It continue to amaze me how willingly people offer their advice on software architecture. Most people would struggle to understand the inner-workings of email, but that doesn’t seem to stop them. And if they do have some experience with the topic – regardless of how long ago – some people think they are experts.
I’d never give advice on corporate accounting; nor how to manage your finances or investments – that’d be illegal without the right training and certification (just ask CBA).
By all means ask questions, get your architect to explain their rationale, and hold them accountable. But don’t do their job for them.
