If you’re working in the manufacturing industry, you’ve probably heard the term ‘Total Productive Maintenance‘ thrown around a lot. But what exactly is it, and how can it benefit your manufacturing process?
Optimizing production efficiency and reducing downtime is crucial in today’s fast-paced and competitive market. It is where TPM comes in – by implementing this approach, manufacturers improve equipment reliability, increase employee engagement, minimize waste, enhance product quality, and boost profitability.
Whether you’re new to the field or looking for ways to streamline operations, let’s dive deeper into understanding productive maintenance with our beginner’s guide!
What is Total Productive Maintenance (TPM)?
TPM is a preventative maintenance program that aims to maintain equipment and reduce downtime. It includes scheduled and unscheduled maintenance, as well as operator-led activities. And can be used in any industry but is particularly effective in manufacturing, where downtime can be costly.
Nakajima first developed a TPM solution in the 1970s to improve equipment reliability in Japanese manufacturing plants. Companies around the world have since adopted it. And is often seen as a part of Lean Manufacturing, as both philosophies focus on continuous improvement and reducing waste. It aims to keep equipment running at peak efficiency while reducing the need for repairs and accomplished through regular maintenance, both scheduled and unscheduled.
Total Productive Maintenance emphasizes operator involvement in equipment care, as operators usually notice when something isn’t working correctly. Operator-led activities include cleaning and lubricating the equipment, checking for wear or damage, and reporting any problems to maintenance staff. These activities help keep the equipment running smoothly and prevent minor issues from becoming big.
Trained technicians typically perform scheduled maintenance, including inspections, calibrations, and replacement of worn parts. Where else, when a problem is detected and involves more extensive repairs, unscheduled maintenance is performed. TPM can be adapted to any manufacturing system, effectively reducing downtime, equipment reliability, and overall maintenance costs.
How Does Total Productive Maintenance Work?
For a manufacturing company to implement total productive maintenance, it must first understand how the system works. TPM solution is a holistic strategy for maintenance that focuses on maximizing equipment productivity and reliability to achieve perfect production.
It depends on the 5S methods, which enable organizations to organize and standardize maintenance procedures, which enhances production and workplace quality. 5S TPM principles aim for workspace organization and cleanliness, promoting a safe and productive environment to work. By incorporating the 5S methodology, organizations can establish a strong foundation for effective maintenance practices, asset reliability, and workspace safety, enabling organizations to maximize equipment effectiveness and overall operational performance.
The 5s Total Productive Maintenance Methodology
The first step in the 5S methodology is to sort through items in the organization and eliminate excess clutter or items not essential for operations. With this principle, Total Productive Methodology eliminates unnecessary assets or materials responsible for organizational safety hazards or inefficiencies. This method enables organizations to optimize space and resources while improving asset accessibility and maintenance efficiency.
Set in Order
Once you sort the items next step is to organize and arrange the remaining assets logically and ergonomically. This 5s TPM principle involves creating proper storage for tools, spare parts, maintenance-related assets, and documentation. Having well-set documentation or layout makes it easier for maintenance personnel to track and access the equipment or items, reducing the time to search and retrieve objects and enhancing the overall maintenance effectiveness.
This 5S principle emphasizes cleanliness and regular maintenance of the organization. Total Productive Methodology believes in providing a clean and well-maintained environment to prevent asset malfunctions, identify potential issues, and create a safe and effective work environment. Regular cleaning, inspection, and lubrication ensure the equipment’s reliability, detect abnormalities, and prevent safety hazards.
Standardization establishes clear procedures, work standards, and visual controls to sustain the gains achieved through the first three steps of 5S. In the context of TPM, standardizations involve creating standard operating procedures (SOPs) for asset maintenance activities, ensuring that asset maintenance tasks are consistently performed based on established standards. Standardization streamlines maintenance processes while reducing variability and maintaining consistency.
The final step in the 5S TPM methodology emphasizes the requirements to sustain the progress achieved by continuously reinforcing the practices and principles of previous actions. Maintaining a pattern of continuous enhancement and disciplined maintenance practices in Total Productive Methodology is crucial. It includes ongoing training sessions, regular audits, performance reviews, and employee engagement to ensure that the principles and practices of productive maintenance and 5S methodology work effectively over time.
The Benefits of TPM in Manufacturing
Total productive maintenance is a proactive maintenance strategy that seeks to maximize the efficiency of manufacturing equipment and systems. Productive maintenance aims to prevent equipment failures and downtime while reducing the need for repairs and maintenance.
There are many benefits, but three of the most important are that it can help:
- Increase Equipment Availability: Increased availability is TPM management’s most apparent benefit. Regularly maintaining and repairing equipment can reduce the time it spends out of service. In turn, this leads to increased production and profits. One study found that It can increase factory capacity by up to 30%.
- Reduce Downtime: Reduced downtime is another critical benefit of Total Productive Maintenance. When equipment breaks down, fixing it takes a while–which means losing production time and money. You can carry out regular maintenance that will prevent most breakdowns from happening in the first place by implementing a TPM solution. As a result, your factory will experience less downtime and greater efficiency.
- Improve Quality: A well-maintained equipment is less likely to break down and cause defects in the finished product. In addition, regular servicing uncovers potential problems before they become severe enough to affect quality. As a result, It can lead to fewer defects and happier customers and improve product quality.
