The FPY (First Pass Yield), or First Pass Yield, is a fundamental indicator of the efficiency and quality of a test or production process. It measures the percentage of units that pass the test on the first attempt, without the need for rework, repetition, or correction. Why is FPY important?
The analysis of test result stability is an essential methodology to ensure that a test system continues to deliver reliable, repetitive, and consistent measurements over time. This practice is fundamental to maintaining the reliability of the production process and avoiding false failure diagnoses. 🧪 Why is result stability so important?
A bottleneck is any step in the production process that limits the overall flow. It acts like a funnel, reducing the line speed and directly impacting productivity, quality, and delivery time. In a production line, efficiency is defined by the slowest step. Identifying and eliminating the bottleneck is essential for
PPM means Parts Per Million (in English Parts Per Million) and is a metric used to measure the defect rate in a production process or testing system. PPM indicates how many defective parts exist per million units produced, being one of the main performance indicators in quality. The lower the
