Plan-Driven vs. Vision/Evidence-Driven(Traditional vs. Agile)
Traditional Project Management Agile Project ManagementIssues discovered later in the development lifecycle
Issues discovered earlier in development
Single Integration Periodic / Continual IntegrationStructured by Domain Multidisciplinary TeamsAdds Time / Money to release to adapt to issues / requirements
Reduces functionality in release (pushed to another release) to adapt toissues / requirements
Tracks Progress by Stages Tracks progress by Value (functionality complete)
‘Success’ is measured by conformance to a plan
‘Success’ is measured by delivering useful capabilities (Value)

Measuring Agile Projects
• Similar Challenges– Finding the “right” thing to measure– Ensuring a measure is used for the “right”
purpose– Unintended consequences

Finding the Right Measures
• Practical Software and Systems Measurement
• Goal-Question-Metric Approach• Market Research

Finding the Right Measures(Example)
Defense Innovation Board Metrics for Software Development (July 2018)
Sample Questions1. Does it currently apply to our program?2. Does it inform good decision making?3. Can we get this information from a metric
already being collected?4. What aspect should it be tracked?5. How are other aspects going to track this?6. What is the cost of collection?7. How can we collect it? Can it be automated?8. …

• Agile delivers capability in small chunks allowing us to assess not only the quality of our system, but the quality of our metrics.

What about Funding?
• We pay a FFP per team• Easy to calculate the release cost
– Team 1: 3-Month release = $150• Easy to calculate a feature costs
– Team 1: 3-month release, if a feature is 1/3 of the effort… The feature costs $50.

Team Velocity
• Team Velocity: is a measure of the amount of work a Team can complete during a single Sprint.
• Aspect: Team• Warning:
– Don’t compare one team velocity to another– Don’t use one teams velocity to benchmark a
“new” team
