if you botch even one of these, word spreads very quickly.

Not really, unless you have a large exposure.
Case in point (that was never spread online or otherwise):
This pic shows how a botched IMS Retrofit procedure
killed an entire engine, without even harming the IMSB!
The owner of the car had a local shop carry out an IMSR. They were a prominent shop on the east coast that had about 60 retrofits under their belts. The job was carried out and all was well for about 100 miles. The owner was then driving down the road and heard a loud bang all of a sudden, then the engine died. He tried to restart it and the engine only had 3 cylinders.
A timing chain was found hanging out of the cam cover, and he knew what that meant. He called me up, asked what it would cost to fix, then after I gave him our timing chain replacement/ failure cost breakdown he asked if I wanted to buy the car. He sent pics and I bought it... Then hit fast forward.
The car arrived and the chain was hanging out of the cam cover, for sure. I had one of my guys pull the engine and I decided to take it apart to document what happened to cause the failure. Chains do break, but its generally not this radical, so I was interested to see what the root was.
What you see here is the result of someone who didn't have the correct mindset during the procedure. They didn't realize that there's two different lengths of bell house bolt and they installed a long bolt in a shallow hole. They were in a rush and decided to use an impact wrench, so they just hammered it in, and didn't realize that the longer bolt blew a hole right through the crankcase and directly into the timing chain well!!!!!!
So, the chunk of aluminum that blew out of the case was picked up in 100 miles by the timing chain, where it effectively was fed between the exhaust cam sprocket and the chain, thus stretching the chain to a point of failure and creating an at speed failure of massive proportions with every part of the engine impacted/ wasted in some way. When the chain snapped so quickly, it wrapped around the spinning exhaust cam and blew the hole through the cam cover.
So, there ya have it.
People working against the clock create issues all the time as its incentive to rush and do a quicker job, rather than a better job.
You won't find a clock in any work area here. In fact the only clock in the entire facility is in the customer waiting area. When I travel to instruct classes I'll usually pop in one some well known shops in the area that I am in, especially if they buy a lot of products. There's been a few times that after I showed up somewhere that I was shocked at how loosely the processes were being carried out. By the same taken a few places blew me away with their attention to detail. That number is like 5 across all of North America, and they were generally the lesser known shops.
You can rush failure, but its impossible to rush success.
