I first heard Martin Hinckley speak at an AACC forum. That talk was published in Clinical Chemistry, 1997;43:873-879.
A new article is available at http://www.springerlink.com/content/y5m227582854220k/fulltext.pdf (I suspect this link will work for a limited time).
This article deals with automation and how it has not lived up to the expectation that it would greatly improve quality. Hinckley offers some interesting advice regarding how to improve the implementation of automation.
