I wonder why nobody mentioned it - there is one more advanced principle AHA: (Avoid Hasty Abstractions) https://kentcdodds.com/blog/aha-programming#aha- Overusing the DRY principle can make software almost unsupportable.
Yes, IT processes significantly differ from those in other areas and can't be evaluated by the same methods - due to the complexities, hidden problems, and overevaluated expectations. For example, the known fact: adding a new member to a team doesn't linearly increase productivity.Nowadays probably AI will help here :)
There is also more advanced AHA principle (https://en.wikipedia.org/wiki/Don't_repeat_yourself in alternative section) - which is an evolution of DRY and is great for avoiding redundant complexity caused by DRY.
