Around 2000, when #PuTTY first started to become popular, it brought me more and more email. At some point it became hard to answer it all, and my inbox started to grow.
Young and optimistic, I came up with a plan to fix this. I drew a line in my inbox (by sending myself an email with subject "---------"), and told myself that I'd keep the region below the line clear, and every few days, deal with a few messages from above the line, until eventually the line was at the top again.
Of course, it didn't work at all. Soon enough there was a huge backlog even below the line, and the stuff above the line was all still there. The line became part of the problem, not the solution.
It took a historian friend of mine to point out the fallacy. To answer more mail, you must spend more time answering mail. No amount of classifying, rearranging, or reorganising it makes there be less of it. You must either answer the mail or decide not to. (And once there's too much of it, only one of *those* is possible.)
This is a post about management methods that respond to any problem by spending more rather than less time moving issues around the bug tracker or kanban board or what have you.
