Most frameworks (web-frameworks at least) get you from 0 to 80% in very little time. Nice layout/css etc, but they require you to learn how they want to do everything; which can be both cumbersome and time consuming. Frameworks also gives management false expectations of how long it takes to make something. "It looks like you're 80% done with the web-page already, and we've just started - great!" — Management
"But we'd like a quick chat to understand why the last 20% took so long" — Also Management
Over time I’ve learned that the correct response is, approximately, “Sorry, I’m in the middle of [important work], please book 30 minutes for us and [stakeholders] to discuss it.” Gives me time to prepare so that I’m not caught off guard. And to bring backup if I think I need it.
