For some 1 year or so, I had a dept head, with whom no serious exchange of strategy or methods was possible. Climax was when trying to discuss the appropriate stock level and his proposal was to let our stock hit 0, just to have a nice clear stock sheet. Things worked out much better when I started adapting conversation in a way I`d do with elementary school kids. Then he was transferred, and now the new dept head luckily is someone who`se fully capable and grasps enough info in a 30 seconds tel call. The present head of dept though seems to be less polular with higher management, LOL, probably because too dificult to understand for them.
