According to the Agile Practice Guide and the PMBOK Guide, an Information Radiator is a highly visible physical or digital display that provides the team and stakeholders with up-to-the-minute data about the project ' s progress without needing to ask questions.
Measuring Progress and Flow: While the Scrum board itself shows the status of individual tasks (To Do, Doing, Done), the metrics used to track the flow of work over time are the Burndown and Burnup charts.
Burndown Chart: Shows the amount of work remaining in the current iteration. It is used by the team to track their progress toward the iteration goal and to see if they are on pace to finish the committed stories.
Burnup Chart: Shows the total work completed compared to the total project scope. This is particularly useful in an " adaptive environment " when merging systems, as it visualizes scope creep (increases in the total work line) alongside the team ' s completion rate.
Transparency: These charts act as the " heartbeat " of the iteration. They allow the team to self-organize and identify if they need to adjust their pace or reduce scope early in the cycle.
Analysis of other options:
Option A: The Product and Sprint backlogs are lists of work to be done, but they are the source of the board ' s data rather than the tracking data used to " check status and manage flow " during the execution phase.
Option B: KPIs and Baselines are terms more commonly associated with Predictive (Waterfall) project management. In Agile, we focus on empirical data like velocity and cycle time rather than fixed baselines.
Option C: Increments are the deliverables themselves (the outcome), and bottlenecks are identified by looking at the board (like a Kanban board ' s WIP limits), but they are not the specific data artifacts typically cited as the primary " radiator " components for status tracking.
Per PMI standards, the use of Burndown and Burnup charts provides the most effective visual representation of work flow and status in an adaptive environment, ensuring that the team can manage their commitments effectively.
