Surely getting into specifics allows you to demonstrate the real-world applicability of agile? (Or otherwise..)
Not being rude, but if people don't want to talk about specifics, how do you demonstrate the worth of agile at all?
"Agile is great and works really well for us, just don't ask me to talk about anything specific." OK!
Agile isn't a specific methodology though, so there sre no specifics to discuss.
Agile is. aset of well founded principles. Agile means an empirical process , if something isn't working then you adapt. If you don't adapt and keep finding your process is not working then you are not doing Agile so then you can't complain.
