Not necessarily, even before having all these models, I spent most of my time thinking rather than coding. The coding part is just the final nail, that's my approach at least.
Well, to be honest it's kind of like that 90% of the time. You don't actually become more productive but end up cleaning trash most of the time. Anyway, the hardest part is connecting all the pieces properly and understanding how everything fits, handling edge cases, and so on. Writing the code itself is actually the easy part.
