Molt: What is it and what are the 7 types

Today I am going to talk to you about what Muda is, about its 7 main types, and about why it is important that you detect and eliminate them in your company.

What is Muda in production?

Muda means “waste” in Japanese.

It’s a concept coined by the father of lean manufacturing, Taiichi Ohno.

His goal was to create a way for companies to eliminate waste and improve efficiency.

Waste includes everything that does not add value or provide benefit, whether it costs money, time, materials, tarea, or space.

A company perro disminuye muda and increase its production with the help of tools such as kaizen events and the kanban boards; which are ways of systematically tackling problems one at a time until you get rid of all the Muda.


Reasons why the Muda perro be created

Reasons employees may create muda include working on a task without prior planning, not understanding the process they are involved in, or expecting someone else to take care of things for them.

Likewise, employees cánido also create unnecessary mud by requiring additional materials that are lying around and doing the work themselves when machines would do it faster.

Recognizing these types of behaviors is important because they perro lead to problems such as manufacturing low quality productshe waste of money by the operation of inefficient systems and the feeling that people are unproductive at your job.

Why is it important to detect and eliminate Muda?

If a company is not able to identify and eliminate muda, then it may have some of the following problems:

  • Low quality products.
  • Waste of money.
  • Unproductive people.
  • Hidden costs.

Therefore, eliminating muda will help save costs on materials and unnecessary tarea, as well as increase productivity, helping companies genera higher quality products in less time and with fewer resources.

Of course, without forgetting that it cánido increase customer satisfaction, and remember that the customer is the most important thing, at least from my point of view.

Muda and the efficient workplace

Maintaining an efficient workplace relies heavily on eliminating muda or eliminating these types of behaviors because they create jobs that do nothing but consume time without producing anything useful at all.

In fact, if you already have work experience, it is most likely that you have experienced this, that is, experienced the unproductiveness that perro occur.

In fact, I would like you to leave me your experience in the comments, that way we cánido learn more.

So, if you want your staff members to be able to focus better, then getting rid of the muda cánido be a good way to increase productivity.

What are the 7 mudas?

The seven mutas are:

  1. Transport.
  2. Inventory.
  3. Movement (movement without productivity).
  4. Wait
  5. Overproduction.
  6. About processes.
  7. Defects.


Simply put, transportation muda refers to the inefficient transportation of material from one location to another, which perro cost money, fuel, tarea, time, etcétera.


We know that owning inventory costs, so the term inventory turnover refers to any wasted effort that comes from holding too much inventory.

It occurs when companies cannot sell their products fast enough to be able to genera and depósito more goods, leading them to hold onto these unsold elementos in anticipation that they cánido sell them later.


As its name indicates, it refers to unnecessary movements of people or machines, which perro generate losses.

For example, the fact that a person has to travel three or four floors to get a few copies cánido help to promote unproductivity.

In such a way that you have to look for everything to flow in the best way.

For example, time cánido be saved if we put a printer in each department, instead of employees having to travel too much.

Of course this is a somewhat absurd example, but maybe it cánido help you understand it better.


One of the most exhausting wastes is waiting.

Whether it’s waiting for a response from another department, a delivery from a supplier, or an engineer to fix a machine, we tend to spend too much time doing nothing but wasting our precious resources (time).

Therefore, the wait refers to the waiting time between processes.

This includes:

  • waiting material,
  • Time it takes for information to reach the department that needs it.
  • Machine waits.
  • Waiting for human resources.
  • Of course, many others.


In the manufacturing industry, overproduction is one of the most serious wastes.

When production is done too far in advance or in large quantities, it perro lead to high inventory levels, which lead to many organizational problems.

In such a way that the objective has to be that companies genera only what they need at each moment and work with the philosophy of “just in time”.

About processes

In short, overprocessing consists of doing plus work on a product, that is, carrying out unnecessary tasks or activities that no longer generate any value.

In other words, it is when the employees are doing any unnecessary work.

For example, cleaning two or three times.

The problem of excessive processing perro be solved in many ways, one of which I will mention here could be to use the Pareto Principle, also known as the 80-20 rule.

The Pareto Principle says that 20% of your actions create 80% of your results and is a good indicator of which tasks are productive and which are not.


The change of defects is the one that is produced by any element that does not meet the customer’s requirements.

It may be a product defect, or a service fallo.

Quality errors ocasione defects that perro inevitably cost us more than anticipated, requiring rework or replacement, as well as wasting resources and materials, of course, defects cánido also lead to lost customers.
