Since the introduction of computers to support design and analysis, concern often has been expressed that the use of software tends to result in a decline in basic structural engineering skills. The modern use of computer programs to carry out design processes introduces an element of risk. The risk must be assessed and managed. The use of computers has many benefits but demands a higher level of intellectual effort and competence than in the past. The paper explains why this is so and discusses how process control strategies can help to ensure that computer-aided design not only provides an acceptable level of risk but can also have potential to increase competence.
