Information Radiators
Information Radiators are highly visible displays of project information placed in prominent locations where the team and stakeholders can easily see them, promoting transparency and communication without requiring active effort.
Explanation
Information radiators are based on the principle that information should be passively available rather than actively sought. Common examples include task boards, burndown charts, burnup charts, build status monitors, velocity charts, and cumulative flow diagrams. They are typically placed on walls, large monitors, or other visible locations in the team workspace.
The term was coined by Alistair Cockburn, one of the Agile Manifesto authors. The key characteristic of an information radiator is that it communicates information to passersby without requiring them to ask questions or search for data. This supports the agile value of transparency and reduces the need for status meetings and reports.
For distributed teams, digital information radiators such as project dashboards, shared monitors, and always-on video screens serve the same purpose. The important thing is that the information is current, visible, and easy to understand at a glance.
Key Points
- •Highly visible displays of project information
- •Promote passive information sharing without active effort
- •Examples: task boards, burndown charts, build monitors, velocity charts
- •Support the agile principle of transparency
Exam Tip
Information radiators make project status visible to everyone. If a question asks about improving transparency or communication, information radiators are often the answer.
