Lessons leant from Mike Cohn: 2 Times to Play Planning Poker and 1 Time Not To

I read this: 2 Times to Play Planning Poker and 1 Time Not To this morning.

The last part in particular is interesting and has taught me something; I’ve sometimes encouraged teams to validate estimates in sprint planning, but Mike’s point seems solid as to why this is a bit pointless; these estimates are supposed to be rough.

I don’t however get teams to estimate tasks or do any time based estimation; which Mike seems to assume you would do in planning. I get the trends I need from points and I haven’t found time based estimates add anything extra.

I’ll happily give up estimating at all in sprint planning though and just estimate in refinement!
