Increase efficiency in your facility with Lean tools and techniques.

Understanding and Implementing Jidoka

Defects are a common problem often encountered in manufacturing departments. Many people in the industry have dealt with countless defects in products or machinery.

The meaning of Jidoka is “automation with a human touch”; it is Japanese terminology and is a basic idea in lean manufacturing. It means combining human intelligence with machines that stop automatically when something goes wrong. This way, problems can be fixed immediately, ensuring high quality and efficiency in production to achieve the goal of lean manufacturing which is to create value while cutting down on waste.

What is Jidoka and its Origin

Jidoka is also known as autonomation which means automation with human intelligence. It is one of the core principles Toyota introduced in the Toyota Production System (TPS), alongside Just-in-Time Production. The concept started in the 1900’s by Sakichi Toyoda, founder of the Toyota Group. At that time, Toyoda invented a loom that automatically stopped if a thread broke. Before this, looms would produce defective cloth without stopping; thus, requiring constant human attention.

This innovation by Toyoda improved production efficiency and reduced manual control needs. Jidoka has gradually changed over time and became one of the foundations on which TPS was built later in the mid-20th century with Taiichi Ohno and Eiji Toyoda further developing it.

TPS went further than Jidoka by incorporating means to detect problems and fix them instantly. Workers could stop production whenever any hitch occurred so that only good quality products were released into markets. Starting from a simple automatic loom, Jidoka lean method has now grown into a sophisticated quality control system that plays an essential role in Lean manufacturing principles to enhance efficiency across industries.

Jidoka in Practice

This Jidoka autonomation principle of lean prompts machines to stop the manufacturing process when there’s a problem. This helps fix the issue quickly to avoid making lots of defective products.

We can use sensors to automatically stop the machines if they find a problem with a product. Or, if the workers are checking things manually, they can use special tags that stop the machines if they find something wrong.

Core Principles of Jidoka

Understanding these pillars is important for effectively implementing Jidoka in your business. Here’s a breakdown of each element to enhance your comprehension of this principle.

Discovering Irregularities

Each machine should have the capability to identify errors and deviations. An alert system should be in place to notify personnel promptly about detected abnormalities, such as defects, machinery malfunctions, or material errors. This approach helps prevent the production of large quantities of defective items.

Stop the Production Process

Upon detecting potential irregularities, machines should automatically cease production to prevent the further manufacture of flawed products. This pause allows time to rectify the issue and prevent its recurrence. Operators should also have the authority to manually halt production if they detect a problem.

Taking Corrective Measures

With production halted automatically, operators can evaluate the situation and seek immediate assistance if needed. They should then proceed with corrective actions within a specified timeframe to resolve the issue. Additionally, they must decide whether to resume production based on the situation’s assessment.

Preventing Future Occurrences

Following corrective actions, preventive measures should be implemented to reduce the risk of recurrence. This may involve training programs for operators on proper equipment usage or introducing new quality control protocols.

What are the Benefits?

Jidoka is the best principle for modern manufacturers, helping them make better products efficiently. Let’s look at the advantages:

  • Early problem detection and resolution: Identifies issues promptly to prevent complications and disruptions.
  • Improved overall productivity: Minimizes production cycles and downtime, leading to increased efficiency.
  • Zero defects: Halts production upon detecting abnormalities, ensuring high-quality products.
  • Lower production costs: Reduces waste and streamlines processes, resulting in decreased expenses.
  • Built-in quality control: Integrates quality checks into the production process, reducing the need for separate inspections.
  • Reduced reliance on manual inspectors: Automated self-diagnosis and correction minimize the need for manual inspection.
  • Increases employee morale: Empowers employees to address emergencies, boosting morale and engagement.
  • Lower equipment maintenance costs: Timely intervention mitigates minor equipment malfunctions, reducing maintenance expenses.
  • Reduced need for additional staff: Enhanced operational efficiency allows fewer staff to manage multiple tasks effectively.
  • Prevention of problem recurrence: Implements corrective measures to prevent the recurrence of issues, ensuring sustained quality and operations.

How To Implement Jidoka?

Follow these simple steps to successfully implement Jidoka and foster a culture of continuous improvement and excellence.

Step 1: Show Commitment from Management

Management commitment is important for successful Jidoka implementation. Leaders need to not only express support but also allocate resources and actively participate in planning and implementation.

Step 2: Spread the Jidoka Message

After management commitment, it’s essential to communicate the purpose and benefits of Jidoka throughout the organization. This ensures everyone understands how it aligns with company goals and contributes to quality and efficiency.

Step 3: Conduct Readiness Assessment

Assess the organization’s readiness for Jidoka implementation by evaluating processes, systems, and workforce skills. Identify areas for improvement and develop strategies to address them.

Step 4: Implement Practical Solutions

Once readiness is confirmed, start applying Jidoka principles in daily operations. Identify areas for improvement, then design and implement solutions to detect and address issues automatically or alert operators when necessary. This ensures defects are prevented, leading to better efficiency and product quality.

Challenges of Implementing Jidoka

Implementing Jidoka in a manufacturing setting can come with pose a few challenges which include:

  • Change Resistance: Some workers might not be comfortable with the new way of doing things. It’s important to explain the benefits of Jidoka and address employee concerns.
  • System Integration: Making the automation work with the current systems and processes might take a lot of time and effort. Plus, investing in new machinery and training programs can increase short-term operational expenses.
  • Training Needs: Employees may need advanced training to understand how to use the automation tools and systems.
  • Management Support: Managers need to completely understand Jidoka and be committed for it to work well.
  • Assessing Readiness: Before implementing this principle, it’s a good idea to check if the company is ready for it. This helps find any problems that might get in the way.

Continuous Improvement with Jidoka

To build a structured framework for enhancing Jidoka practices, schedule periodic reviews to assess their effectiveness. You can also implement feedback mechanisms to gather input from employees at all levels of the organization.

Evaluate new technologies, such as sensors, automation systems, and data analytics tools, continuously to determine how they can be integrated into existing processes to improve efficiency, accuracy, and reliability.

It is important to provide employees with training and development opportunities to ensure they have the necessary skills and knowledge to implement and utilize Jidoka practices. Additionally, clear documentation and standard operating procedures must be established to ensure consistency and alignment across the organization.


Integrating autonomation principles into production marks a big change in how things are done nowadays, adding independence, a focus on quality, and making things more efficient in manufacturing. As industries adapt to the need for accuracy and dependability, Jidoka’s ideas offer a forward-thinking approach to achieving long-term superior performance.
