Refactoring for flexibility

A prototype is, well, a prototype. It breaths life into an idea, it takes an interactive form, and this generates new ideas and insights.  Alongside functional ideas and insights (hey! wouldn’t it be cool if the user could do *that*!) – are engineering ideas and insights (hey! wouldn’t it be cool if we could make…
