When you learned how to walk and fell flat on your face the first time did you give up?
(Maybe for a bit).
The same goes for Sprints and any new development process you are implementing – it’s not success out of the box – it’s a slow burn growth and then mass acceleration once it clicks with your team.
If you fail to sprint the first time, start jogging the next (remove tickets), build up a tolerance, figure out what works for your team, and then try again.
But don’t throw it all out because it didn’t work the first time. If we did that, 90% of the code in the world would never have been deployed.
