Design a software team’s Kanban workflow around the work it actually does: map each item from the point the team commits to it through delivery, then make the states, handoffs, policies, and active-work limits visible. Start with a simple board, agree on how work moves, and adjust it as the team learns. There is no universal set of columns or correct WIP number; the right design makes waiting and bottlenecks clear without turning the board into a chart of job titles.
What makes a Kanban workflow useful for a software team?
A Kanban workflow is a shared description of how work moves through a process. A board makes that flow visible, but the board alone is not the workflow: the team also needs clear start and finish points, defined states, work-in-progress (WIP) control, and policies for moving items through the states.
Scrum.org describes Kanban as “a strategy for optimizing the flow of value through a process that uses a visual, work-in-progress limited pull system.” In practical terms, the team sees what it has committed to, what is being worked on, where work is waiting, and what has been delivered. It uses that visibility to decide what to do next and where to improve.
A useful board helps answer everyday questions without requiring a separate status round-up: What is ready? What is stuck? Is review becoming a queue? Can the team take on another item, or should it finish or unblock work already underway? If columns do not answer questions the team needs to act on, reconsider them.

How do you map the team’s real workflow?
Begin with the team’s existing process rather than a generic template. Kanban University’s change principles include “START WITH WHAT YOU DO NOW” and gaining agreement to pursue change incrementally. This makes the workflow a description the people doing the work can recognize, not a target-state diagram imposed from outside.
- Choose the work item. Decide what a card represents, such as a user story, defect, or service request. Keep the item type meaningful enough that people can understand and move it through the workflow.
- Define the start point. Agree on the event that means the team has committed to the item and its elapsed flow should begin. Do not silently count an item as started merely because it exists in a backlog.
- Define the finish point. Agree on when the customer or recipient can consider the work delivered. “Development complete” may not be the finish if the item still requires review, validation, or deployment.
- Walk through the handoffs. Trace a typical item from commitment to delivery. Note where it is actively worked, where it waits, and what must happen before another person or group can proceed.
- Mark exceptions and blockers. Identify work that can be interrupted, needs special handling, or commonly waits on an external dependency. Make those conditions visible rather than hiding them in a note nobody checks.
- Ask the team to confirm the map. Compare the proposed flow with recent work. If the board cannot show where a real item is, the workflow is missing a state or the item does not fit the agreed model.
Scrum.org’s Definition of Workflow calls for work-item definitions, start and finish points, workflow states, and WIP control. Taken together, these are the essentials behind the columns: a board should show a consistent path, not simply a collection of status labels.
What columns should a software Kanban workflow have?
Use states that reveal meaningful work, handoffs, and waiting. A practical starting example is Backlog → Ready → Development → Review/Test → Validation → Done/Deployed. Treat it as a model to adapt, not a required sequence: the team’s actual commitment and delivery process should determine its states.
| Example state | What it can make visible | Question to settle before using it |
|---|---|---|
| Backlog | Requested work not yet selected for execution | Who can add requests, and how are they prepared for consideration? |
| Ready | Work that meets the team’s criteria for being pulled | What must be understood or agreed before the team starts it? |
| Development | Implementation currently underway | What counts as started, and what limit applies to active work? |
| Review/Test | Work awaiting or undergoing review and testing | Does the board distinguish active review from a queue waiting for review? |
| Validation | Work being checked against acceptance or delivery expectations | Who performs this check, and what result permits the item to move on? |
| Done/Deployed | Work that has reached the agreed finish point | Does “done” mean delivered, or is deployment still a separate step? |
Kanboard documents a comparable example: Backlog, Ready, Work-in-progress, To be validated, Validated, and Deployed in production. The difference between that example and the one above is a reminder that workflow states are choices. Neither list is automatically right for every team.
When should you add a column?
Add a state when it exposes a meaningful step, handoff, or queue that affects decisions. For example, if items routinely wait for review, a visible review queue can help the team see and address that delay. If review is simply part of active development and the team does not need to manage it separately, another column may add ceremony without useful information.

