In two cities, I had major cable TV problems at my house.
Each case involved 8-10 visits by all sorts of trained (and untrained) technicians at an average cost to the cable company of $100/visit.
In both cases, the problem was a frayed $3 wire — which could have been fixed in 10 minutes.
But nobody looked.
It wasn’t in their job description. They were in the wrong union. They assumed someone else checked it.
Who is responsible for checking the obvious at your company?
Where is the checklist to make sure the simplest stuff isn’t skipped?
