The business defines it as "meetings, presentations, support, coding, whatever".
Your productivity remains at 100% when you are doing what they want.
I get that you thought you were hired as a coder, and thus measure your productivity by that. That's what I thought too. I ended up doing a lot of support (which is good, but that's another thread). Until I recalibrated my definition of productivity that frustrated me. When I realized that support was productivity I got much less frustrated.
I have been on the industry for 35 years. I have seen my share of technology evolutions and o have seen the work from a dozen different dimensions. If after all that time, I find the process painful, just trust me -- they can't change me, and I can't change them. You take the warts with the wins and move on. 2-3 bad weeks, 10 good weeks. Life moves on to next quarter. Complete CEO mindset :)
I meant my other productivity drops because I am not a natural presenter so even though I am rehearsing / editing for 2 hours a day, the presentation consumes me / overwhelms me that I can't even focus for the remaining 4 hours or 2 hours. Just do the bare minimum email processing, just survive. Everyone knows it. But by being in that zone of paralysis, I can still deliver a presentation. Sometimes good sometimes ok.
I have this need for the presentation content to reside in my memory cache and other work disrupts the cache quite badly.
But that's not a way to live. The other work stalled for 3 weeks.
