And what in your opinion is the difference between "systematic approximations and best-guessig" and "knowing when shortcuts are good enough"? For me engineering is using proven and tested solutions every time, even if the solution is not sexy, and art is just "swinging it" - just like using js for everything when they are better more mature solutions.

Since you're not building the same thing every time, you don't have wholesale proven and tested solutions for everything. The engineering part is going about filling the gaps systematically, and figuring out what parts require closer inspection in the first place.

In my opinion, this last part is the art, figuring out what to do when you tread a new path. A good engineer will find the critical parts, but that relies on as much intuition as process. A really good engineer will find the meta-mistakes in the process.

The decision to "swing it" can be an engineering decision. If I am doing something I did before, and all the parts fit, I can swing it, and forego a tedious process. I have to balance the risk of implementation delays and bugs vs. spending time on simulation and paperwork.

It's also perfectly possible to do everything by the book and still fail, if the process is a bad fit, or you run out of time because you're all caught up in following procedure instead of taking common sense shortcuts.

So either swinging it or doing it by the book can be engineering or idiocy, depending entirely on the situation, and, in retrospect, the outcome.
