I'm retired from IT after 30 plus years and this frankly has to be one of the worst software upgrades and migrations that I've seen. But I I'll be good and keep biting my tongue so I don't say what I've really wanted to say for the past couple of weeks.
The worst migration I have ever been a part of in my lifetime was the change in Texas when the Electricity market was de-regulated in 2002, (except for those served by a company owned by a municipality or a utility cooperative.) If Texas were an independent nation, its electricity market would be the 11th largest in the world.
All orders for residential and commercial electric service, start service, and stop service, for about 85% of the state now went through a clearing house, who was then supposed to notify each local operator of power stations and power lines to start or stop or repair service.
Many hundreds of thousands of orders for stops and order for starts statewide, got delayed for months at the clearing house, due to programming glitches that
somehow had not been foreseen in the pre-lauch "testing". One of the larger electric providers, poo pooed the problems by stating that over 98% of all service orders had been accomplished. Well, yeah, with 6 million customers statewide, that 2% of orders still mucked up in the "pipeline" was a LOT of customers calling in to sort out their problems. And that was 2% of all orders over many months... as old orders finally got fixed, new orders coming in were being delayed.
I know, because I worked in the telephone frontline customer service for a large electric provider.
Before de-regulation, there might have been 3 or 4 times a day when the call light turned yellow to indicate that there were customers holding. That usually cleared up after 10-15 minutes.
But, after the de-regualtion mess got into full swing, I would log into my phone pad in the morning, and the call light would be red, meaning there were many many customers already on hold. And the call light stayed red all day long, and was red when I logged off each day.
Eventually, after many months, the programmers contracted to come in and fix the mess got it fixed.
But you would have just expected more testing for a $24 Billion electric market. Texas, after all wasn't the first state to de-regulate their electric market...
I say all that, particularly, because before de-regulation the utility company operation was regulated by Govt. And Amtrak, is also Govt. regulated.
