What Is Online Planning Poker?
Online planning poker is a browser-based implementation of the consensus-based agile estimation technique invented by James Grenning in 2002 and popularised by Mike Cohn. In a classic planning poker session, everyone around the table simultaneously reveals a physical card representing their estimate for a user story. Online planning poker replicates this mechanic for distributed teams — all votes are cast privately, then revealed at the same moment.
The key property that makes planning poker effective is simultaneous reveal. Because no one sees anyone else's estimate before committing, the group avoids anchoring bias — the tendency to converge on the first number heard rather than thinking independently. Online tools that show votes as they come in break this property and produce worse estimates.
How Online Planning Poker Works in EstiVote
Running a planning poker session takes three steps:
- Create a room — choose your card deck (Fibonacci is the default), name the room, and you get a shareable link. No account is required for the host.
- Invite the team — paste the link in Slack, Teams, or your sprint planning call. Teammates join by entering a name — nothing else. No logins, no installs.
- Vote, reveal, discuss — the facilitator names a story, everyone picks a card in private, then all cards flip at once. If estimates converge, move on. If they spread wide, the team discusses the gap and re-votes.
Optional features like a countdown timer, spectator mode for observers, and session history are available with a single toggle. You can run five rounds or fifty in the same session without any setup between them.
Why Teams Switch From Spreadsheets to Online Planning Poker
The most common alternative to a dedicated planning poker tool is a shared spreadsheet where team members type their estimates. Spreadsheets have two critical problems:
- No simultaneous reveal. Votes trickle in and early entries anchor everyone else's thinking.
- No discussion structure. There is no natural way to surface outliers, flag uncertainty with a '?' card, or track which stories were debated before reaching consensus.
A purpose-built online planning poker tool enforces the hidden-vote-then-reveal mechanic that makes the technique statistically sound. It also gives the facilitator controls (reveal, reset, next story) without requiring everyone to edit the same document simultaneously.
Key Features for Effective Online Estimation
Not all online planning poker tools are equal. The features that matter most in practice:
- Simultaneous reveal — votes must be hidden until everyone has voted or the facilitator triggers reveal.
- Spectator mode — product owners and observers can watch without skewing the vote.
- Round timer — an optional countdown keeps estimation crisp and nudges the team to commit rather than deliberate indefinitely.
- Session history — a log of every story, its average, and whether consensus was reached, available to review at any time.
- Custom decks — the ability to switch between Fibonacci, T-shirt sizes, hours, or a deck you define yourself.
Who Uses Online Planning Poker?
Online planning poker is used by any agile team that estimates before committing to a sprint. The most common users are scrum teams running sprint planning ceremonies, product teams doing backlog refinement, and agile coaches facilitating estimation workshops across multiple squads.
Remote and hybrid teams benefit most: rather than juggling physical cards on a video call, the entire ceremony runs inside a browser tab that every participant has open alongside their video conferencing tool.
