The organization should track and monitor its progress in reaching its spread goals (i.e., outcome measures) and the rate of adoption of the improvements in the target population. Tracking and monitoring the progress of spread involves ongoing data collection, producing regular reports, and providing information to both executive leaders and the adopters in the target population. The outcome measures are often available through automated systems. Data on the rate of spread, however, is often difficult to collect as part of an already existing information system and must be collected and reported by the sites in the target population.

The spread agent compiles both the outcome measures and the data on the rate of spread at least monthly and shares the reports with executive leadership and the adopters. Measurement for spread, as is the case with measurement for improvement in local areas, is used to guide the process rather than for judgment. The spread agent and the executive leaders use the spread measures as a diagnostic tool to identify opportunities to accelerate the adoption of the improvements in the target population.
