What it means when cycle time runs above or below takt time, how to measure it, and how to compare the two across a multi-station line.

How one-piece flow differs from batch-and-queue production, what must be in place first, its effect on lead time and inventory, and when it does not fit.

Why lead time is almost always longer than cycle time, what Little's Law says about the gap, and how to measure and shrink it.

Takt time is available production time divided by customer demand, the rate at which one unit must be completed to match what customers actually need. Learn how it's calculated and applied.

A FIFO lane connects two processes with a capped, ordered queue that enforces first-in-first-out flow without a kanban signal. Learn when a FIFO lane fits better than a kanban loop or a supermarket.

Production, withdrawal, signal, two-bin and electronic kanban: what each does, how the loop works, and how to work out how many cards you need, with worked examples.

Kanban pull systems use visual signals to trigger replenishment only when it's actually consumed, not a forecast. Learn how the signal, the board, and the governing rules work together to schedule production without a push schedule.

Cp and Cpk are the two numeric measures that answer whether a process is actually capable of consistently meeting specification, not just whether it happened to produce a good part today. Learn how each is calculated, what they mean, and why they aren't the same question.

A practical guide to control charts: the parts of a chart, choosing a type for the data, patterns that signal a shift, and a worked reading example.

Statistical process control uses data to distinguish ordinary process variation from a genuine shift worth investigating. Learn the difference between common-cause and special-cause variation, and why that distinction is the foundation for every other Six Sigma tool.

A standard operating procedure defines the required, approved steps for a regulated or safety-critical activity. Learn how to write, approve, roll out, and maintain an SOP that people actually follow, not just one that satisfies an audit.

A job breakdown sheet does nothing on its own until an operator can perform the job the way it describes. TWI Job Instruction is the four-step method, Prepare, Present, Try Out, Follow Up, that transfers a standard reliably from the sheet to the operator's hands.

Standard work, standard operating procedures, and work instructions are often used interchangeably, but each serves a distinct purpose and audience. Learn what separates them, where they overlap, and which document to use for which job.

Standard work documents the operator's job, but leaves the supervisor's job undefined. Leader standard work closes that gap: a defined, daily routine of checks, gemba verification, and coaching that keeps the operator-level standard from silently drifting.

Standard work is documented using three distinct forms, each serving a different purpose on the floor: the combination table, the standardized work chart, and the job breakdown sheet. Learn what goes on each form, how to actually build one, and how the three work together during training and kaizen.

Takt time, work sequence, and standard in-process stock are calculated, not estimated, and each has a defined formula behind it. Learn exactly how to calculate all three, how they interact when demand changes, and the specific mistakes that produce numbers that look precise but do not hold up in practice.

How lean process management goes beyond standard work: the Purpose-Process-People framework, five conditions a process must meet, and the control toolkit.

Standard work documents the current best-known method for a job across three specific elements, takt time, work sequence, and standard in-process stock, not a rigid rulebook imposed from above.
