Thirty years ago when you needed to install new computers in an office I remember it took us weeks to get the cable (Ethernet) installed because one contractor had to pull the cable and cut it at each workstation, another contractor had to come and put the connector on the cable and yet another had to come and plug the cable into the machine. Believe me we were tempted to sneak in one weekend and do the whole thing ourselves but were severely warned about the consequences. So what could have been done in a day by one or two guys took over a month because you couldn't even schedule the second service until the first was done. I imagine this kind of thing is everywhere when it comes to building real infrastructure.
