Process Validation
Process Validation is a systematic way of making sure that manufacturing processes consistently create products that meet quality standards. It's like having a detailed recipe that must be followed and proven to work every time. In electronics manufacturing, this involves checking and documenting that assembly lines, equipment, and procedures reliably produce electronic components or products that work correctly. Companies need this to satisfy customer requirements and meet regulations, especially in industries where product failure could be dangerous or costly. Other terms for this include "manufacturing process validation" or "production line qualification."

Example Interview Questions
Senior Level Questions
Q: How would you handle a process validation failure in a high-volume production line?
Expected Answer: Should explain systematic problem-solving approach, including investigating root causes, implementing corrective actions, revalidating the process, and updating documentation while minimizing production impact.
Q: Describe how you would establish a new process validation program from scratch.
Expected Answer: Should discuss creating documentation systems, setting up testing procedures, training staff, establishing acceptance criteria, and ensuring regulatory compliance.
Mid Level Questions
Q: What are the key elements of a process validation protocol?

Junior Level Questions
Q: What is the difference between IQ, OQ, and PQ in process validation?
Expected Answer: Should explain Installation Qualification (checking equipment setup), Operational Qualification (testing if it works), and Performance Qualification (checking consistent results) in simple terms.
Q: What documentation is typically required for process validation?
Expected Answer: Should mention basic documents like protocols, test results, reports, and standard operating procedures (SOPs).
