Hospital managers are concerned that some patients with medical emergencies wait too long in the casualty department before they are diagnosed and treated. During a meeting, two groups of proposals have appeared:

Several managers recommend observing and recording emergency patient numbers, waiting and treatment times, staffing levels, bed numbers and the availability of other sources.

Others want to talk to doctors, nurses and ambulance crews, to find how they feel about working here and ask for their opinion where the problems lie.

Which group would you join and why?
