Key driver diagram for reduction in SSEs. A key driver diagram describes the learning structure for a quality improvement project and includes the aim statement, key drivers, and change strategies to be tested or implemented during the project. The aim statement is developed by using SMART (specific, measurable, actionable, relevant, and time-bound) goals and states the primary objective of the project. The key drivers are the elements believed to be crucial to achieving the goal. OR, operating room.
