Estimating Storycards Using PlanningPoker.com
Each week, Menlonians estimate the number of hours it will take to complete storycards for each of our projects. In the office, this was done with a delicate balance of pair conversations and group discussions. The team would discuss the card, then the pairs would put their heads together and discuss between themselves. If a pair had a question or insight, they would get the attention of the whole group to share it.
The problem: We found that when we estimate via a video call, we can’t manage seamless transitions between paired and group discussions (breakout rooms were okay, but did not make for a seamless experience in this case). We hypothesized that this constraint, as well as the addition of new team members (yay!), made it so that all of the developers often estimated the same number of hours for a card. Usually, everyone was choosing the first estimate that was suggested or the estimate suggested by the strongest voice in the room. We wanted to get back to a more robust estimation meeting that included broad dialog, disagreement, and the opportunity for newer team members to meaningfully contribute.
The experiment: As we were discussing this problem, Michael, one of our developers, found Planning Poker! This site is specifically designed for Agile and Scrum teams to estimate remotely. It allows for developers to privately submit their estimate and then the Project Manager can ‘flip’ their estimates to make them visible to all. Then the development team can discuss any surprising discrepancies. This usually looks like a team member with a low estimate asking a team member with a high estimate to explain their choice, or vice versa.
We found that this reinvigorated the estimation meeting and resulted in much deeper discussion of the developers’ conception of the work to be done on cards and how long it would take! Another success for the mantra: “Let’s run the experiment.”
