Per our discussion on Wednesday, here is a technology to improve productivity, cited by Drucker and others, as a the central objective of management science. In sum, SDS is the only way to effectively use many of the practices advocated by Drucker and others, and it provides new capabilities that greatly increase the chances for success. The review of Mr. Drucker's book, ref a, shows a how SDS is used for research.

Thanks for your consideration.

Sincerely,
