Method: Work by analogy. Among existing software products the author found one with the interface almost ideally fitting to the future needs of DFA packages.
Results: Shocking (but only at first): the software product with the “ideal” DFA interface is neither analytical nor calculational package, but a game, a computer simulation game. Indeed, computing gaming industry is the most creative and innovative niche of software development, where computer-human interfaces are given the highest priority. It is only logical to look there for the ideas for the best interface, especially for such interactively challenged products as DFA models.
Conclusions: If the author is correct in predicting the communicative requirements of the future DFA models, then DFA developers should look closely at some computer games and borrow ideas for interface design.
Keywords: Actuarial software design.
