In Agile projects, it's a common practice to visualize and share project status in “big visible charts” on a wall of the project room. Lean systems also use such devices. "Kanban," in Japanese means, loosely translated, 'card or sign'. In a Lean production system, Kanban is a method which uses standard units or lot sizes with a single card attached to each. A new card is "pulled" into the system only when the work represented by an "in progress" card is completed..

In this paper, I explore visualization methods found widely in agile projects these days, and then propose using Kanban Boards to organize three viewpoints (Time, Task, and Team) so that the whole team understands the current status of the project and can work in an autonomous, motivated and collaborative manner. Finally, I introduce a software tool “TRICHORD” that implements Kanban Boards to realize project visualization from the three viewpoints.

Visualization in Agile Projects

XP has a practice called “informative workspace” where you can see how the project is going on at a glance [Beck05]. A primitive way of doing this is just putting story cards or task cards on the wall. Other graphs and charts on the wall are sometimes called “information radiators” [Cockburn01] or “Visible Big Charts” [Jeffries04] and have become very common in today’s agile project room facilitaties. Below, I show examples of the visualizations found in agile teams in Japan.

The first example in Figure 1 is a Task Kanban Board named after the “Just-In-Time” (JIT) production method used in the TPS (Toyota Production System) [Poppendieck03, 07].

Figure 1: Task Kanban Board

A Kanban means a ticket describing a task to do. In TPS, it is used to realize Just-In-Time “pull” production control. In Figure 1, a Kanban Board shows the current status of all the tasks to be done within this iteration. The tasks are represented by cards (Post-It Notes), and the statuses are presented by areas on the board separated and labeled ToDo, Doing, and Done. This Kanban Board helps the team understand how they are doing well as well as what to do next and makes the team self-directing.

Figure 2 is another type of Kanban Board, called “Feature Kanban Board”. (Highsmith just calls this a “Feature Card Whiteboard Layout”, but I categorize it as a Kanban Board. [Highsmith04]

Figure 2: Feature Kanban Board

The horizontal axis of this chart is a timeline and vertical areas in the timeline represent releases and each card posted to the areas represents one feature that will be implemented in the release. Contrary to the first example which is usually used within the development team, this Feature Kanban provides a high-level overview of the product’s road map so it should be shared with the whole extended team, including customers, marketing staff and management.

Also, the “Parking Lot Chart” in Figure 3 is used to provide a top-level digested summary of project status (not to be confused with a “Parking Lot List,” a tool facilitators use to capture unresolved issues). It is first described in Feature Driven Development (FDD) [Palmer02], and is widely used in agile projects today. It is sometimes also called a “Project Dashboard”.

Figure 3: Parking Lot Chart

Another type of visualization in Figure 4 is called a Burndown Chart.

Figure 4: Burndown Chart

It is first described in Scrum [Schwaber01] to show the remaining backlog, and has now spread to most agile projects [Cockburn04], [Cohn05]. It captures the current status as well as the rate of progress of completing the remaining tasks.

The last interesting visualization in Figure 5 is called Niko-niko Calendar (or Smiley Calendar), a Japanese creation, showing team member’s mood for each day.
Everyone puts a smiley mark onto their own calendar after the day’s work, before leaving the team room [Sakata06]. It looks at the project from the viewpoint of member’s mental health and motivation.

Figure 5: Niko-niko Calendar (or Smiley Calendar)

Kanban Board as Main Information Radiator

To summarize, the visualization tools mentioned are:

  • Kanban Boards. Use a card as a token (Kanban) of a task, story, feature and stick them to a timeline (board). There are several levels of granularities.
  • Burndown Charts. Count the number of Kanbans (backlog tasks) and track it in a timebox to show the trend of work accomplished. There are also several levels of granularities.
  • Parking lot Charts. Summarize the top-level project status.
  • Calendars. Other than Niko-niko calendars, there are a lot of variations of using calendars to show project status or plan.

Note that between Kanban Boards, Burndown Charts, and Parking Lot Charts, Kanban Boards have the most detailed information. Burndown Charts and Parking Lot Charts can be drawn using the information of daily changing Kanban Boards. So hereafter I’ll discuss Kanban Boards as the main information radiators, and Burndown Charts and Parking lot Charts as sub-tool which summarize Kanbans visually.

Organizing Kanbans from Three Viewpoints

Looking closely at Kanban Boards, you can find three things expressed on them – time, task, and team. Here I try to organize Kanbans from these three viewpoints.

Figure 6 Breakdown of Time and Task

1. Time

In agile projects, time of a project is first broken into “Releases” and each release into “Iterations”, and each iteration into “Days”.

  • A release is typically 1- to 6-months long and is the most coarse-grained timebox. It is a sync point of the whole team so everyone in the whole team should be interested in it.
  • An iteration is the second level timebox. It is typically 1- to 4-week long and development teams use it as a major working, tracking and improvement cycle.
  • And every day is the most fine-grained timebox, the team gets together in a stand-up meeting to share project status and problems.

2. Task

There are also three levels of granularity for Tasks. Here I call the top level “Features” and each feature is broken down into “Stories”, and each story into the lowest level “Tasks”.

  • A Feature is a function useful and meaningful to users.
  • A Story is a testable piece of a Feature, also described in the words of users.
  • And a Task is a work unit of a Story, commonly described in terms used by developers.


A project team consists of people working toward the same goal. Typically, a manager, customers, developers, business analysts, users, testers and other stakeholders should be members of the team. The whole team should share information on time and tasks to achieve the project goal.

