How Much Detail On A Process Map?

The maps below show two levels of detail. The upper map shows individual elements within a workcell such as Head Subassembly and Body-Coil Subassembly. It also shows the moves and delays between these elements within the cell. 

The lower map explodes the Head Subassembly operation into smaller elements. Even this map could conceivably be exploded into micro-motions, but there is not much point in doing so.

At an even higher level than shown below, all assembly operations would compress into the single element, "Assemble Pump." Such a map would work well in sorting out product families.

The first map, below, would be appropriate for workcell design while the second map would help workstation design.
