Final answer:
Frederick Taylor is not considered a significant contributor to quality management theory; his focus was on improving efficiency through scientific management rather than on the principles of quality management embraced by Deming, Juran, and Crosby.
Step-by-step explanation:
The individual who was not considered to be a significant contributor to the quality management theory/movement is d) Frederick Taylor.
Frederick W. Taylor was an engineer from Pennsylvania known for advocating “scientific management” of industry, primarily through his book “The Principles of Scientific Management.” His work focused on the efficiency of production processes by conducting time and motion studies to eliminate unnecessary steps and wasted motions.
Although Taylor's work had a significant impact on management practices, his focus was not on quality management, which deals with the consistency of the production quality and continuous improvement, but rather on productivity and efficiency.
On the other hand, W. Edwards Deming, Joseph Juran, and Philip Crosby were pivotal figures in the quality management movement, each contributing important principles and methodologies that shaped the field.
