Sounds like work (where I worked for 30 years before retiring).
The (right) engineers spend a lot of time developing a new piece of equipment or process, test it out, go back and work out the bugs, test it out again, work out some more bugs and finally decide it's ready for installation/use.
It's bought/built/installed and put into service. The darn thing works, just like they said it was (remember, that takes the right engineers, not just any or all or every engineer, the right engineers).
Then, after it's proven to work as advertised the process/production engineers along with maintenance decide they can "make it better."
That is followed by more money spent to change a well working piece of equipment/process-to make it better, of course.
At some point, things begin to fall apart, the process/equipment won't run, finger pointing, meetings, shouting matches ensue and after a few weeks/months of this management calls in the original (good) engineers who show up, look at the mess their design has become with great alarm and lots of questions. Which results in more finger pointing, meetings and shouting matches.
The equipment is "restored" to it's original form/function and runs like a top once again. Just as advertised.
Then, of course, the same cast of characters begins to "improve" on it and the cycle repeats.
I got to watch that from a distance many times over the years. Fortunately, for me, no one saw the value of my area and no one wanted to spend money to make it better and I was seldom bothered by any outside engineers, good or bad. The "good" ones would come from overseas, look things over, marvel at the way things ran, the quantity and quality of what we made and even ask if we could make product for overseas plants (which we could not due to the before mentioned lack of money spend to improve/expand our area/equipment over the years.)
It's fun, from a distance. When you're in the middle of it, it's a PITA. Big time.
I wonder if the CZ design engineers read internet forums and what they think about complaints (when their pistols work just like they were designed) or suggestions for improvement.
