Basics of the Toyota Production System and on-site applications that new employees in the production technology department should know

Understanding the Toyota Production System

The Toyota Production System (TPS) is an integrated socio-technical system, developed by Toyota, that comprises its management philosophy and practices.

The system efficiently organizes manufacturing and logistics for the automobile manufacturer, including the interaction with suppliers and customers.

The main objective of TPS is to eliminate waste and improve productivity while maintaining value.

This approach is rooted in two key concepts: “Just-In-Time” (JIT) and “Jidoka.”

Just-In-Time (JIT)

Just-In-Time is primarily about producing only what is needed, when it is needed, and in the amount needed.

The goal here is to minimize the time products are sitting stagnant at any point in the production process.

JIT aims to improve a business’s return on investment by reducing in-process inventory and its associated carrying costs.

This approach not only helps in reducing waste but also in improving the flow of materials throughout the organization.

It enhances the company’s responsiveness to customer demands, making the system dynamic and flexible.

Jidoka

Jidoka is a practice that enables machines and operators to stop work immediately when a problem is found.

The principle is that quality should be built into the production process.

When a mistake is detected, production is halted and an investigation is started to find the root cause.

This approach ensures that defective products are not passed to the next stage in production.

The benefits of Jidoka include increased quality assurance and reduction in potential defective products reaching the customer.

On-Site Applications for New Employees

For new employees in the production technology department, it’s crucial to understand how TPS is applied on-site.

These applications are not only theoretical concepts but practical guidelines that must be implemented consistently.

Value Stream Mapping

Value Stream Mapping is a tool that allows the visualization of the flow of materials and information as a product or service makes its way through the value stream.

New employees should learn to map the current state and design a future state for the series of events that take a product from the beginning of the process to customer delivery.

This tool helps in identifying and eliminating waste, thus improving efficiency.

5S Methodology

5S is a workplace organization method that includes five phases: Sort, Set in order, Shine, Standardize, and Sustain.

The implementation of 5S helps in creating and maintaining an organized, clean, and efficient work environment.

It is an essential part of the TPS that contributes to waste reduction and maximizes efficiency.

Learning and applying 5S is crucial for new employees as it is a foundation for continuous improvement.

Kaizen

Kaizen, meaning “continuous improvement,” is the practice of constantly refining and improving processes.

For a new employee, engaging in kaizen means actively seeking small, incremental changes that lead to substantial improvements over time.

In practice, this involves participating in regular team meetings to identify improvement opportunities and propose solutions.

Kaizen fosters a culture where employees at all levels are contributing ideas and solutions to problems.

Practical Benefits of TPS

Understanding and implementing TPS has notable benefits for both new employees and the organization.

Waste Reduction

One of the most significant advantages of implementing TPS is the reduction of waste.

This waste includes excess inventory, unnecessary movements, and overproduction.

By adhering to principles like JIT and Jidoka, organizations minimize these inefficiencies, leading to reduced costs and improved resources utilization.

Improved Quality

TPS ensures that problems are identified and rectified at their source, thus improving the overall quality of the products.

This reduction in defects leads to higher customer satisfaction and fewer returns or recalls.

Increased Efficiency

The TPS framework leads to increased efficiency in operations.

Employees are well-versed in identifying waste, utilizing resources better, and streamlining processes, which contributes to higher productivity.

Teamwork and Employee Satisfaction

TPS promotes an environment of teamwork by involving employees at all levels in the process of improvement.

Employees feel valued as they are part of the decision-making process, which can lead to higher morale and job satisfaction.

Challenges and Considerations

While TPS is beneficial, there are challenges to consider, especially for new employees.

Change management and getting accustomed to the TPS culture can be daunting.

It requires dedication, willingness to learn, and adaptability.

It is essential for new employees to understand that TPS is a continuous process that requires ongoing commitment and effort.

Conclusion

The Toyota Production System is more than a collection of techniques and tools.

It is a comprehensive framework aimed at driving efficiency by eliminating waste and empowering operators to make quality contributions.

For new employees in production technology, understanding and implementing TPS principles is crucial.

It offers opportunities for personal development and contributes substantially to the organization’s success.

Embracing these principles sets a foundation for a successful career in manufacturing and production technology.
