Health plans conduct evaluations on the efficiency and effectiveness of their quality improvement activities.

effectiveness is the relationship between what the organization puts into an improvement plan and what it gets out of the plan

effectiveness is measured by reviewing outcomes to determine the accuracy or appropriateness of the strategy and the adequacy of resources allocated to that strategy

the effectiveness of an action plan is typically measured with a concurrent evaluation

an evaluation of plan effectiveness produces one of two results: the plan either (a) achieved the desired outcomes or (b) did not achieve the desired outcomes and is unlikely to do so under current conditions
