On a recent road trip, it struck me how often the provincial and local maps' road number designations did not correlate with physical road signs. Chalking it up to budgetary constraints hindering the placing of signs, I remembered a phenomenon I call 'but the locals know'.
The map shows we needed to get north onto provincial route 37, transferring in the town of Elmin. We got to Elmin's major lighted intersection - but no route signs are there. Ah - a police car happens by and we roll down windows to hear that "route 37, that would be Elmin Shore Road, back 2 blocks to your left". 300 feet down that road, indeed a sign says 'route 37'.
Later that day, we came to an intersection expecting road number signs. None to be seen - but I espied by noting their shape the back of such signs kitty corner. Go straight and make a U turn and so indeed we can see the road number signs. So ... We believe the locals know ... but they are not sharing their knowledge with non-locals through signs.
Translating road sign experience to organizational work raises many questions. As an example: If new people came to do work, would clear road signs be there for them ... or would they have to rely on local knowledge? Making clear signs and relying on local lore each have a cost - up front or as it happens. What is the greater cost - making up the sign or dealing with the questions?
