In this two-day, hands-on seminar, participants first gain expertise using NWA Quality Analyst while applying statistical quality control techniques in classroom exercises. The class then works in teams to solve problems in a simulated manufacturing process. Attendees learn how to maximize their use of NWA Quality Analyst as well as exploit the advantages of the Windows environment.

Applying SPC to a Simulated Process

• Class divided into small teams to solve quality problems in simulated factory
• Teams collect data, interpret results, and convince management (the instructors) of necessary changes by presenting compelling charts and clear explanations
• Highly realistic simulator responds to process adjustments and improvements
