It’s rarely the case. You rarely work in vacuum where your work only affects what you do at the moment. There is always a downstream or upstream dependency/requirement that needs to be met that you have to take into account in your development.

You have to avoid the problem that might come later that you are aware of. If it’s not possible, you have to mitigate the impact of the future problems.

It’s not possible to know of all the problems that might/will happen, but with a little work before a project, a lot of issues can be avoided/mitigated.

I wouldn’t want civil engineers thinking like that, because our infrastructure would be a lot worse than it is today.
