Velocity to agile is like Flow Efficiency To devops… Flow Efficiency @jbaruch #DataDrivenDevOps #PureAccelerate http://jfrog.com/shownotes

Slide 22

Very much alike! Metric Flow Efficiency Velocity @jbaruch Easily understandable Unity actionable ✓ ✓ ✗ ✓ ✓ ✗ #DataDrivenDevOps #PureAccelerate http://jfrog.com/shownotes

Slide 23

Slide 23

Poll time! Who knows what velocity is? Who knows what burndown chart is? Who has a burndown chart? Who looks at the burndown chart? Who trusts the burndown chart? Who knows what to do if it doesn’t look right?
