We had a guy we hired as part of an IBM software purchase. (Even the tech consultants said this was the most complex implantation they had ever seen and that NONE of the previous installs had actually worked properly -- that boded well for the future.)
Knew a guy -- he was nice but clueless. After a few months they added him to the on-call rotation. Monday morning, big uproar. Off call people had to babysit and restart the customer facing app multiple times. Where was the on-call guy? After a while he came in and his manager wanted to know "What happened?" Yeah, the on-call alert kept going off over the weekend. And it just kept going off so I turned it off.
The next day he was fired. And not that everyone's the same, but to join the parent: we also had a woman from that same company. She could run rings around any of us. True, it was her area of expertise and it wasn't ours, but you could ask any question about any part and she would have a good understandable answer with pointers. had they hired about 19 more of her they might have actually gotten it all to work.
"If something goes wrong IBM will darken the sky with consultants to get you going again." I think that was their selling line that we bought. Lets just say that when all was said and done, every physical and logical device was covered with political dark, sticky, smelly stuff that had fallen from that sky. I don't think that's quite what our CEO was looking for. The tech support guys kept it operating by sheer force of effort and dedication. Once every two week it would have a disaster -- the IBM DB2 databases they used for LDAP wouldn't start, or work, or would kill itself and they're have to restore, sometimes even from tape. And I really don't know why.
It didn't directly affect me -- I was next door in a nearby silo, but weekly went to my boss, shook his shoulders and said "Don't get us within a MILE of anything they're doing. I like the people but they're building a career 100% busywork black-hole." And then no reason, but 2 years later they're shutting our entire side of the company down. Even if they were planning on shutting us down some day, I *DO* think that was a little part of sooner rather than later.
