A3 Method A problem-solving format that constrains context, analysis, countermeasures and follow-up to a single page. The size limit is the method: it forces the thinking to be complete and legible rather than sprawling.

Control Charts A chart that separates the normal variation of a stable process from a genuine signal, so teams stop reacting to noise. The basis for deciding whether a shift in an indicator warrants action at all. Control Plan The document that says what gets measured, how often, by whom, and what happens when it drifts — the thing that stops an improvement decaying.

F

1 term

FMEA Failure Mode and Effects Analysis: a structured review of how a process or product could fail, how severe each failure would be, and how likely it is to be detected. Used before problems occur rather than after.

G

1 term

Gage R&R A study of how much of the observed variation comes from the measurement system itself rather than the thing being measured.

H

Heijunka Levelling production so that volume and mix stay steady over time, because variable demand amplifies as it travels upstream.

J

1 term

Jidoka Building the detection of abnormality into the process itself, so it stops on its own rather than producing defects until someone notices.

Lean Manufacturing The production system built on eliminating waste, levelling flow and pulling to customer demand. The origin of most Lean tooling, and the reference point the rest of the discipline extends from. Lean Office Applying Lean to administrative and support processes, where the waste is in handoffs, waiting and rework rather than on a production line. Often where the largest untouched gains sit.

OEE Overall Equipment Effectiveness: availability multiplied by performance multiplied by quality, giving the share of planned time that produced good output at full speed.

Poka Yoke Designing a step so the error cannot be made, or cannot pass undetected — a mechanism rather than a reminder, because attention fails and physical constraints do not. Process Capability (Cp, Cpk) Indices comparing a process's natural spread to the specification it has to meet — Cp measures the spread, Cpk measures the spread and where it sits.

S

1 term

SMED Single-Minute Exchange of Die: cutting changeover time by moving work out of the stoppage, so smaller batches stop being uneconomic.

T

1 term

TPM (Total Productive Maintenance) Total Productive Maintenance: making equipment reliability a shared responsibility between operators and maintenance, rather than a technical function that intervenes only after a breakdown.

V

Value Stream Mapping A map of every step from request to delivery, showing where time is spent and how much of it adds value — usually revealing that most of the lead time is waiting. Voice of the Customer Systematically capturing what the customer actually needs and translating it into measurable requirements, so improvement projects are aimed at value rather than at internal convenience.
