Lucas F. Costa:

In this blog post, I’ll elucidate why backlogs exist and why they never shrink. Then, I’ll expound on why they’re useless and harmful. Finally, I’ll demonstrate how one can work without a backlog and explain why it’s much more productive to do so.

I agree whole heartedly with his “why they never shrink” logic, but I’m not willing to say that makes them “useless and harmful.” I’m not sure Lucas even believes that, since his advice of what to do instead at the end of the post boils down to “keep a short backlog.”

Still, I enjoy Lucas’s thought process and you might too. Recommended reading.
