For example, if a product is consistently assembled incorrectly, it might be due to insufficient training on the assembly process.

Motivation and Attitude

Low motivation and negative attitudes can also cause problems. Questions to ask include: "Is the person motivated to do the task well?" and "Are there any personal issues affecting their performance?"

For instance, high employee turnover in a customer service role could be due to low motivation and dissatisfaction with the work environment.

Process-Related Categories

This category examines the steps involved in a process and how they might contribute to a problem. It includes aspects like methods, equipment, materials, and measurements.

Methods and Procedures

Inefficient or incorrect methods and procedures can lead to problems. To identify these, ask: "Are the right methods and procedures being followed?"

Equipment and Materials

Faulty equipment and poor-quality materials can also cause issues. Questions to ask include: "Is the equipment in good working condition?" and "Are the materials of good quality?"

For instance, if a machine frequently breaks down, it might be due to poor maintenance or using substandard parts.

Environment-Related Categories

This category looks at the physical environment and external factors that might contribute to a problem. It includes aspects like workplace conditions, noise, lighting, and even external regulations.

Workplace Conditions

Unsafe or uncomfortable workplace conditions can affect productivity and quality. To identify these, ask: "Are the workplace conditions safe and comfortable?"

For example, if employees are frequently injured, it might be due to unsafe workplace conditions.

External Factors

External factors like regulations, market trends, and customer demands can also cause problems. Questions to ask include: "Are there any external factors affecting the process?" and "Are we complying with relevant regulations?"

For instance, changes in customer preferences might require a company to modify its products or services.
