Conversations with Dave

You raise another interesting issue. My experience is that few (in fact I can't remember any) systems are designed and developed to be replaced. There are generally some conversations about modules, building blocks, and plug-ins, but I don't really know whether the conversations ever go further than that. Perhaps the conversations can't.

Hence, the long life of certain systems.

In statistics, as I recall, one can perform sensitivity analysis. I haven't heard any discussion like this regarding systems.

What insight do you have to this issue?
