However, what it does mean is that the organisation should only process what the customer wants, in the quantity he wants and when he wants it. Complimenting poka-yoke is jidoka — the principle that most defects can be automatically detected to completely remove human error from the equation.

To learn more about this technique, check out our post on the topic: In turn, this means that no matter what happens, your output remains the same every day.

If you mess up, be prepared to fail to meet orders. To learn more, check out our article on the topic: But your article is very good.

In turn, if you engage your employees and show them the respect they deserve, they will produce a more consistent output which is often also of a higher quality. As with reducing waste, this lets you see where the gaps and inefficiencies in your business are, and thus what can be improved easily or what improvements will have the greatest effect.

At the very least it would let the worker identify their mistake early on and correct jidika before it becomes a bigger issue. However, if you document workflows you follow for everything you do it becomes much easier to see where waste is being generated and how to eliminate it.


Coloured cards representing individual jobs referred to as kanban cards are placed on the heijunka box to provide a visual representation of the upcoming production runs.

Rather than making an employee check every product for defects or errors such as a thread breaking on a looma machine is set up with checks built in to do the task automatically.

When an error is detected, an alarm sounds to let the employees at hand know that something has gone wrong.

The ultimate goal is to have absolutely no inventory, whether that be raw resources, WIP items, or finished products. The word “one” does not necessarily have a literal meaning. This will no doubt take a little trial and nedit, but leveling out your production lets you cement the most efficient practices possible and makes your work and output easy to predict. Japanese business terms Lean manufacturing.

If you can achieve it then great, but otherwise consider breaking your operation into smaller sets of tasks to which JIT can be applied individually. This article needs additional citations for verification. The mistake is then compounded by being hard if not impossible to spot at a glance, and correcting it later on requires the product to be disassembled.

Production control kanban are placed in the pigeon-holes provided by the box in proportion to the number of items to be built of a given product type during a time interval. The idea is that every process can be engineered to inherently prevent mistakes either through re-engineering tasks to suit a standard format or by including specific measures which make sure that mistakes are caught early and corrected.

Views Read Edit View history. This may involve many kaizens to achieve it but it has to be done.

Reducing waste and continuous improvement go hand-in-hand as lean manufacturing principles. In the illustration on the right, the time interval is thirty minutes. Lean is a system, method, school of thought, and even a way of life, all focused on reducing waste.

The heijunka box makes it easy to see what type of jobs are queued for production and for when they are scheduled. One Piece Flow is a fundamental element of becoming lean. Travel times between workstations is as limited as possible usually through an optimized floor layout and tasks are grouped to spread the nddir as evenly as possible between stations. From Wikipedia, the free encyclopedia. It should be related to the customers’ requirements and could be one unit of order.

We have to calculate the takt time for our products or services and ensure that all cycle times are either less than, or equal to, the takt time.
