What I learned as developper and Data Scientist is: either you know what you’re doing and can see the big picture, either you’re walking blindly to a “good enough” solution. In the first case, I spend most of my time in architectural design and modelization. The implementation phase is rather quick, because everything is well defined and you can write a lot of tests upfront. In the second case, you’ll discover the big picture by facing the problems while trying to find and implement a working solution. While getting experienced means how fast can you figure out the big picture.
