Playing planning poker<br />

To come up with accurate estimates, you need to get rid <strong>of</strong> all those assumptions that put<br />

your estimates at risk <strong>of</strong> being wrong. You want a set <strong>of</strong> estimates that everyone believes in<br />

and are confident that they can deliver, or at the very least you want a set <strong>of</strong> estimates that let<br />

you know what assumptions everyone is making before you sign on the dotted line. It’s time<br />

to grab everyone that’s going to be involved in estimating your user stories, sit them around a<br />

table, and get ready to play “planning poker.”<br />

Place a user story in the middle <strong>of</strong> the table<br />

This focuses everyone on a specific user story so they can get their heads around<br />

what their estimates and assumptions might be.<br />

Everyone is given a deck <strong>of</strong> 13 cards. Each card has an<br />

estimate written on one side.<br />

You only need a small deck, just enough to give people several options:<br />

Hmmm...any thoughts on what it<br />

means if someone plays one <strong>of</strong> these<br />

cards for their estimate?<br />

We want a solid estimate for<br />

how long it will take to develop<br />

this story. Don’t forget that<br />

development should include<br />

designing, coding, testing, and<br />

delivering the user story.<br />

Don’t have enough<br />

info to estimate? You<br />

might consider using<br />

this card.<br />

All <strong>of</strong> these<br />

estimates are<br />

developer-days (for<br />

instance, two mandays<br />

split between<br />

two workers is still<br />

two days).<br />

If any player uses<br />

this card, you need<br />

to take a break from<br />

estimating for a bit.
