The Profession of an Engineer

Engineers use their knowledge of science, mathematics, and appropriate experience to find suitable solutions to a problem. Engineering is considered a branch of applied mathematics and science. Creating an appropriate mathematical model of a problem allows them to analyze it and to test potential solutions.

More than ever, Engineers are now required to have knowledge of relevant sciences for their design projects, as a result, they keep on learning new material throughout their career.

If multiple options exist, engineers weigh different design choices on their merits and choose the solution that best matches the requirements. The crucial and unique task of the engineer is to identify, understand, and interpret the constraints on a design in order to produce a successful result. Constraints may include available resources, physical, imaginative or technical limitations, flexibility for future modifications and additions, and other factors, such as requirements for cost, safety, marketability, productibility, and serviceability.

Engineers typically attempt to predict how well their designs will perform prior to full-scale production. They use, among other things: prototypes, scale models, simulations, destructive tests, nondestructive tests, and stress tests. Testing ensures that products will perform as expected.

Engineers usually include a factor of safety in their designs to reduce the risk of unexpected failure. The study of failed products is known as forensic engineering, and can help the product designer in evaluating his or her design in the light of real conditions. The discipline is of greatest value after disasters, such as bridge collapses, when careful analysis is needed to establish the cause or causes of the failure.

Engineering is a well respected profession. For example, in Canada it ranks as one of the public's most trusted professions. In science fiction engineers are often portrayed as highly knowledgeable and respectable individuals who understand the overwhelming future technologies often portrayed in the genre. The Star Trek characters Montgomery Scott, Geordi La Forge, Miles O'Brien, B'Elanna Torres, and Charles Tucker III are famous examples.

Occasionally, engineers may be recognized by the "Iron Ring" – a stainless steel or iron ring worn on the little finger of the dominant hand. This tradition began in 1925 in Canada for the Ritual of the Calling of an Engineer as a symbol of pride and obligation for the engineering profession. Some years later in 1972 this practice was adopted by several colleges in the United States. Members of the US Order of the Engineer accept this ring as a pledge to uphold the proud history of engineering.

A Professional Engineer's name may be followed by the post-nominal letters PE or P.Eng in North America. In much of Europe a professional engineer is denoted by the letters IR, while in the UK and much of the Commonwealth the term Chartered Engineer applies and is denoted by the letters CEng.
