Thank you so much for that Amanda!
Unfortunately, it's still not 100% clear to me how these pertain to me in design? For example, I hear these terms freely at meetups, in interviews, etc., but what's the 'gist'? What's a quick, simple, readers digest definition?
Is agile all about taking a project and breaking it down into smaller chunks? What about putting out a product quickly then iterating based on user feedback, is that technically "lean"?
I understand that I'm taking these words that are specific to software development and manufacturing and trying to understand it my own little UX designer mind so apologies if I am causing everyone major confusion.
