Yes, though my answer may not help you. I too have been in your situation. If there is a solution to your immediate problem, it is one which requires as little exertion or deviation from those already involved, and one which addresses your ultimate concern… a culture of knowledge which may be reflected upon in time of need where ever the colossal requirements of your work falls upon any one of you to handle its’ exceptions. In an age threatened by automation, let our exception handling set us apart! Practically, your screwed. I have empathy for your passion. Abandon ship, in ten years you will be a greater Man who will simply not repeat this problem. For now, if you went “occult knowledge management” (yes, been there.) you must through will assert among disparate interests using motivations only equatable in benefits to minimally participate in workflows capable of capturing such knowledge as you seek. This knowledge must be processed. An additional individual (or “core” depending upon how committed you are) will be required. You may not delegate this new burden upon any who is not chiefly rewarded for its success. Good luck. Despite mass layoffs, true skill and passion for knowledge integrity is ever lasting.
