I've seen this more than once. Senior management thinks maintaining a portfolio of software applications is like flipping hamburgers: they see no problem or risks in one team of developers handing the spatula to another team. What, wasn't the one-day knowledge transfer session not enough? So, the transfer from the home-grown team to Accenture is screwed up. Let's try it again, from the Accenture team to another team; lightning cannot strike twice, can it?

Yep. Worked for a company that was brought in to fix what Accenture messed up. Sadly they were able to regain the contract that I worked on because of some bizarre run around involving another contract.....

There’s a couple of us that were on the Accenture frontend team of the Hertz project that, justifiably, became amazing friends after such a dumpster fire of a project.

Accenture was just as culpable as Hertz in terms of incompetence and negligence.

Oh no, definitely calling out ACN, where I worked at the time. Sorry if that wasn't clear.

Both are bad. Every big "consulting" company sucks nowadays.