Kanban Board Maps Task to Time
for the Team

Here I’d like to define a Kanban Board as a mapping between tasks and time for the team. Note that “time” and “task” both have a three-level breakdown structure, and the higher the breakdown levels are, the higher the level of management that should be involved with it. So, it is reasonable to set up Kanbans in combination of Release-Feature, Iteration-Story and Daily-Task as shown in Table 1, although there are many possible other combinations of time and task.

Table 1 Kanban combination of Time and Task

A “Feature Kanban” is good at giving the whole team a high-level view of the project. And it goes with a Parking Lot Chart to show the top level status.

A “Story Kanban” is at the middle level, the most widely and carefully seen in each iteration by the team, and it may be supported by an iteration Burndown Chart.

A “Task Kanban” is at the lowest level, showing the current changing status daily, which may be supported by a daily Burndown Chart.

Figure 7: Overview –
Three viewpoints and Kanban Board as a mapping of Task to Time


We have been developing an agile project management tool named “TRICHORD.” TRI refers to the three viewpoints (Time, Task, and Team) and CHORD means harmony.

It operates as a workplace to share project status across the whole team, providing the three levels of Kanban Boards – Feature Kanban (Release-Feature), Story Kanban (Story-Iteration), and Task Kanban (Daily-Task) – as described in Table 1. A Feature Kanban is supported by a Parking Lot Chart, Story and Task Kanbans are supported by Burndown Charts. 

Figure 8 TRICHORD (Kanban Boards with Burndown Charts, Parking Lots)

In addition, TRICHORD has a Niko-Niko Calendar service to share the team's mood. It also works as a simple “twitter”-like SNS communication center in the projects.

Figure 9 TRICHORD Niko-Niko Calendar

TRICHORD is implemented on the Eclipse RCP (Rich Client Platform), and optionally works with Trac (issue tracking system).

Tracking relative to budgeted/available hours by John Rusk

Burndown (or burn up) charts can easily be suplemented to add tracking against budgeted hours. That way, they track not just the work completed, but also the effort required to complete it. Details here:

Kanban Yahoo Group by HIRANABE Kenji

David Andersen gave me a comment on Parking Lot.

Hi Kenji,

I liked the paper you gave me to read. I wanted to make a comment about the parking lot diagram. It was first introduced on the original FDD project in Singapore and was first documented in Peter Coad's 1999 book, UML Modeling in Color in Chapter 6, the chapter written by Jeff De Luca.


And he started up a new Yahoo Group about Kanban Boards.

Re: Kanban Yahoo Group by Deborah Hartmann

Looks like there's significant interest in Anderson's Kanban yahoo group, his site says "it's acquired members 80 members in only a few days," and he's looking for leads on who else is doing this kind of work.

Excellent article by Bonnie Aumann

I realize I am demonstrating confirmation bias here, but I really like this article's description of the connection between release, iteration and task boards. I look forward to testing out the TRICHORD software - the biggest problem I've had with existing solutions was this lack of hierarchy and association.

Kanban should be real,touchable by yongji zhang

Real kanban carry much information。I prefer its exposure. It is also a furniture for your team.

Re: Kanban should be real,touchable by Alen Balja

Ha ha ha, first time I hear about this Kanban and I just realized I've been doing this all along. To Do, Doing, Done - I had three color stickies Red, Yellow, Green. When green was pasted on the feature, that meant - SHIP! Smileys, another thing, I had thumbs up, thumbs down and neutral to emotionally tag events. Good stuff.

a board based on a sharepoint blog by Bogdan Nedelcu

A blog could be a easy storage for kanban cards, as posts. Categories can be used as areas of Kanban. Add some javascript and a visual representation is also available. Find here some inspiration

Re: Kanban Yahoo Group by David David

Not only Kanban Group but also KanbanTool is gaining popularity extremely fast. For me, it's exactly what I was looking for :)

Parking Lot Charts, WIP and Parking Lot Charts by Stephen Palmer

I can confirm that Jeff De Luca ( adopted and adapted the parking lot chart from another more traditional waterfall project for the first FDD project at United Overseas Bank in Singapore in 1997. I was the development lead on that project (David Anderson was the User Interaction designer). The parking lot chart did first appear in print the Peter Coad and Jeff's book, the correct title of which is Java Modeling in Color with UML and I describe it in greater detail in A Practical Guide to Feature-Driven Development and on my website,

It is interesting to note the hierarchy of feature and user story. FDD has always used a three-level feature-list hierarchy of feature or subject areas containing sets of features for each activity containing features. In FDD features are defined at a level of granularity close to that of a typical user story IME. Features are broken down into tasks during iterations but task progress itself is not reported in any formal way; feature milestones are tracked instead ... but then FDD was designed from the beginning for a larger project and team than the typical Scum/XP 7+/-2 project teams. See also

One important concept for a Kanban board is work-in-progress limits. IMHO, it is this that makes it a true Kanban board. Otherwise, the board is little more, and probably less informative, than the old FDD feature milestone chart.

Great post! by Setawut Phannara

Kenji, it's a pleasure to read your amazing post.
You introduced many tools that I never heard. I believe that many people have done something similar to Kanban Boards; however, Burndown Chart is my new visualization method. It is such a good tool to show your current status and demonstrate the rate of progress through the actual path. I have also done things called "How'd your day go?", it composes of 3 easy questions to get members' feedbacks after the day's work. I think it is similar sort of a smiley calendar. Lastly, I agree with you that graphical methods can encourage collaborative and fun among teams.
