All 27 terms
- Six Sigma
- A data-driven methodology for reducing defects and variation in a process to improve quality.
- Lean
- An approach focused on maximising value and eliminating waste in a process.
- DMAIC
- The core improvement method: Define, Measure, Analyze, Improve, Control.
- Define
- The first DMAIC phase: framing the problem, scope, customer needs and project charter.
- Measure
- The DMAIC phase that maps the process and quantifies current performance with data.
- Analyze
- The DMAIC phase that identifies root causes using statistical tools.
- Improve
- The DMAIC phase that develops, pilots and implements solutions to the root causes.
- Control
- The DMAIC phase that sustains improvements with control plans and monitoring.
- Project charter
- A document that defines a project's problem, scope, goals, team and timeline.
- Voice of the Customer (VoC)
- The expressed needs and expectations of the customer that drive requirements.
- Critical to Quality (CTQ)
- The specific, measurable customer requirements a process or product must meet.
- SIPOC
- A high-level process map of Suppliers, Inputs, Process, Outputs and Customers.
- Process map
- A diagram of the steps in a process, used to understand and improve flow.
- Defect
- Any output that fails to meet a customer requirement (a CTQ).
- DPMO
- Defects Per Million Opportunities: a standardised measure of defect rate.
- Process capability (Cp, Cpk)
- Indices that compare how well a process meets its specification limits.
- Measurement System Analysis (MSA)
- A check that the way data is measured is accurate and consistent.
- Variation
- The natural or special-cause spread in process outputs that Six Sigma works to reduce.
- Hypothesis test
- A statistical test used to decide whether a difference or effect is real or due to chance.
- Correlation
- A measure of how strongly two variables move together.
- Regression
- A statistical method that models the relationship between variables.
- Fishbone diagram
- A cause-and-effect (Ishikawa) diagram for brainstorming root causes.
- Pareto chart
- A bar chart ordering causes by frequency to find the vital few.
- FMEA
- Failure Mode and Effects Analysis: a method to anticipate and prioritise risks.
- Poka-yoke
- Mistake-proofing: designing a process so errors are hard or impossible to make.
- Statistical Process Control (SPC)
- Using control charts to monitor a process and detect unusual variation over time.
- Kaizen
- A philosophy and practice of continuous, incremental improvement.
