Statistical Process Control
Statistical Process Control (SPC) is a method used in manufacturing to monitor and improve product quality. It's like having a quality detective that watches how products are made and catches problems before they become serious. Instead of checking every single product after it's made, SPC uses math and charts to spot patterns and trends during production. This helps factory workers and managers know when machines need adjustment or when something isn't working right. It's commonly called "SPC" for short, and similar terms include "Process Control" or "Quality Control Methods." This approach is especially important in automotive manufacturing where consistency and safety are crucial.

Example Interview Questions
Senior Level Questions
Q: How would you implement an SPC program in a factory that has never used it before?
Expected Answer: Should discuss training needs, selecting critical measurements, establishing baselines, choosing appropriate control charts, and creating standard procedures. Should mention importance of employee buy-in and management support.
Q: How do you handle resistance to implementing new quality control methods?
Expected Answer: Should explain approaches to change management, training programs, demonstrating benefits through pilot programs, and involving workers in the implementation process.
Mid Level Questions
Q: What kinds of charts would you use to monitor different types of data?
Expected Answer: Should be able to explain when to use basic chart types like X-bar charts for measurements and P-charts for pass/fail data, in simple terms.
Q: How do you decide what process measurements are most important to monitor?
Expected Answer: Should discuss identifying critical product features, customer requirements, and past quality issues to determine what needs closest monitoring.
Junior Level Questions
Q: What is the purpose of control limits in SPC?
Expected Answer: Should explain that control limits help determine when a process needs attention, like warning lights that show when something is starting to go wrong.
Q: How would you explain SPC to a machine operator?
Expected Answer: Should be able to simplify SPC concepts into practical terms, explaining how it helps catch problems early and maintain product quality.
