Sketch out the plan broadly at first (e.g., “hire great people”) and then refine it. You should go from the big picture and drill down to specific tasks and estimated time lines (e.g., “In the next two weeks, choose the headhunters who will find those great people”). The real-world issues of costs, time, and personnel will undoubtedly surface as you do this, and that will lead you to further refine your design until all the gears in the machine are meshing smoothly.
