criteria for
decision making should be documented. Why do we need all this stuff? Well,
measures are like many things in life; ???if it ain??™t written down it ain??™t so.
