敏捷估算技术
了解在敏捷团队中估算工作的最有效方法。
In agile development, estimation is more than just assigning numbers — it is about building shared understanding across the team. A good estimate is a conversation starter, not a commitment set in stone. Agile estimation techniques give teams a structured way to discuss the effort and complexity of work, surface hidden risks, and align on priorities before a single line of code is written.
计划扑克
Planning Poker brings every perspective in the room into the estimation process. Each team member independently selects a card representing their effort estimate, then all cards are revealed simultaneously. This prevents anchoring — the tendency for early opinions to pull everyone else's estimate along — and instead surfaces the full range of thinking on the team.
When estimates differ significantly, the team discusses the reasons. This is where Planning Poker earns its value: the conversation reveals assumptions, uncovers hidden complexity, and builds a shared mental model of the work. Rounds continue until the team reaches consensus.
The result is an estimate everyone understands and owns — not a number handed down from above, but one the whole team arrived at together.
斐波那契数列
The Fibonacci sequence — 1, 2, 3, 5, 8, 13, 21, 34… — is the most widely used scale in Planning Poker for a good reason: it mirrors the way complexity actually works. Small tasks are relatively easy to distinguish from each other, but the difference between a large task and a very large task is much harder to pin down precisely.
The growing gaps between Fibonacci numbers reflect this reality. Forcing a team to choose between 13 and 21 rather than 14 or 15 acknowledges the inherent uncertainty in larger estimates and prevents the illusion of false precision.
PlanPoker supports Fibonacci out of the box alongside other popular decks. Teams can also build fully custom decks to match their own language and workflow.
T 恤尺寸法
T-shirt sizing replaces numbers with familiar labels — XS, S, M, L, XL, XXL — making estimation more approachable for teams that aren't yet comfortable with story points, or for high-level backlog grooming where relative size matters more than precise effort.
Without numbers in the room, conversations tend to stay focused on relative complexity rather than drifting into debates about exact hour counts. This makes T-shirt sizing particularly useful in early planning sessions, roadmap discussions, or cross-team estimation with non-technical stakeholders.
PlanPoker includes a T-shirt sizing deck ready to use, with no setup required.
