> The industry started rejecting Waterfall, early design and system architects, in favor of Agile, just-in-time design and empowering developers. So we saw no need for these visual design tools to model the entire system, since we ended up changing the design during the lifetime of the project anyway. It wasn't also visual design tools that Agile killed. Agile killed design documentation altogether. With Agile, today's problems are addressed on tomorrow's sprint, and changes in software architecture take place only in the code. Any effort to document the system architecture in any remotely rigorous way is quickly deprecated, and teams simply don't waste time maintaining something that might already be deprecated once they finish editing the document.
