The company I work for tried that... and still tries. First attempt was scanning everyone's file cabinets and putting that information onto a big server where it cannot be accessed. Then they started having the "senior emertitus engineers/scientists" tell their story verbally -- both taped and in storytelling lunch sessions. All that really did was reveal that these guys who once had brilliant careers have become doddering old fuddy-duddies who were lost in the past with little understanding of how to recreate "the good old days" or, more importantly, do the good work of the past in the new technological and economic conditions. It is a concept that is much better sounding on paper (or on an internet forum) than it is in real life.
Even the youngest most bright eyed individual worker at EK, or retiree, will not get involved in this kind of work. All formulas are documented and backed up, but in the end, no-one knows the entire formula at any one time AFAIK.
