Spread across 10h 30m of on-demand video, that works out to roughly $0.95 per hour of content — less than the cost of a single chapter of most printed business textbooks.

A discount is only worth something if the material delivers, and the curriculum here is built around practical outcomes. Ray Harkins and The Manufacturing Academy walk you through root Cause Analysis, the 8D Corrective Action Process, and quantitative tools such as Capability Analysis, Control Charts, MSA, Regression Analysis and more — concrete skills you can apply, not abstract theory.
