Design of Experiments (DOE) with Minitab

Overview of the Course
Design of Experiments is an off-line quality improvement technique that can be employed to dramatically improve industrial products and processes. Through its use, it is possible to isolate the cause and effect linkages between product/process variables and the resulting output measures of function, quality, cost and performance.

This intensive course provides participants with in-depth understanding of the basic principles of experimental designs. Actual examples are emphasized throughout the presentation.  Participants are taught how to use screening designs (fractional factorials) to identify important factors, along with characterization designs (general factorials and 2^k factorials) for assessment of main effects and interaction. Use of games such as helicopters and unique simulation exercises accelerates the learning process and makes the learning process fun for the engineer.

Knowledge of DOE and the ability to effectively use DOE are basic requirements of modern engineering.  This course equips the engineer to effectively plan, execute, analyze and interpret DOE’s.

This course does not teach participant on just how to point and click. The basic concepts underlying each tool are discussed before the use of the software is demonstrated.

Participants :      Managers and Engineers from all engineering disciplines including Process, Research and Development, Quality, Maintenance and Reliability.
