We hebben Lean en Six Sigma toegepast in zorg-,  productie-, logistieke en kantooromgevingen.

Succes begint bij een goede implementatie

Men leest wel eens dat  Lean Six Sigma implementaties in de  praktijk niet altijd succesvol zijn.
Soms ontbrak de deskundigheid, een andere keer waren belangrijke voorwaarden voor succes niet aanwezig. Organisaties die écht naar lean excellence weten door te stoten hebben het vermogen om een cultuur- en gedragsverandering bij medewerkers te bewerkstelligen. Het realiseren van een continue verbetercultuur is misschien wel het meest cruciaal voor het welslagen.

Lean (Six) sigma Lexicon

Activity-Based Costing (ABC)
An accounting technique that enables an organization to determine the actual cost of a product or service by tracing the cost back to the specific activities that produce or provide it. Com­pare to Traditional Cost Accounting (TCA).

When opposite sides of a part, tool, ma­terial, or fixture are different in size, shape, or relative position. Asymmetrical differences can be hard to spot, resulting in errors. Compare to symmetry.

(build to schedule) A metric that measures the per­centage of units scheduled for production on a given day that are actually produced on the correct day, in the correct mix, and in the correct sequence.

Core processes
The essential activities an organization must perform to produce products, complete order-fulfillment functions, maintain its assets, and complete all supporting business functions.

Cost shifting
Moving costs from one account to anoth­er without creating any real savings. Cost shifting often hides waste rather than removing it.

Informative inspections
An error-proofing method that provides timely information about a defect so that a root-cause analysis can be performed and process adjustments can be made before significant numbers of defects are created.

Internal processes

Any part or product that is not immediately required for a customer order, such as excess raw materials, work in progress (WIP), and finished goods.

ITO (inventory turnover rate)
A metric that meas­ures how quickly your company sells the products you produce.

Successive inspection
An inspection that is performed after one operation in the production process is com­pleted, by employees who perform the next operation in the process.

Supermarket system
A stocking system in which materials are stored by the operation that produces them until they are retrieved by the operation that needs them. When a store is full, production stops.


When opposite sides of a part, tool, material, or fixture are, or seem to be, identical. The identical sides of a symmetrical object can be confused during an operation, resulting in errors. Compare to asymmetry.

Takt time
The total available work time per day (or shift) divided by customer-demand requirements per day (or shift). Takt time sets the pace of production to match the rate of customer demand.
