Where do the signals in Radar come from?

Only from data that's already in Peak One: overdue or repeatedly postponed tasks, goals and commitments at risk, the current bottleneck, leaks, profit anomalies, rising customer complaints, experiments without a decision, low inventory and initiatives at risk in the annual plan. Every signal names its source, its evidence and how certain Peak is. If a module has no data, Radar sees nothing there and says so.
