Tlg India Quality Engineer Interview Questions, Process, and Tips

Quality refers to the degree of excellence or superiority of a product or service.

• Quality is a measure of how well a product or service meets customer expectations and requirements.

• It involves ensuring that the product or service is free from defects or errors.

• Quality also includes aspects such as reliability, durability, performance, and customer satisfaction.

• Quality can be achieved through various processes like qual...read more

Defect control can be achieved through various methods such as statistical process control, root cause analysis, and continuous improvement.

• Implement statistical process control to monitor and control the production process

• Conduct root cause analysis to identify the underlying causes of defects and implement corrective actions

• Implement continuous improvement initiatives to prevent defects from occurring in the first pl...read more

To control the defect problem, use 7QC tools and TQM.

• Identify the problem and gather data using tools like Pareto chart, Ishikawa diagram, etc.

• Analyze the data to find the root cause of the problem.

• Develop and implement a solution using Total Quality Management principles.

• Monitor and control the process to ensure the problem does not recur.

• Continuously improve the process to prevent future defects.

PDCA stands for Plan-Do-Check-Act, a four-step management method used for continuous improvement of processes and products.

• Plan: Identify the problem and plan a solution

• Do: Implement the plan

• Check: Evaluate the results and compare them to the expected outcomes

• Act: Take corrective action and make necessary adjustments for improvement

• Example: Using PDCA to improve a manufacturing process by identifying the problem, imple...read more

7QC tools are a set of basic quality tools used for process improvement and problem-solving.

• The tools include: Pareto chart, cause-and-effect diagram, check sheet, control chart, histogram, scatter diagram, and flowchart.

• They help identify and analyze problems, prioritize issues, and monitor progress.

• For example, a Pareto chart can be used to identify the most common causes of defects, while a control chart can be used

Various quality tools can be used to solve problems in product checksheet, pareto diagram, fishbone diagram, histogram, scatter diagram, process flow diagram, and control chart.

• Checksheet can be used to collect data and identify patterns.

• Pareto diagram can help identify the most frequent problems.

• Fishbone diagram can be used to identify the root cause of a problem.

• Histogram can help identify the distribution of data.

• Sc...read more

Measuring instruments are used in quality to ensure products meet specifications and standards.

• Measuring instruments help to accurately measure and monitor product characteristics such as dimensions, weight, and strength.

• They are used to ensure products meet specifications and standards set by regulatory bodies and customers.

• Examples of measuring instruments include calipers, micrometers, gauges, and spectrophotometers...read more
