For any organization of non-trivial size and operations, they will have problems, and these problems will feel disproportionately painful even when everything else is going fine.
It's not like a school assignment where getting 95% right and 5% wrong will give you a happy A. In real life, those 5% of problems are the thorn in one's eyes that give disproportional pain. Getting 100% right will make you feel nothing because 100% is the passing bar, while getting 95% right will make you feel extra terrible.
Actually, most things in real life simply can't be graded on a 100% scale, because there's always trade off. Thus arguably, some problems will inherently exist because they are the inevitable sacrifice for trade-offs.
Everyone is able to point out what's wrong, at least what feels wrong. After all, our genetics are optimized to quickly spot discomforts.
Some would try to provide solutions, but few could provide practical and effective solutions. Many will propose solutions that grammatically make sense but are factually nonsense.
For the few that get the solution right, it's another funnel of filtering for someone to come up with a correct step-by-step plan to execute it.
It's miraculously rare to all at once propose the right solution, decide on it, plan the execution right, and finally execute it. Execution is hard. Not only is it a question of skill, but more importantly a question of qualities: determination, perseverance, and consistency.
Long story short, talking is cheap, decision is gold, and execution is diamond. Because consistency is diamond.
