I came up with a much longer version of this but here is the skinny:
As a new employee, I was tasked to create an application. I did all my core work on time but the underlying database architecture was not up to the job and causing major delays.
To have something to show, I created a proof of concept using a different database architecture, which worked fine, but management was adamant I use their solution and unhappy the project was slipping.
I created a second demo using the "correct" architecture, which everybody promptly hated because it was very slow and sometimes failed due to a vendor bug.
I was then written up and given six months to "turn things around". To help with the database architecture, the company assigned a team of data engineers to fix the problem. They are still at it four months later while the project languishes. Vendor still hasn't fixed the bug.
I have been working on other things in the meantime and haven't missed any deadlines, but I was told I have two months to "improve", although the definition of improvement is totally nonspecific, consisting of "better collaboration", "better understanding" and "better enthusiasm".
My gut tells me they need to throw somebody under the bus to appease management and a relatively new employee probably fits the bill. I also get the impression that if somebody says you need to improve but can't really say exactly what it is you need to improve, you are probably already done for. Should I bail now while I still have a job or wait and see if maybe this will all blow over?
