Employability is analysed for the specific case of engineering education. A conceptual model is developed of the processes of transition, using a system-engineering method. This model embodies a proposed causality whereby identified factors result in successful outcome, i.e. meaningful employment with a good fit. The theory suggests that the employer’s tacit expectations are important in evaluating candidates. It is shown that graduates can anticipate these organisational expectations, consider the implications for personal fit, and write better job-applications for those jobs where they deem the match to be good. Other implications for graduates and their mentors are identified. The model also provides a framework for further research.
