We had to shut down TSO on the weekends so production could get the memory.This was a 30+ years ago and I was 'asked" to explain the issue to the data center manager. He was not lets say smart (but not dumb either). I asked if I could erase some of his white board and I was drawing pictures (I understood) and at the end I summed it up as to that is why under MVS you do not have these issues under our SVS system you did. The woman in the room was smart but she said she somewhat understood and the manager said it didn't make sense and he was lost at virtual.I went through it again and explained how DAT worked carefully this time. I got done and he said he understood it. I left feeling I had accomplished something, ahh but I hadn't. The next week I get a call to go to floor 1720(if memory serves me) with no indication who was there and what (if anything was needed). I showed up and both people were there. The DC manager explained to me that they still did not get virtual and would I explain it one more time. So I took them from ground zero to Virtual and was asking if they understood or did I have to explain again. This time both got it and was extremely pleased that I was able to get them up to speed. I said no problem and walked out of the conference room think wow I am glad I am done with that. The next week I get a call from my VP asking if I had some time this Thursday(I think) and said well how long will I need as I have something I have to do Thursday afternoon. He assured me 2-3 hours would be the max.Anyway I walk into the room where this meeting was to be held and every single programming manager was there along with some staff. I was asked to give the class to the rest of the organization. Oh great a group that will give me no end of grief. So I got up and used the white board and gave the same spiel to the management of programming. I went through the second spiel I gave the DC manager. I got only one question and that not even being close to a real question. I said wait till we are done and then I will answer the question.After I got done I asked if there were any questions and I got one or two that I had talked about but didn't understand how relocation occurred so I answered the question using the same terminology I had used the first time but this time I stepped them through exactly what was going on and all of a sudden both faces lit up and they said my explanation answered their question to a T. I asked once more if there were any questions and everybody seemed to understand. I am guessing it went really well as all the managers thanked my VP and he relayed it on to me. I got a bunch of free dinners (on the expense account but it was the thought that was important).
