Directions:

Participants in an estimation meeting are each given a set of cards. Each card contains an estimate. Units used vary, they can be days, ideal days, story points, etc. The cards are numbered to account for the fact that the longer an estimate is, the more uncertainty it contains (e.g 1, 2, 3, 5, 8, 13, 20, 40). When an item (feature, task, etc.) is presented, without mentioning numbers, a discussion takes place to clarify assumptions and risks.
Each participant then lays a card face down representing their estimate. Simultaneously, the cards are turned over. If all estimates are relatively close, then there is no more discussion needed, the estimate is recorded and the group moves on to the next item. If some participants had high or low estimates, then they are given a chance to justify their estimate as they may have been thinking of something others were not aware of. Repeat the estimation process until a consensus is reached.

Learning Points:

  • The wisdom of crowds is more accurate than individual estimates.
  • Using the cards avoids the influence of others while estimating.
  • It encourages all team members to participate
  • Discourages the talkative members from dominating (too soon anyway).

Правила:

Каждому участнику выдается набор карт. Каждая карточка содержит оценку. Единицы измерения используются самые различные. Это может быть день, идеальный день, Story Point и т.д. Номера на картах расставлены с учетом того, что чем больше оценка, тем больше она содержит неопределенности (например, 1, 2, 3, 5, 8, 13, 20, 40). Обсуждая каждый элемент (часть функциональности, задачу и т. п.), не называют никаких цифр и стараются прояснить предположения и риски.
Каждый участник затем кладет карту со своей оценкой на стол лицом вниз. Все карты переворачивают одновременно. Если все оценки относительно близкие, то больше нет необходимости продолжать обсуждение. Оценка записывается, и группа переходит к следующему пункту. Если некоторые участники дали очень высокие или очень низкие оценки, то они получают возможность объяснить свой выбор, поскольку они, возможно, подумали о чем-то таком, чего другие не знают. Повторяйте, пока оценки всех участников не совпадут.

Выводы:

  • Коллективная оценка является более точной, чем любая индивидуальная.
  • Использование карт позволяет избежать влияния окружающих при оценке.
  • Все члены команды участвуют в оценке.
  • Самые разговорчивые не могут навязать свое мнение остальным (во всяком случае, не сразу).
