Lean is a system, method, school of thought, and even a way of life, all focused on reducing waste. Keep reading to get the full rundown on the following lean principles with two techniques for good measure:.

The elimination of waste is core to anything related to lean as a practice. To that end, one of the core lean manufacturing principles to follow is to make sure that there is as little waste as possible in and created by everything that you do. The more waste you eliminate, the more your business saves with every product it produces and every process carried out. 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.

Reducing waste and continuous improvement go hand-in-hand as lean manufacturing principles. By continuing to improve your business and processes you can reduce waste as much as possible by eliminating whatever bottlenecks threaten to pop up and examining which processes are inefficient. Beyond that, continuously striving to improve is a strong approach to take with any repeated task since any improvements you make will benefit all future results.

The only way to continuously improve your practices, however, is to document and manage your processes and procedures first.

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. Heck, you could argue that starting off with bad processes means that you have more to improve and thus more to gain from continuous improvement.

Sure, you might value your employees and want them to be happy and engaged with their work, but making it a core principle running through every element of your business is more than most would be willing to do.

Much of your success with this principle will come down to your communication skills and the dynamics of your team and managers — as much relies on your employees getting on and supporting each other as it does on you doing the same. 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.


In turn, this means that no matter what happens, your output remains the same every day. The theory is solid — by looking at your average order amount you can keep your production consistent and avoid having to rush to meet a particular order.

You can then also calculate how big your safety stock needs to be by looking at the variance in order numbers from your average.

This will no doubt take a little trial and error, but leveling out your production lets you cement the most efficient practices possible and makes your work and output easy to predict. As a manufacturing principle, it focuses on working on a task or jidokw in order to meet demand and nothing more.

Nothing is completed in excess, as that is considered waste think standing inventory. The ultimate goal is to have absolutely no inventory, whether that be raw resources, WIP items, or finished products.

As such, applying JIT to an existing manufacturing operation requires the managers to rethink and nedur the entire thing. If you mess up, be prepared to fail to meet orders. 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.

That way you can benefit from the idea without the same level of danger associated with widespread application. By limiting your WIP to a single item you midoka greatly increase your efficiency and the quality associated with the end result. Think of a production line with several workstations and a bulk order. Using one piece flow, one item is moved into the first workstation, all work there is completed, and then the product is moved to the next station. The next product is meanwhile moved to the first workstation.

One product is always being worked on at any given stage of the process, and nothing is left waiting for a station to be free. Travel times between workstations is as limited as possible usually through an optimized floor layout and tasks are grouped to spread the work as evenly as possible between stations.

The jidoks of having quality built into your manufacturing processes is key to running an efficient, yet successful nedjr. 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.

For example, in a manufacturing process, you might have a task for attaching the arms to a toy robot. A standard process would probably just include instructions for putting the springs on the shoulder joints, then clipping the arms in place. The mistake is then compounded by being nedur if not impossible to spot at a glance, and correcting it later on requires the product to be disassembled.

To save this trouble, the poka-yoke equivalent would just add an extra step to prepare two springs in advance ndir of taking them straight from the stockpile.


At the very least it would let the worker identify their mistake early on and correct it before it becomes a bigger issue. Complimenting poka-yoke is jidoka — the principle that most defects can be automatically detected to completely remove human error from the equation. Rather than jidokz an employee check every product for defects or errors jiroka as a thread breaking on a looma machine is set up jidoks 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. What do you think to using lean in manufacturing? Have any tips or cautionary tales on the topic? Find him on Twitter jidkoa.

Simple, concise, and informative. I have been a Quality Engineer for 7 years and have only picked up on lean mfg principles no official training. My issue is overuse or not proper use of lean mfg principles by my co-workers.
