Human-Computer Interaction 3e Dix, Finlay, Abowd, Beale
For the scenario proposed above:
Open ended - any notation/drawing is acceptable. It should include all of the actors identified in the answer to 13.1, and the relationships between them, as well as external and internal factors, motivations, and so on. For example, the university is interested in attracting students. It has a number of motivations and issues: raising funds, meeting need for learning provision, demand for resource provision. Students are interested in available locations, quality of learning provision, value for money, closeness to family, and so on. A rich picture can use any notation but should represent the entire system spatially.
A system owned by university management, to be operated by careers staff and students working in careers offices and schools within the context of UCAS regulations and competition from other universities, to sell courses to students, generate income for the university and meet a need for learning provision.
|T||Student intention to go to university transformed into place offered and income for institution. Need for learning provision transformed into need met.|
|W||Increased student numbers will increase income and effectiveness.|
|E||UCAS and university regulations; competitive environment from other institutions.|
