In Production

So, as the students were coming back to school today, another teacher passed me in the hall and said, "So, I hear you're in production, congratulations!"

Like farmland?

I'd never heard that before, but I suppose it might be about the most accurate description of my current state. This is sort of like farming -- high inputs, a yield that won't be determined for some time to come -- so, "in production" I am.
