Count, don't estimate.
#NoEstimates, championed by Woody Zuill and Vasco Duarte, asks whether the effort of estimating pays off. Often, counting items works as well.
The idea
Small And Similar
Split work into small items of similar size. Count items instead of sizing them.
What you need
The Basics
Reasonably stable flow, consistently small stories, and throughput history.
What it isn't
Not “No Dates”
It's not refusing to forecast. People still need to know when.

Count the work. Keep it small. Still forecast.
