I had the pleasure of speaking with Chris Winter today, proprietor at SkillsCrafters.com. He's developed a method over many years enabling him to catalog training content by using a spreadsheet. He's worked with organizations like GM, MillerCoors, The U.S. Navy, and The U.S. Coastguard.
I don't usually get involved in the nitty-gritty of content compilation, but for huge learning interventions, this must be a massive challenge.
I can handle the vast learning-research literature -- and find it fun to do so -- but I'm glad there are folks like Chris who have the patience to organize the content.
Check him out at the Skills Crafters website.
