It’s a common practice for teams that are adopting lean development practices to display key information about their processes in team areas where everybody can see it. Visual management boards can create a shared understanding of where the team is in terms of its operational effectiveness. They can also help identify and remove obstacles in the path to higher performance.
How to implement visual management
There are many kinds of visual displays and dashboards that are common in the context of software delivery:
- Card walls, storyboards or Kanban boards, either physical or virtual, with index cards that represent in-progress work items.
- Dashboards or other visual indicators, such as continuous integration systems with monitors or traffic lights to show whether the build is passing or failing. Effective visual displays are created, updated, and perhaps discarded by teams in response to issues that the team is currently interested in addressing.
- Burn-up or burn-down charts (for example, cumulative flow diagrams) showing the cumulative status of all work being done. These allow the team to project how long it will take to complete the current backlog.
- Deployment pipeline monitors showing what the latest deployable build is, and whether stages in the pipeline are failing, such as acceptance tests or performance tests.
- Monitors showing production telemetry, such as the number of
requests being received, latency statistics, cumulative
500errors, and which pages are most popular.
When combined with the use of WIP limits and using feedback from production to make business decisions, visual management displays can contribute to higher levels of delivery performance (PDF).
Common pitfalls with visual management
The most important characteristics of visual management displays are that the team cares about and will act upon the information, and that the display is used during daily work to identify and remove obstacles to higher performance. Common pitfalls when implementing visual management include the following:
- Selecting metrics without the involvement of the team. Visual displays that show metrics that are highly relevant and useful to teams will be used more often. In addition, if teams can have input into the metrics that are displayed on their visual displays by participating in selecting their goals (for example, some teams use OKRs), they will be more motivated to drive progress toward those goals.
- Creating displays that are complex, hard to understand, or do not provide actionable information. It’s easy to create displays using tools that allow high levels of modification or that are fun to play with. But changing layouts and color on a custom dashboard isn’t helpful if the team is working with the wrong metrics or it takes the team several months to implement. Key metrics or rough graphs drawn on a whiteboard and updated daily can be just as effective to keep the team informed.
- Not evolving visual displays. Visual management tools should provide teams with information that addresses issues they are facing right now. It doesn’t help one team to copy the displays of other teams unless the teams work in the same context, with the same challenges and obstacles. As a team’s context evolves, visual displays should change as well. Also note that as teams address obstacles, their visual displays might change to discard old (previously relevant) metrics and highlight new areas of importance.
- Not addressing the underlying problem that the visual display is revealing. Teams sometimes make quick fixes in an effort to make the display “green” again. Displays should be used to drive improvements (fix the problem), not become a goal in themselves (keep the board green). Focusing on managing the metric alone leads to unintended consequences and technical debt. If the display suggests a problem, teams should not just fix the immediate problem. They should also work to identify the underlying issue or constraint and resolve it, even if it’s in another part of the organization. Any inefficiencies will keep showing up, and fixing them earlier will help all teams.
Ways to improve visual management
The goal of visual management tools is to provide fast, easy-to-understand feedback so you can build quality into the product. This feedback helps the team identify defects in the product and understand whether some part of the system is not performing effectively, which helps them address the problem. In order to be effective, such systems must do the following:
- Reflect information that the team cares about and will act on. Having build monitors does no good if teams don’t care whether the display shows an issue (for example, showing that the build status is red, meaning broken), and won’t actually act on this information by swarming to fix the issue.
- Be easy to understand. It should be possible to tell at a glance from across the room whether something needs attention. If there is a problem, teams should know how to perform further diagnosis or fix the problem.
- Give the team information that is relevant to their work. While it’s important to collect as much data as possible about the team’s work, the display should present only data that is relevant to the team’s goals. In the face of information overload, particularly information that cannot be acted upon, people ignore visual management displays; the displays just become noise. The additional data can be accessed and used by the team when they are swarming to fix the problem.
- Be updated as part of daily work. If the team lets the data go stale or become inaccurate, they will ignore the visual displays, and the displays will no longer be a useful beacon when important issues arise. If displays are currently displaying stale or inaccurate data, investigate the cause: is the data not related to the team’s goals? What data would make the display an important and compelling information source for the team?
Teams shouldn’t get caught up in aspects of visual displays that aren’t critical. For example, visual management displays don’t need to be electronic. Physical card walls or kanban boards can be easier to manage and understand, particularly if the team is all in one location. These displays can also help develop valuable team rituals such as physically standing in front of the board to pick up work and move it around. A whiteboard with some key project information that is updated daily by the team is often preferable to an electronic system that’s hard to understand, difficult to update, or doesn’t have necessary information.
Ways to measure visual management
As with all improvement work, start with the measurable system-level goals that the team is working toward. Discover the existing state of the work system. Find a way to display the key information about the existing state, as well as the state you want. Make sure that this information is displayed only to the required precision.
Review the visual displays as part of regular retrospectives. Ask these questions:
- Are the displays giving you the information you need?
- Is the information up to date?
- Are people acting on this information?
- Is the information (and the actions people take in response to it) contributing to measurable improvement towards a goal that the team cares about?
- Does everybody know what the goals are?
- Can you look at your visual management displays and see the key process metrics you care about?
If the answer to any of these questions is no, investigate further:
- Can you change the information or how it’s displayed?
- Can you get rid of the display altogether?
- Can you create a new display? What would a prototype look like? What are the most important pieces of information to include, and how precise do they need to be to help you solve your problems and achieve your goals?
