DevOps results - part 1

Last week I was lucky to be copied in to an email to the exec board of my company.

The email was written by the CIO advertising some of the success of our recent deployment automation efforts.

On a very basic level it compares human effort vs. automated effort and therefore cost and time.

The results are pretty amazing (well for us anyway) - we did 39 releases in a week for 1 application saving us 17.5 man days of effort.  We've done 49 this week and it's only Wednesday...

The benefits of this are probably more profound but it's a useful start.

For example...
  • How much time is saved by having environments consistently built? 
  • How much more beneficial is it to have every part of the deployment audited?
These types of things are very difficult to calculate the benefits of.  Thus my point recently at IBM DeveloperConnect (UK) when I said to focus on the softer benefits (like time saved) rather than deep ROI calculations (like money saved).

 Metrics are super important...
  • How do we know if we are delivering value if the team isn't measuring it?
  • How do we know if we are working on the right area's if we aren't measuring it?
  • How do we influence other teams to do more "DevOpsy" things if we can demonstrate the benefit?
