meetings and implementing action items), cumulatively
199. The time and cost for identifying the defects and correcting them compared
to the estimated cost of not correcting the defects

Questions to Ask When Generating
and re iewing Metrics
Most organizations collect some sort of measurements, even if they are only when
projects start and finish, or how much money has been spent so far. When structuring
your metrics process, you can consider asking the following questions of your
project managers:
What metrics do you collect?
How to they track to the cost??“effort??“schedule metrics needed by senior management
or other corporate activities?
Do you use and understand earned value?
Do you track the time it takes to enter, track, and report metrics?
Do you use any graphs or automated tools?
Which metrics work for you and which ones do not work for you? Why/
why not?

How have you used the metrics?
What problems do you see in entering, collecting, analyzing, and reporting
the metrics?
How do you use the WBS? Does it tie back to the activities tracked by
the metrics?
How are the metrics you collect tied to business goals and the business problems
in this organization?
How do you analyze the metrics data?
How do you verify that the data are correct and accurate?
As for trends, what problems did/does your project have? Do the metrics
reflect this finding? Did using the metrics help you identify this problem?
In which phase of the life cycle did these problems occur?
Do the metrics collected reflect or help you identify the phase of the life cycle
where the problem occurred, or the cause of the problem?
Selection of the metrics to be used on the projects should take into consideration
the size of the project (both in dollars, personnel, and product size); project
classification (Development, Enhancements, or Maintenance); and complexity of
the system being built.
