Alstom Transportation Interview Questions and Answers

KPIs in quality assurance measure performance, efficiency, and compliance to ensure product quality and process improvement.

• Defect Density: Measures the number of defects per unit of product. For example, 5 defects per 100 units produced.

• First Pass Yield (FPY): Percentage of products that pass inspection without rework. For instance, 95% FPY indicates high quality.

• Customer Complaints: Tracks the number of complain...read more

FMEA is a systematic approach to identify potential failure modes and their effects, linked to control plans for risk management.

• FMEA stands for Failure Mode and Effects Analysis, a proactive tool used to identify and prioritize potential failure modes.

• It involves assessing the severity, occurrence, and detection of each failure mode to calculate a Risk Priority Number (RPN).

• For example, in a manufacturing process...read more

Quality problem-solving tools help identify, analyze, and resolve quality issues in processes and products.

• Root Cause Analysis: Identifies the underlying cause of a problem, e.g., using the 5 Whys technique.

• Fishbone Diagram: Visualizes potential causes of a problem, helping teams brainstorm solutions.

• Pareto Analysis: Focuses on the most significant issues by identifying the 'vital few' causes that contribute to th...read more

Use a set to keep track of unique numbers while maintaining original order.

• Iterate through the array and add each number to a set if it hasn't been encountered before.

• Create a new array by iterating through the original array and only adding numbers that are not in the set.

• Return the new array with duplicate numbers removed.
