A balancing measure is a metric used alongside a primary improvement measure to detect unintended consequences elsewhere in a process, such as additional courier workload created by faster instrument delivery.
In a DMAIC project on surgical instrument availability, the primary measure might track whether instruments reach the operating room by the agreed time. A balancing measure could track staff minutes spent clarifying and managing each request. A revised request format may improve availability while increasing administrative work for operating-room staff. Measuring both outcomes gives the project team evidence for deciding whether to adopt or revise the change.
The measurement plan specifies whose workload is counted, which activities qualify, and how observations are sampled. Baseline and pilot measurements need comparable definitions and collection methods. Before pilot testing, the team agrees what increase in request-management time would trigger a review. That decision should reflect clinical requirements and staffing constraints.
Balancing measures complement FMEA by checking whether anticipated side effects occur during a test. They also expose consequences the risk review missed. Within DMAIC, they belong in Measure planning and Improve evaluation. A control plan can retain a balancing measure when the risk persists after implementation, with a named owner and a response threshold for added workload.
