I don't know the details, but I do believe there has to be two sides to the story. I know people who have worked with the City on projects before that have gone completely sideways because they can't get anyone in the City to some basic information gathering that is needed to make the project successful. At some point, you just go upside down on the contract and halt work. I've also seen international companies suffer the same fate and send the City formal notification that they were removing all project resources on their side because everybody at the City was "too busy" to provide some very easy, fundamental information/work that would help the project succeed. That unwillingness to do ANY work at all forced the project to failure as it was something that only a City employee could do/know.
Siemens might have been all Siemen's fault, but I'm very skeptical of that.
I also can't imagine going backwards to in person meter reading. Can you imagine what you would have to pay someone to drive around Jackson and read meters? The chance of getting randomly shot coupled with the odds that someone takes issue with you being a part of them having to pay their water bill is too much.
The Siemens project was a failure because the city required Siemens to hire the city's preferred subcontractor, that didn't know how to do the work, to install the new meters (so the powers that be could take their cut), required Siemens to hire the city's preferred subcontractor, that didn't know how to do the work, to train the city on reading the meters (so the powers that be could take another cut), required Siemens to hire the city's preferred contractor, that didn't know how to do the work, to do all the IT work so it would all run smoothly (so the powers that be could take yet another cut), and then the city employees who were not used to doing any work, predictably didn't bother to learn to use the new system. I can't imagine why it failed.
Now we're getting new water meters, again. Rinse and repeat the above steps and watch the same results play out. The people that run Jackson are often inept, but more often the perception is that it is "their turn" to get theirs from taking their cut. Ignoring that it shouldn't work this way in the first place, the problem is that these days the people getting fat off the system don't at least find people or companies that will give them their cut while still actually knowing how to do the work they contracted for.
**All my opinion, of course.
