When I worked on my start up, We built our complete hardware and then software for it. I had to write down the drivers, and display library for the 128 x 64 lcd display with a simple scheduler, FSM and all!(Hard to mention all the work) Bulk of the work I did was using paper, eraser and pens. A lot of work in unchartered territory requires paper work. I realized the more I worked on paper the more correct the code was and overall it took faster to write(given fewer bugs).
