Europe may sound like (and be intended to sound like) a single place. But, of course, it is not. It is a grouping of mature democracies with laws, institutions, and practices, developed over many centuries. Each and every country in Europe is different (profoundly different), and what may be appropriate in one could turn out to be disastrous in another. But although these differences do exist, there are certain elements which are common throughout and which must be understood by anyone wishing to practise engineering in any of the main European countries.
