AP AP Process Improvement & Optimization 2 — Questions and Answers
Question 1: What is a KPI in the context of process performance monitoring?
- Key Personnel Indicator
- Key Performance Indicator (Correct answer)
- Known Process Issue
- Knowledge and Policy Index
Correct answer: Key Performance Indicator
A Key Performance Indicator (KPI) is a measurable value that demonstrates how effectively a process or organization is achieving its objectives.
Question 2: In process improvement, what does 'cycle time' measure?
- The time it takes to complete one full unit of work from start to finish (Correct answer)
- The number of process cycles completed in a year
- The frequency of equipment maintenance
- The duration of employee training programs
Correct answer: The time it takes to complete one full unit of work from start to finish
Cycle time is the total elapsed time from the start to the completion of a single unit of work, including both active work and waiting time.
Question 3: What is root cause analysis (RCA) designed to accomplish?
- Identify the underlying source of a problem rather than just treating its symptoms (Correct answer)
- Calculate the financial cost of process failures
- Assign blame to the employee responsible for an error
- Create a list of all known process risks
Correct answer: Identify the underlying source of a problem rather than just treating its symptoms
Root cause analysis systematically identifies the fundamental reason a problem occurred so that corrective actions address the source, not just the symptoms.
Question 4: Which chart is commonly used to display process data over time and identify trends or unusual variation?
- Pie chart
- Control chart (run chart) (Correct answer)
- Histogram
- Scatter plot
Correct answer: Control chart (run chart)
A control chart (or run chart) plots process measurements over time with control limits to distinguish normal variation from special-cause variation.
Question 5: What is the purpose of a SIPOC diagram in process improvement?
- To schedule project milestones and deliverables
- To provide a high-level view of a process by identifying Suppliers, Inputs, Process, Outputs, and Customers (Correct answer)
- To calculate the return on investment of an improvement project
- To document the roles and responsibilities of a project team
Correct answer: To provide a high-level view of a process by identifying Suppliers, Inputs, Process, Outputs, and Customers
A SIPOC diagram gives a concise overview of a process, clarifying its boundaries and key elements before detailed mapping begins.
Question 6: In the context of Lean, which of the following is NOT one of the seven classic types of waste (Muda)?
- Overproduction
- Waiting
- Innovation (Correct answer)
- Defects
Correct answer: Innovation
The seven classic Lean wastes (TIMWOOD) are Transportation, Inventory, Motion, Waiting, Overproduction, Overprocessing, and Defects; Innovation is not one of them.