How to Calculate Total Productive Maintenance?
Organizations embed maintenance strategies as a fundamental approach to enhance operational efficiency, maximize equipment availability, and exclude losses. It is essential to calculate various vital metrics and formulas to calculate productive maintenance in an organization.
The evaluation of OEE is necessary to calculate the TPM, as it involves measuring three essential metrics: Performance, Availability, and Quality Rate.
OEE = Availability × Performance × Quality
Availability measures the period when the machinery is productive versus non-productive due to planned or unplanned downtime. It represents the percentage of time that asset is available for production.
Availability = (Operating Time – Equipment Downtime)/ Operating Time
Performance is about determining how efficiently an asset operates in an active state. Performance efficiency measures the asset’s speed compared to its ideal maximum speed.
Performance Efficiency = (Ideal Cycle Time × Total Count) / Operating Time
Quality Rate determines the ratio of production meeting the anticipated standards. It represents the percentage of products that meet the required quality standards.
Quality = Good Count / Total Count
Total Productive Maintenance is a set of asset maintenance and enhancement practices rather than estimated as a single numeric value. It focuses on maximizing asset effectiveness, minimizing downtime, and optimizing productivity. While there is no specific formula or numerical calculation for TPM, the success of its implementation is measured by improvement in asset effectiveness, reduction in breakdowns, enhanced productivity, improved maintenance efficiency, and overall performance of the organization.
The 8 Pillars of TPM in Manufacturing
Total Productive Maintenance aims to keep all aspects of the plant running at its highest performance levels while maximizing safety, quality, and efficiency. It is a philosophy of maintaining and improving the equipment used in manufacturing.
To Achieve these Results, TPM management focuses on Eight Key Pillars:
Autonomous maintenance empowers the operators to take responsibility for scheduled asset care. This pillar emphasizes empowering workers to care for their machines and equipment. It aims to develop a sense of ownership and pride in their asset by involving operators in maintenance.

Focused improvement involves identifying the underlying causes of problems and developing practical solutions. Organizations can reduce downtime, eliminate waste, and achieve higher productivity and quality by focusing on continuous improvement with focused improvement and total productive maintenance pillars.
Planned maintenance focuses mainly on establishing a systematic method of creating scheduled maintenance activities rather than waiting for assets to break down with the TPM solution. It includes creating a complete maintenance plan according to asset condition, usage, and manufacturer’s recommendations.
The goal is to regularly perform the maintenance activities like predictive maintenance, preventive maintenance, inspections, and parts replacements to prevent unexpected asset breakdowns or failures. It enables organizations to increase asset reliability. With the TPM in manufacturing, planned maintenance needs careful scheduling, documentation, and observance to ensure that the assets remain in optimal condition and operate effectively.
Quality maintenance is one of the pillars of total productive maintenance that incorporates quality management principles into maintenance tasks. It ensures that the organization’s end products meet or exceed customer expectations. It considers identifying and correcting the issues within the products before they reach customers.
Quality maintenance in TPM conducts regular inspections, addresses the abnormality or problems in the assets, and implements measures to prevent defects during maintenance operations. Quality maintenance emphasizes the significance of accuracy, cleanliness, and reliability. Incorporating quality management practices into maintenance activities in organizations can reduce product defects, enhance efficiency, and improve overall product quality, increasing customer satisfaction and competitiveness.

The organization investing in training and education improves the confidence and competence of its maintenance personnel, leading to higher asset reliability, decreased downtime, and improved overall maintenance performance.
The office’s total productive maintenance focuses on the administrative and support functions within the organization. It extends the maintenance concept from the production to non-production areas to streamline office operations. It aims to improve efficiency and productivity while eliminating waste in administrative processes and tasks. The office TPM solution principles will help organizations to achieve enhanced communication, workflow, and accuracy while reducing the lead times throughout the organization.
Safety, Health & Environment (SHE)
The Safety, Heath & Environment pillars focus on ensuring a safe and healthy workspace. This pillar incorporates safety protocols, health measures, and environmental considerations into the maintenance practices and operations. TPM solution identifies and eliminates hazards, promotes safety training, and employee safety procedures are safety programs to prevent organizational dangers and injuries.
Health involves promoting employee well-being, addressing ergonomic concerns, and availability of adequate personal protection equipment. Environmental aspects aim to reduce the impact of operations on the environment through energy conservation, waste reduction, and liable resource management. Prioritizing the SHE principles in total productive maintenance enables the organizations to enforce the safety rules and regulations, ensuring the proper disposal of hazardous materials and more.
Administration & Management System
To ensure the success of the seven pillars, administration and management systems need to be in place to track goals and progress. It also includes quality management systems such as ISO 9001 certification, which can help demonstrate a commitment to excellence in manufacturing processes. Effective administration and management practices are essential for supporting and sustaining TPM initiatives within an organization.
This practice involves the establishment of clear roles, responsibilities, and processes for productive maintenance implementation. It ensures effective communication and coordination, offers required resources and support and sets performance metrics for total productive maintenance implementation. A well-defined administration and management system enables organizations to align maintenance goals with overall organizational objectives, enables effective decision-making, and ensures the integration of TPM principles into daily operations.
