Read the following scenario and determine whether the problem is sufficiently clear:

The passage of the Affordable Care Act $($ACA$,$ also called Obamacare$)$ in $2010$ required that US hospitals report their performance on new metrics. These new metrics allow the federal government to reimburse hospitals for the costs of care based on their performance quality.

Riverview Healthcare, a large hospital located in the eastern United States, decided to take the challenge of implementing the new performance metrics one step further by also changing the financial compensation plan for its physicians to improve the quality of care. The new plan would compensate physicians with both a base salary and a variable bonus tied to their individual performance on the ACA metrics. According to Riverview's executives, the new plan would give greater emphasis to quality over quantity of care and result in a more patient$-$centered view.

How clearly defined is the problem $($what$,$ who, when, where, why$)?$
