I tend to get given large projects to do. I'm fairly senior, and once we've got past the brainstorming stage, the ideas have flowed forth, and the direction is, if not clear, then at least aspirational, I often get given the job of breaking ground. Here's how I think. I model interaction between distinct parts. I have a mental model of how X fits with Y, how X can affect Y, and how Y can in turn affect X. I'm not doing it with just X and Y, I painstakingly build this mental model[1] over as much of the problem space as I can, and having done this for many years now, I can cover a fair amount of ground before the complexity gets beyond my ability to model. It takes a while to create this, and then when some middle-management type wanders along, taps me on the shoulder and disturbs the concentration, and it all comes crashing down around me, I am less than best-pleased. Bonus points if it's just to "touch base" or "remember we have a meeting in 2 hours time", or ... you get the picture. Why do I expend this enormous mental effort to gain such a fragile and ephemeral state ? Because I can mentally throw boundary conditions at it and "see" how things will react. It's how I deal with inherent complexity of large systems, and a couple of hours of mental effort can prevent me spending a week coding down a dead-end path. It's happened often enough now that even my line management understand it's worth the time - there's been plenty-a-meeting where I go in and say "yeah, I know we wanted to do <insert X> but I think there's a problem when Y and Z come into play under conditions A, B and C. I think <insert option gamma> is a better route even though we didn't think so at first". Sometimes you really do just need to be able to be left alone and think. As someone who used to own the company before he sold it, and who's done pitches to VC's and other investors, I can quite categorically state that (for me), the slides, presentations, and client management is nowhere near the level of mental investment. Nowhere near. Just my $0.02 --- [1] It's not visual, I have aphantasia, it's more firing-condition-based. |
