A Pareto chart is a specialized type of bar chart that displays categories in descending order of frequency or cost (time or money), and a line chart representing the cumulative amount12. The chart effectively communicates the categories that contribute the most to the total1.

Pareto charts are primarily used to help teams identify the most significant data in a data set, allowing teams to focus on the data that will enable them to have the most substantial impact3. In other words, these graphs identify the 20% of categories that are responsible for 80% of the outcomes1.

Pareto charts are powerful tools for guiding decision-making and problem-solving endeavors in an organization1. They are useful for identifying the most frequent outcome of a categorical variable4.

Therefore, a Pareto chart can be used to establish priorities for improvement (Option C), rather than graphically displaying a process (Option A), displaying variation (Option B), or establishing a relationship among variables (Option D).

 A SIPOC diagram is a tool used in the Six Sigma methodology. SIPOC stands for Suppliers, Inputs, Process, Outputs, and Customers. During the Define phase of DMAIC, a SIPOC diagram is often used to identify relevant elements of a process improvement project. It helps to understand the process, identify the resources needed, and establish a clear starting and ending point for the process. It’s particularly useful in the planning stage of a project to define the scope12.

Motion-sensor faucets represent a human factors engineering solution in infection prevention. Human factors engineering focuses on designing systems and devices that reduce the potential for human error and improve efficiency. Motion-sensor faucets minimize the need for physical contact, reducing the potential for cross-contamination and helping to prevent the spread of infections in healthcare settings.

Antibacterial soap (A): While important for infection prevention, it is not a human factors engineering solution but rather a hygiene product.

Antimicrobial stewardship (C): This is a programmatic approach to using antimicrobials responsibly, not an engineering solution.

Instrument sterilization (D): This is a standard infection control process but not specifically a human factors engineering approach.
