First pass yield (FPY) is a measure of the quality of a process or system, expressed as the percentage of units that are produced correctly on the first try. It is a key performance indicator (KPI) that is used to evaluate the effectiveness of a process or system in producing output that meets quality standards.
To calculate FPY, the total number of units produced is divided by the number of units that are produced correctly on the first try. For example, if a process produces 1,000 units and 900 of them are produced correctly on the first try, the FPY would be 90%.
FPY is important because it can impact the efficiency and effectiveness of a process or system. High FPY indicates that the process is producing high-quality output with minimal defects or errors, which can lead to cost savings and improved customer satisfaction. Low FPY, on the other hand, may indicate that the process is producing a high number of defective or nonconforming units, which can lead to increased costs and reduced customer satisfaction.
To improve FPY, organizations may need to identify and address the root causes of defects or errors in the process. This may involve implementing quality control measures, improving training and education for workers, or investing in new equipment or technologies. By continuously monitoring and improving FPY, organizations can optimize their processes and improve the overall quality of their output.
