Not just the IT world
Some companies try to shortchange their clients, or even themselves. That's just the way it is.
My late father was in quality control for a coat manufacturer, supplying M&S as their sole client.
The failure rate was about average and QC intercepted those - but the company decided that to save money they would send stuff through that didn't meet the M&S standard and dad had rejected. They really seemed to have believed that no one would notice. Of course it came back. But more to the point - M&S got pissed off with the high reject rate and dumped the contract. Business closed down.
I took a job in the Summer after uni at Great Universal Stores, as a filing clerk. We had to file away, in alphabetic order, little vouchers people had sent in. But these had to go into little plastic envelopes <1cm thick that had been packed.as tightly as possible The company insisted that these were packed so tightly that it was at the limit of physical possibility, to save storage space, and the cost of the envelopes, so the chance of getting a thin slip of paper into the right order was close to zero.And they cut into our fingers as we tried. It was immediately obvious from the state of the files than no one did even try after the first few days. And that also told me that none of us would be there in three months time ( and of course I never intended to be), because the files had strips of relative order, then became random, then ordered again.......
But one day they needed one of these slips. Of course it couldn't be found. I learned from chatting to one of the managers that retrieving these bits of paper was pretty much impossible, so if there was a dispute they just had to surrender. I still don't know which was the worst wast e of money; paying us to (not) file the slips, or making the system unworkable in the first place.
For my part I gave up even going into the files. I took the piss, and waited to be fired. My favourite thing was to grab a clipboard and wander round the building looking busy and concerned.
And when I did get fired it wasn't because of that. No one had even seemed to notice or care. When I went it was a few weeks later as part of the latest mass culling. There were about six of us started when I started and the same about six of us booted out when I was booted out. I assume another bunch were shipped in that afternoon.
