> Sometimes the new guy can make a better version themselves over the weekend, not because they’re a supergenius, but because they’re not hampered by 47 teams all trying to get their stamp on the project.
In 99.9% of cases what seems to be "the better" version is better only for the "new guy" or rather his ego.
Those 47 teams hampering doesn't necessarily mean a bad thing, and more often than not actually well justified "stamps".
You only understand those things when you turn from the "supergenius" into an owner who have to take care not only of numbers on screen, but also security, interfacing, management and so on.
Or you don't turn into.
That is often the case, but far from all the time. Other times something is made so needlessly complicated by office politics that it may never get shipped.
Not saying you're wrong in all cases, but there are enough examples of hugely expensive megaprojects which totslly tanked, which would have definitely been much more successful with OPs approach if executed correctly. Not saying they would be done and done within a weekend, that's silly. But the alternative, poorly defined integration interfaces, multiple contractors, multiple stakeholders with conflicting requirements and zero (real) regard for the user is unfortunately fairly common, both in public (city/regional/government) and private bureaucracies.
The examples are legion, and they always seem to have NIH and baroque requirements, and be rather over- than underspecified. I would go so far as to say that these projects are almost never successful (and definitely never on time and budget).
