Answer:
The answer is A. Pareto Charts
Explanation:
The Pareto Chart is mostly used in investigating multiple problems and pointing out which of them should be prioritized from most important to the least. This was the brainchild of Vilfredo Pareto from the 1990's, an Italian economist who based this chart on the principle that's are naturally unequal in distribution, or the "law of significant few versus the trivial many."
Also, the Pareto principle or 80/20 rule briefly states that 80% of the effects from the listed problems come from 20% of those that caused it.
Why use the Pareto Chart?
- Evaluate the collected data about the incidence of problems or prevalence of issues within a procedure.
- Determine the problem you want to focus on despite the long list of problems.
- Analyze the whole system and focusing on specifics of a certain procedure/program, if it needs modifications or monitoring.
For example, the attached file has compiled a list of problems regarding medication errors that needs to be addressed, with the most prevalent (arranged from most to least):
- Dose missed
- Wrong time
- Wrong drug
- Over dose
To briefly analyze this, most of the above effects (the 80%) are caused by the ones who give the medications (the 20%). By improving the 20%, we may be able to lessen the 80% of the problems listed. This saves time as the problems are identified and prioritized immediately.
