      Perhaps it was the initial guessology (sometimes called estimating) that FAILed! Perhaps that person who became ill didn't see it coming. You have actually stated two apparent areas of 'FAILURE'. The first is the pre-sprint activity, of estimating, planning, preparation. The second is the actual sprint period and activity. Putting it another way, if I say it will take 1 week to do something, and it in fact takes 2 weeks, then there are two very distinct possible areas where things 'FAILED'. My estimate may have been 50% shy of the mark, or I just didn't perform very well during the sprint, thereby confounding the estimate.
      Rather than talk about FAILed, put it another way ... OPPORTUNITY. You now have an opportunity to review, consider, learn ... whatever you want to call it ... about what to do differently, and presumably better, in the future. If you do not take on this opportunity, THEN you will have FAILed. If you learn nothing from your experience and from the problems that you have obviously already identified, THEN you will have FAILed. So far, you haven't FAILed, you have merely discovered some of the ways of not doing things.

      Failed seems like a strong word, especially when written in capital letters.


      1. In the first sprint it's normal for a team to accept work on a "commitment" basis because they don't yet have a historical velocity to use as a guideline. Management should not see this as a "target." It's just a reasonable guess to get things started.

      2. It's normal for developers to be optimistic initially about how much work they can complete.

      3. It usually takes 3-4 sprints for the team to get used to working together and to ramp up to their normal velocity. What happens before that isn't "failure," it's just normal ramping-up stuff.
