Kanban board
Definition
A Kanban board is a visual project management tool that represents a team's workflow as a series of columns — each column a stage in the process — where work items (cards) move from left to right as they progress from backlog to done.
The Kanban board is the central artifact of the Kanban method. It makes invisible work visible — at a glance, anyone can see what's being worked on, where things are stuck, and how much is in flight.
Basic column structure:
- Backlog / To Do — work waiting to be started
- In Progress — actively being worked on
- Review / QA — awaiting feedback or testing
- Done — complete
More mature teams add sub-columns (e.g., "In Progress" splits into "Dev" and "Code Review"), swimlanes for different work types, and blocking lanes for stuck items.
Physical vs. digital: Physical Kanban boards (whiteboard + sticky notes) are popular for co-located teams because of their tangibility and the social ritual of physically moving a card. Digital boards (Jira, Trello, Linear, Asana) scale better across remote teams and provide metrics.
Many teams run physical boards for the texture of in-person collaboration and sync to a digital tool periodically. BoardSnap AI bridges this gap — snap the physical board and get a structured snapshot of every card and its column, shareable with the remote team instantly.
WIP limits on the board: A Kanban board without WIP limits is just a visual to-do list. WIP limits (e.g., "maximum 3 cards in In Progress") are what make the board a flow optimization tool. When a column hits its limit, the team stops pulling new work and focuses on finishing what's in flight.
Metrics the board enables: Cycle time (how long a card takes from start to done), lead time (how long from request to delivery), throughput (cards completed per week).
Examples
- Six-column physical Kanban board: Backlog / Ready / Dev / Code Review / QA / Done — WIP limit of 2 on Dev and Code Review
- Trello board used as a Kanban board for a two-person startup, with cards for each feature and bug
- Support team's Kanban board has a 'Blocked' swimlane to surface tickets waiting on external parties
- Physical board photographed with BoardSnap after a mid-week board refresh to share state with remote team members
- Design team's Kanban board: Ideation / Wireframing / Prototype / Stakeholder Review / Delivered
