I worked for a guy who was heavily involved in the science of kitchen design from a workability standpoint (we sold custom cabinets). His theory was "the triangle". Creating a triangle between the sink, oven, and counter. As it applies to the WFO: prep area, oven, finish/plating area. MY final plan is (standing in front of the oven with the grill next to it) is sink and finish on left, prep directly in front of oven on an island such that when I place the lip of the peel on the prep table, the handle rests on the oven entry.
