How to find root cause hai

Question

Accepted Answer

To find the root cause, use problem-solving techniques like the 5 Whys, fishbone diagram, and Pareto analysis.

Use the 5 Whys technique to repeatedly ask 'why' until the underlying cause is identified.
Create a fishbone diagram to visually analyze potential causes across different categories.
Apply Pareto analysis to prioritize potential causes based on their frequency or impact.
Collect and analyze data to identify patterns or trends that may indicate the root cause.
Consider using tools like fault tree analysis or failure mode and effects analysis (FMEA) for complex problems.
Example: If a product fails during testing, use the 5 Whys to determine that the failure was due to a faulty component.
Example: If a manufacturing process has high defect rates, create a fishbone diagram to identify potential causes like equipment, materials, or human factors.
Example: If customer complaints are increasing, apply Pareto analysis to focus on the most common issues.
Example: If a machine frequently breaks down, analyze maintenance records and collect data on failure patterns.