Why not use a column for each job title?
Columns such as “developer,” “tester,” and “product owner” describe people or roles, not necessarily the state of the work. They can obscure whether an item is being worked or is waiting for a handoff. Model the work’s state first; identify responsibility in the card or an explicit policy when that is useful.
How should the team define its policies?
Policies explain how cards enter, move through, and leave each state. Without them, people may use the same column differently, making the board hard to interpret. Keep the rules visible, understandable, and open to revision as the team learns.

For each state, agree on a small set of operational rules. For example, a Ready policy might say that the item has an understood outcome and enough information for the team to begin. A Review/Test policy might specify what evidence or checks are expected before an item can leave review. These are examples, not universal acceptance rules; the team should write criteria that fit its own work.
- Entry criteria: What must be true before an item enters the state?
- Pull criteria: What makes an item eligible to be taken next, and who can take it?
- Quality checks: What review, tests, or validation must be completed?
- Definition of done: What event establishes that the item has reached the agreed finish point?
- Escalation rules: What should happen when an item is blocked or aging unusually long?
- Classes of service: Does some work need a distinct handling policy, and how will the team make that visible?
- Movement authority: Who may move a card, and what evidence or agreement is needed?
Write policies in language the team can apply consistently. If a rule is often misunderstood, revise it rather than relying on people to remember an informal exception. Policy changes should be collaborative: the people doing the work need to understand and agree with how the workflow is meant to operate.
How many tasks should be in progress?
There is no universal WIP limit that fits every software team. Set conservative limits for active stages such as Development, Review/Test, and Validation, then use observed flow to adjust them. A limit is a system-level constraint intended to help the team finish and unblock work, not a personal utilization quota.

When a stage reaches its limit, the default response should be to help move existing work forward rather than start another item. The team can finish an item, help clear a review or validation queue, or investigate a blocker. Microsoft explains that limiting simultaneous items reduces context switching and lead time; Kanban University presents WIP limits as an enabling constraint that supports focus and finishing.
How to set an initial limit without inventing precision
- Identify which stages represent active work or queues the team can influence.
- Agree on a modest starting limit for each relevant stage. The limit should prompt useful collaboration when reached, not make normal work impossible.
- Make the limit visible on the board and explain what the team does when it is full.
- Observe the result: does work finish more predictably, or do items pile up in a different stage?
- Change a limit only when the team can describe the problem it is trying to solve, then inspect the subsequent flow.
The goal is not to keep every person busy with a separate item. Starting more work can increase queues and make completion slower; a full stage is a signal to coordinate around the work already in the system.
How does pull work in a software Kanban system?
In a pull system, stakeholders place requests in a replenishment or backlog queue, and the team takes the next item when downstream capacity is available. Work is not pushed into active stages simply because a request exists or a person appears free.
Agree on what makes an item eligible to be pulled, who participates in replenishing the queue, and how the next item is selected. The team should be able to see both the demand waiting to enter and the work already in progress. If downstream stages are full, the appropriate response is to finish, review, validate, or unblock work before introducing another item.
Pull requires usable Ready work. If the team reaches an open slot but no item meets the agreed criteria, the issue may be in replenishment or preparation rather than development capacity. Make that gap visible and resolve it through the team’s agreed process; do not disguise unprepared work as ready merely to keep a board moving.

Which Kanban metrics should a software team track?
Track measures that help the team understand flow, not numbers that become targets detached from delivery. Scrum.org defines WIP as started but unfinished work, cycle time as elapsed time from start to finish, work-item age as elapsed time for an unfinished item, and throughput as completed items per unit time. Lead time can also be useful when the team wants to understand the wait from request to delivery.
| Metric | What it tells the team | Useful question |
|---|---|---|
| WIP | How much started work remains unfinished | Is the system carrying more active work than it can move forward? |
| Cycle time | How long completed items took from the agreed start to finish | How does the time to complete work vary? |
| Work-item age | How long an unfinished item has been in progress | Which active item may need attention before it becomes a surprise? |
| Throughput | How many items are completed in a unit of time | Is delivery changing over time, and what else changed with it? |
| Lead time | How long work takes from request to delivery, when those points are defined | How long does a stakeholder wait for a requested outcome? |
Use consistent definitions for start, finish, and the work item being counted. If one person starts the clock when a request arrives and another starts it when the team commits, their cycle-time figures do not describe the same interval. Likewise, a throughput count is hard to interpret if the team changes what qualifies as a completed item.
Look at trends and distributions rather than treating one number as a promise or universal target. An average alone can hide unusually old items; work-item age helps focus attention on unfinished work, while cycle-time history describes work that has completed. Throughput supplies context about completed volume, but it does not explain quality or value by itself.
A cumulative-flow view can help show how work accumulates across states over time, if the team’s board or reporting setup supports it. Read any widening queue as a prompt to investigate the underlying handoff or capacity constraint, not as proof of a single cause. The metric points to a question; discussion and observation help explain it.

