Agile Metrics
Per the Agile Manifesto “Working software is the primary measure of progress” and in order to measure progress we need metrics.
As an agile coach and practitioner, I respect the relevance of metrics at all levels from teams to programs to portfolios. However please be do not fall victim to the “street light effect” which means we tend to look for data where it can be easily found but does not have much value to the outcome or impact like number of lines of code, team velocity etc. that are most of the time mere numbers that does not help with real outcome .
