exchange format for models. That said, it is not yet clear what other tools are currently available that support ArchiMate. The ArchiMate standard aims to provide an architectural modelling technique that complements rather than overlaps standards such as UML and BPMN, so prior use of UML/BPMN does not have to be reworked, and these notations can be used in parallel with ArchiMate. Indeed BiZZdesign Architect allows links to external UML/BPMN models, although, unless BiZZdesign tools are also used for these models, these ‘links’ are just a matter of a textual reference, which raises again the issue (mentioned above) of non-integrated models and the potential for inconsistency. Ultimately, we decided on the following approach to tool use: once we had reached the stage where a more sophisticated tool was required, we selected a key area within the domain and modelled it using BiZZdesign Architect, initially at a high level and from an ‘as is’ point of view. We carried out this plan once we had finished the business process modelling and the e-Framework’s SUM development (at the end of November); specifically, we modelled the business areas around research grant management using ArchiMate.
8. Evaluating TOGAF Our initial assumptions about TOGAF were that it would be a sort of ‘methodology’ that we could follow to produce our EA, however this turned out not to be the case. In fact, on first examining TOGAF (before the training) our impression was that on the one hand, it is very large and quite daunting, but on the other hand it is very non- prescriptive and flexible, and much of it is optional. It was difficult to see how best to select from or
