Do Not Create DSL for the Customer (2015)

"Why do most of the DSL projects fail then?

What I see is that most of these project implement first the switch on the wall and the outlet to plug in the TV, washing machine and so on but then they start to go on and try to invent other tools that would support the reorganization of the wiring. Someting like a cross connection table at the electric center of the house where the customer can plug in wires to have 12V direct current in some of the outlets, 120V alternating current in other outlets and 220V in the guest room when visitors come from Europe.

I hope you get the point: DSL solutions become just too complex for the customers. First it starts off with a simple text file. Later on it is an Excell table. Then a whole buch of sheets with many columns. Even later somehow scripts emerge that help the editing and the conistency maintenance of the data. And it all supposed to be maintained by the customer.
