You don't have to play with Personas for long before you realise that it is a user experience tool and not just a user interface tool. What do I mean by that? It is straightforward to take a SAPgui transaction and simplify it by removing fields you don't need, merging tabs, etc. and to make it prettier by adding background images, changing colours, and so on. To do that to individual transactions in isolation, though, completely misses the point in my mind. To flip between simplified and standard transactions is jarring and provides a disjoint user experience. Personas is at its best when a user encounters only Personas-enhanced transactions. When they stay within a "Personas bubble".
It seems to me this has lots of implications for a Personas project. You will likely end up simplifying/prettifying more transactions that you expected, even transactions that aren't already complex, because you need to build matching sets. You will also have to choose your users carefully. Users that have access to just a small set of SAP transactions will be much easier to accommodate than users that have access to lots of transactions.
What do other people think? Does it make sense to simplify just a small number of transactions and so have users switching between Personas and non-Personas UX, or do you really need to think on a larger scale and keep users in a Personas bubble?
