Use common sense and organizational sensitivity when interpreting metrics data.
Provide regular feedback to the individuals and teams who have worked to collect measures and metrics.
Don't use metrics to appraise individuals.
Work with practitioners and teams to set clear goals and metrics that will be used to achieve them.
Never use metrics to threaten individuals or teams.
Metrics data that indicate a problem area should not be considered “negative." These data are merely an indicator for process improvement.
Don't obsess on a single metric to the exclusion of other important metrics.
