12.14 A hospital has identified nonrandom variations in medication errors. These errors can emanate along a process from prescription orders to delivery to a patient. Hence, consider the departments involved in the process such as nursing, pharmacy and others as appropriate, to:

a. Draw a flow chart for the medication process.

b. Construct a cause - and - effect diagram showing the potential causes of errors.

c. Develop a Pareto diagram to prioritize the causes (problems), for planning to solve them.
