Planning Poker

At Oliveyoung's Digital Business Division, projects are run based on agile methodology, and Planning Poker was introduced to increase the objectivity of sprint schedule estimation.

Planning Poker aims to derive accurate schedules through reasonable discussion among team members, without being swayed by individual experience or a leader's demands. This session was conducted with 8 members of the frontend part participating.

The process is as follows.

• The User Story and Feature to be worked on within the sprint are shared in advance.
• The minimum unit that can be proposed is limited to 0.5 and the maximum unit to 5, with each person proposing a schedule based on their own experience.
• The members who proposed the lowest and highest schedules explain their reasoning to each other, and a consensus is reached through discussion.

Through Planning Poker, feedback on implementation approaches could be exchanged quickly, and it was of great help in sharing service direction and domain knowledge. However, since approaching things only at the level of a single feature can cause the overall context to be missed, it is practically useful to leave a buffer of 20-30% in the estimated schedule.
