..things always have a way of taking longer...
A generalization with no basis in fact.
In IT I go into a large shop. A job that must run daily takes over 60 hours to run. They blame DB2. They implement some of my suggestions and it runs in 3 minutes. It they had implemented all of my suggestions it would run closer to 3 seconds.
In another shop my suggestions reduce 1 12 month project to 3 months...and that is only because I made the suggestios in month 2.
Repeadtedly things take longer due to poor design, poor understanding of the situation.
As a consultant I see that many HR and management have the goal of perpetual employment by not solving the problem. Solving the problem would make them jobless.
That's the biggest subconscious motivation for 80% of employees, and causes 80% of trouble in the world. That's the real reason for open borders: to keep the teacher's union and the government gainfully employed, as well as their retirement Ponzi schemes from collapsing. It's also why western governments support funding the Ukraine war forever, without any achievable goal posts.
