Measure, measure, measure

If Busch has a mantra, it's measure everything. Before optimization can truly start, you have to know what you're working with through reliable measurements of utilization, downtime and other factors, such as average wait times for patients, or how long it takes to get contrast medium injections or sequences.

And measurements are required both before optimization processes are in place and then again afterward, to make sure interventions are working, Busch says.

"Even if you succeed," he says, "you must have for all these succeeded processes continuous monitoring, otherwise one year later, you're in the old status."
