The development and implementation of SOPs within the framework of TPM require a systematic approach. Here’s how organizations can standardize TPM activities through SOPs:

1. Identify Critical Processes: Begin by identifying key processes that significantly impact equipment reliability, production efficiency, and product quality.
2. Develop SOPs: For each identified process, develop an SOP that outlines the step-by-step tasks required to perform the process effectively and safely. These SOPs should be developed collaboratively with input from operators, maintenance personnel, and engineers to ensure they are practical and comprehensive.
3. Training and Education: Ensure that all relevant personnel are trained on the SOPs. Training should be hands-on, allowing employees to become familiar with the procedures and understand the rationale behind them.
4. Implementation and Monitoring: Implement the SOPs and monitor their adherence and effectiveness. Regular audits and inspections can help ensure that the procedures are followed and identify areas for improvement.
5. Continuous Improvement: Use feedback from the implementation phase to refine and improve the SOPs. Encourage employees to suggest improvements and incorporate their feedback into revised versions of the SOPs.
6. Documentation and Accessibility: Maintain up-to-date documentation of all SOPs and ensure they are easily accessible to all relevant personnel. Digital platforms can be used to facilitate access and updates.

Training in TPM with Training Within Industry (TWI)

Training is a cornerstone of Total Productive Maintenance (TPM) because it equips employees with the knowledge and skills necessary to maintain equipment effectively, identify opportunities for improvement, and contribute to the overall efficiency and quality of the production process. An effective methodology that complements TPM in this regard is Training Within Industry (TWI). Developed during World War II to support the rapid training of workers in various industries, TWI has proven to be a valuable framework for implementing structured training programs within the context of TPM.

TWI’s Role in TPM

TWI consists of three core programs: Job Instruction (JI), Job Methods (JM), and Job Relations (JR), each addressing different aspects of job training and improvement. These programs align closely with the goals of TPM, particularly in fostering a culture of continuous improvement, empowering employees to take responsibility for their machinery, and enhancing the overall productivity and safety of the workplace.

Job Instruction (JI)

Job Instruction focuses on teaching supervisors and team leaders how to train employees quickly and effectively. The JI method is particularly relevant to TPM’s autonomous maintenance pillar, as it ensures that operators are proficient in the basic maintenance tasks required for their equipment. The JI four-step method consists of:

1. Prepare the Worker: Put the learner at ease, explain the job’s importance, and establish the intent to teach the job.
2. Present the Operation: Demonstrate the task, breaking it down into manageable steps while clearly explaining each key point and the reasons behind them.
3. Try Out Performance: Have the learner perform the task, correct mistakes, and reiterate the key points.
4. Follow Up: Put the learner on their own, gradually reduce supervision, and encourage questions to ensure continuous learning.

Job Methods (JM)

Job Methods training is designed to teach supervisors and employees how to improve the way jobs are done. This aligns with TPM’s focused improvement pillar by encouraging workers to identify and eliminate waste in processes, increase productivity, and improve the use of resources. JM emphasizes breaking down jobs into their constituent steps and critically analyzing each step to find improvements. The JM four-step process includes:

1. Break Down the Job: List all job steps as currently performed.
2. Question Every Detail: Critically examine each step to identify improvements.
3. Develop the New Method: Reconstruct the job steps incorporating the identified improvements, while ensuring safety and quality.
4. Apply the New Method: Implement the improved method, train employees in it, and continue to refine the process over time.

Job Relations (JR)

Job Relations focuses on building positive relationships between supervisors and employees, which is crucial for the successful implementation of TPM. A positive work environment encourages teamwork, facilitates communication, and ensures that employees are motivated to participate in maintenance activities. The JR method teaches supervisors how to handle problems, prevent them, and earn the cooperation and respect of their team through four main principles:

1. Develop and Maintain Good Relations: Treat team members as individuals, respect their contributions, and be genuinely interested in their welfare.
2. Let Each Worker Know Their Job: Clearly communicate job details, expectations, and the importance of their role in the success of TPM.
3. Give Credit When Due: Recognize and acknowledge contributions and improvements made by employees.
4. Tell People in Advance About Changes: Inform team members about changes that will affect them, explain the reasons, and involve them in the transition process.

Implementing TWI within TPM

To integrate TWI into TPM, organizations should:

• Assess Training Needs: Identify skill gaps related to maintenance tasks, safety procedures, and improvement processes.
• Customize TWI Programs: Adapt TWI’s core programs to the specific needs and context of the organization’s TPM goals.
