That "spec freeze" idea from amy is spot on. It's about setting a clear line, which we need in a lot of places. Like when my friend kept changing our weekend plans last minute, I had to say "final answer by Thursday or I'm making other plans." It worked. @jennifercooper, I get that some back-and-forth is normal, but constant rework isn't a process, it's a drain. The engineer needs to do their homework first, not use your drafted work as their scratch pad. A signed agreement makes the cost of their changes clear to everyone.
