I’d love to see your experiment with Lego. Feel free to share you story.
Let look at the “RIGHT” team as an example:
First number is a total story point estimate = 409 SP
Second number is the prediction of a time to complete (how many 1-minute sprints, which players should figure out while still not having understand their velocity) = 20 minutes
Third number is actual velocity = 6 SP
4th number is updated total of story points = 331 SP
You might ask how? Logically 409 – 6 = 403. This game is challenging traditional culture when people are not taking care to ideally complete the selected product backlog items. Folks from the “RIGHT” team were very disappointed to know that I didn’t count undone work and accepted only couple of items estimated as 5 and 1. Then I enforced the rule to re-estimate unfinished items. Now, you can easily calculate amount of unfinished work which is 409 – 6 – 331 = 72 SP!!! They learned what quality means for me in this game and what is IDEALLY COLOURED items.
To make long story short, the RIGHT team estimated to complete painting in 20 minutes, they learned that low quality work may result in non-trasparent forecast of 50 minutes, but actually they completed in seven sprints.
If you mind to try it with Lego, think what you consider as low quality, it might be challenging with “ideal” bricks.
Hope that helped.
i would like to use this exercise and change it up with Legos. I just want to make sure I understand the chart you you drew.
The first number is a total story point estimate. the second is the number of 1-minute sprints they estimate to complete it; the third is the actual number of story points they complete( velocity)
The 4th is what i want to clarify – is it a new estimate of story points remaining after they break the work down? Otherwise I would expect it to be the first estimate minus the actual velocity…..
The last number is then expected number of sprints using the new story point estimate divided by the actual velocity.
Great exercise – just want to make sure i do it correctly
