[quote]So if a Bain employee, for example, know's that Bain has worked in the past with a bicycle manufacturer and said employee is currently consulting with a sailboat manufacturer, and the production of sailboats and bicycles happens to be very similar, then he should look through Bain's files from the bicycle manufacturer to better inform him how to help the sailboat manufacturer so long as he never tells the sailboat manufacturer any sensitive/proprietary information? [/quote]Yes of course. Not only should he do it from a best practice POV, the client is paying for it to happen.
