Performance Improvement & Quality Metrics Flashcards

What does the acronym PDCA stand for in the context of quality improvement cycles?

Answer: Plan, Do, Check, Act

PDCA (Plan, Do, Check, Act) is a four-step iterative management method used for continuous improvement of processes and products.

Which performance metric is calculated by dividing the number of defective units by the total number of units produced, then multiplying by 100?

Answer: Defect rate

The defect rate is calculated as (number of defective units / total units produced) × 100, expressing the percentage of outputs that fail to meet quality standards.

A Key Performance Indicator (KPI) is best described as:

Answer: A measurable value that demonstrates how effectively an organization is achieving key objectives

KPIs are quantifiable measures used to evaluate the success of an organization or a particular activity relative to its stated goals.

Which quality improvement tool uses a diagram shaped like a fish skeleton to identify potential causes of a problem?

Answer: Fishbone (Ishikawa) diagram

The fishbone (Ishikawa) diagram organizes potential causes of a problem into categories, visually resembling a fish skeleton, making it useful for root cause analysis.

What is the primary purpose of a control chart in performance monitoring?

Answer: To monitor process variation over time and detect unusual patterns

Control charts are used to study how a process changes over time, distinguishing between common cause variation and special cause variation.

Which quality management methodology is primarily focused on identifying and eliminating waste (muda) in processes?

Answer: Lean

Lean methodology focuses on creating more value for customers by eliminating waste — activities that consume resources without adding value.

In performance improvement, 'baseline measurement' refers to:

Answer: The data collected at the start of an improvement initiative to serve as a reference point

A baseline measurement captures the current state of performance before any improvement interventions, providing a reference point to measure the impact of changes.
