An ideology of lean manufacturing emphasizes maximizing the productivity of the goods and minimizing the waste produced within a manufacturing company.

Any activity that does not add value to the company for which the customer will pay, is considered waste according to the lean principle.
Lean manufacturing often uses the terms total quality management and total productive maintenance interchangeably. There are many similarities between the two programs, but in reality, they are quite different.
TQM vs TPM
The main difference between TQM and TPM is that the goal of total quality management (TQM) is to control quality as much as possible. On the other hand, the goal of total productive maintenance (TPM) is to prevent and predict the quality to improve maintenance affairs.
It may seem like TQM is a bit old-fashioned, considering it was popular in the 80s and eventually replaced by lean manufacturing.
It encompasses the basic elements of lean models that we use today, however, if you take a closer look at the basics of this model.
For manufacturers who find lean strategies difficult to implement, TQM could help lower the learning curve.
In TPM, the goal is to maintain and improve production processes and quality of machines along with the equipment that is used for production, and employees while adding value to products.
High employee satisfaction, high productivity, and high employee morale are some of the major key outcomes of TPM.

What is TQM?
The goal of total quality management (TQM) is to identify, reduce, or eliminate errors in production along with managing the supply chain.
All this is done to improve the customer experience and ensure employees are properly trained.
To achieve total quality management, all parties involved in the production and delivery of the final product or service are accountable for its quality and assures the quality of the end product.
By continuously improving internal practices, an organization can improve the quality of its products and services.
The concept of Total Quality Management refers to a structured approach to the management of organizations as a whole.
The continuous improvement of an organization’s internal affairs is the main objective of the process.
In establishing standards as part of the TQM approach, internal priorities can be taken into account as well as current industry standards.
Despite its origins in manufacturing, TQM can be applied to a wide range of industries. An organization can apply these techniques across all departments as well.
All employees will be working towards the company’s goals, improving the overall performance of the organization. Marketing, production, and training are some of the departments involved in the project.
This approach provides a cohesive vision for systemic change by focusing on long-term change rather than short-term goals.
Therefore, TQM is useful across a variety of industries, including, but not limited to product manufacturing.
What is TPM?
Maintaining the uprightness and the quality of an organization’s working capital systems and the level of quality its products provide is what total productive maintenance (TPM) is all about.
This process emphasizes precautionary and proactive maintenance techniques as well as an employee’s involvement in maintaining the quality of their equipment. It aims to achieve optimal production.
- Zero breakdowns
- Zero stops
- Zero defects
- Zero mishappenings
Taking advantage of total productive maintenance can boost your overall equipment effectiveness for years to come and so on, as it aims to reduce downtime through increased manufacturing of products.
For this to happen, precautionary maintenance should always be at the top of everyone’s agenda.
It is a TPM program that fights this mindset and replaces it with one that focuses on maximizing the availability of the manufacturing machinery and putting it at the center of operations.
The traditional Japanese concept of total productive maintenance was created by Seiichi Nakajima.
During the late 1960s and early 1970s, the TPM process was born from his research about total productive maintenance (TPM).
Main Differences Between TQM and TPM
- TQM is based on quality control whereas TPM is based on improving the maintenance process.
- Using TQM, organizations can systematize management and align departments to improve the quality of their products and reduce defects. Whereas, maintenance personnel is involved in the maintenance of machines as part of TPM efforts to improve efficiency.
- TQM mainly focuses on customer satisfaction whereas TPM mainly focuses on how to satisfy the manufacturer to get high production.
- TQM aims at continuous improvement whereas TPM aims at zero breakdown.
- In TQM, the demand for the presence of employees is voluntary whereas the demand for presence is high in TPM.
Even though, both TQM and TPM have their differences but in some cases, they are very complementary to each other. So many companies are implementing the criterion of TQM and TPM simultaneously to achieve synergies.
If done systematically, both TQM and TPM can result in the production of high-quality products which can satisfy the customer in every aspect.
But one should never forget that even if only TPM is done correctly, the goal of having a TQM processed manufacturing can also be achieved.
But at the end of the day, both TQM and TPM are somewhat related as both of them have one main goal which is to satisfy the customer.
