“All conventional wisdom has an element of truth to it, but good design...” — Henry Petroski Quote

All conventional wisdom has an element of truth to it, but good design requires more than an element of truth - it requires an ensemble of correct assumptions and valid calculations.

You can almost say that a design error is a human error because, after all, it's we humans who do the designing.

Companies selling a product play down its vulnerability and emphasize its robustness. But only after technology leaves the dock is it really tested. For human operators in control of a supposedly infallible system, complacency and overconfidence can take over, and caution may be thrown to the wind.

Failure is central to engineering. Every single calculation that an engineer makes is a failure calculation. Successful engineering is all about understanding how things break or fail.

When you try to redecorate or design your home yourself, nothing is really wrong, because it's your touch. You're going to live there. You should be happy with it.

Many are ready, when listening to the inventor, to belittle and deny his achievements so that he will no longer be heard in honourable places, but after some months or a year, they use the inventor's words in speech or writing or design.

Many people think that being a graphic designer means going to an expensive art school and buying expensive software that will cost you thousands of dollars. This is so far from the truth. There are hundreds of online education centers that offer top-notch graphic design training.

The sky is a free asset in design, and nothing unnecessary should be planted that takes away the sky.