- Daily flow check: Review blocked items, unusually aging work, and full stages. Decide whether to help finish or unblock something before pulling another item.
- Stakeholder delivery review: Discuss what was delivered and whether it met the need. Use the conversation to improve how requests are selected and prepared.
- Service-delivery or improvement review: Inspect the workflow and its measures, identify a change worth testing, and decide how the team will judge its effect.
Kanban University recommends collaborative, experimental improvement. Treat a changed WIP limit or policy as a hypothesis: make one deliberate change, observe what happens to flow, then keep, adjust, or roll it back. Changing several rules at once makes it harder to understand which change affected the result.
What common Kanban workflow mistakes should you avoid?
- Copying a template without mapping current work: The board may look familiar but fail to show the team’s real handoffs, waiting, or finish point.
- Adding too many narrow columns: A state that does not change a decision can make the board harder to maintain without revealing a useful queue.
- Treating WIP as an individual score: Limits govern the system’s load. They are not a measure of how busy each person should look.
- Starting work whenever a card is available: Pull depends on capacity and agreed readiness, including downstream capacity—not just an empty development slot.
- Hiding blocked work in a normal state: A blocked item can appear active while making no progress. Surface the blocker and agree on an escalation response.
- Tracking metrics without stable definitions: Changing the start or finish point makes comparisons unreliable.
- Imposing workflow rules on the team: Arbitrary columns or limits are less likely to reflect the work. The team that does the work should own its Definition of Workflow.
- Changing the whole system at once: Make a focused change and inspect its effect so the team can learn from the outcome.
How should a team start and improve its Kanban workflow?
A practical first version does not need a perfect tool or an elaborate process manual. It needs an agreed work item, boundaries for start and finish, states that show meaningful flow, visible policies, and a way to control active work. The team can improve the design as it sees real items move through it.
- Draw the path an item follows today, including waits and handoffs.
- Choose clear states that expose the steps the team needs to manage.
- Agree on what makes work ready, how it moves, and what counts as delivered.
- Set initial WIP limits for active stages and agree to swarm on finishing or unblocking when a limit is reached.
- Use a pull decision to bring in work only when the system has capacity.
- Track WIP, cycle time, work-item age, and throughput with stable definitions.
- Review the flow, select one improvement experiment, and keep, adjust, or reverse it based on what happens.
The durable design is not the board with the most columns or the strictest limits. It is the workflow the team can use to see demand, finish work, spot delays, and adapt together. As Kanban University puts it: “Stop starting, start finishing!”

Should production incidents go on the same Kanban board as planned software work?
The workflow should make interrupt-driven work visible rather than letting it silently displace planned items. If incidents need different handling, define a class-of-service policy and make its effect on the team’s active work explicit.
Can a Kanban board show work that is blocked by another team?
Yes. Keep the item visible in the state that reflects its actual progress and mark the dependency or blocker so it can be reviewed. Moving it to Done or removing it from view would make the board less useful for understanding unfinished work.
How often should a team change its Kanban workflow?
Change it when the team has a specific problem to address and a way to observe the result, rather than on a fixed schedule for its own sake. Small, agreed experiments make it easier to tell whether a policy change helped.
Does a Kanban workflow require a particular software tool?
No particular tool is established as necessary for the method. The essential requirement is a visible, shared workflow with policies and WIP control; a digital board is useful when it supports the team’s collaboration and reporting needs.
