The Glaze Heuristic

Wish I could take credit for this one but I found it when reading this blog post from Dan North ( which in itself is worth reading ).

As an aside, this raises some interesting questions. What if you are writing scenarios in a domain that no-one seems to care about? (You can tell by watching their eyes glaze when you talk about it.) A lot of what we traditionally call non-functional requirements can fall into this category. For instance, most non-technical people aren’t interested in networking terms like latency, throughput or packet loss, but they might perk up when you start talk about sluggish response times or requests going missing. You can use the glaze test as a heuristic to know if you are talking to the wrong person – or using the wrong language

Looking forward to using this one at the next meeting...
