Question

Briefly discuss how the funnel experiment and tampering relate to the Deming Chain Reaction.

Answer 1

The funnel experiment explains the contrary effects of having process changes with no study of the probable process variation causes. This “worsening” efforts are referred as “tampering”. Considering the physical experiment, as marble is used to dropped through a funnel over the paper sheet as a target, with the aim to stop the marble as close as to the stated target. While experimenting, various adjustments are done due to the resulting target variations. Thus, the experiment rules can be applied in many situations, such as , making changes with no use of control charts, process adjustment needed when the outcomes are out of the range based on the need, change in organizational policy based on the feedback received from the employment survey, use of previous budget variances to have the new goal setting for business, etc. For example, periodic calibration with respect to the standard and adjusting the values to compensate the error.
