Estimation uncertainty in software projects is often not driven by the difficulty of the problem we are trying to solve, but rather by the health of our codebase, the quality of process, and how much discipline we have in our management practices. If you want to improve your estimates, then agile and #NoEstimates thinking can have the biggest impact on your team’s success.

Releasing in small batches is a good way to achieve quick feedback in your sprints, but these pieces don't have all the features users need. Providing consumable value is turning those small bites into a meal, and it’s worthwhile to estimate what it will take to deliver that—asking, “What consumable value do we expect to achieve, what duration and cost should we plan for, and how likely is it that the plan will succeed?”

You can use analytical methods to assign business value to a user story, of course, but another way is simple estimation. Allan Kelly describes an estimation exercise that combines the Scrum tool of planning poker with a TV show format to add some fun. You end up with enlightening conversation and revealed requirements.

A good key indicator for measuring how well your agile team is performing is the burndown chart. It’s a simple concept—as time passes, the amount of work to do decreases. Of course, there will be days when progress is not as expected or tasks end up larger than originally estimated. A burndown can help your team reset and keep stakeholders in the loop.
