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.
