The following graphs illustrate the power of the Human Calibration training method. Note how the distribution normalized for the inspection results of the company's 87 inspectors after the Human Calibration training.

Alpha inspection errors (rejecting good parts) increase operational costs.

Beta inspection errors (releasing bad parts) increase customer complaints.

Human Calibration allows companies to control operating costs while protecting the top line by giving inspectors the knowledge to release good parts while rejecting bad parts reliably and consistently.
