In my 50s and have a lot to learn but I believe this group will be a great source for my education.

Perfection is expensive, but ambiguity is even more expensive. Most teams do not lose time because they aim too high. We lose time because we do not agree on what “done” means, so we keep revisiting the same work. A clear Definition of Done is not bureaucracy, it is a time strategy that protects cycle time, reduces rework, and speeds up decisions. AI amplifies this truth. When we generate faster drafts, the bottleneck becomes alignment. If “done” is unclear, we simply produce more versions, faster. If “done” is clear, we produce better first drafts, faster, and we get time back instead of creating more noise. ------------- The Time Leak We Keep Normalizing ------------- We have all watched a simple deliverable turn into a multi-week loop. Someone submits a document. A reviewer says, “This is not what I expected.” Another reviewer asks for more detail. A stakeholder wants it shorter. Someone else wants it more formal. The author revises, resubmits, and the cycle repeats. We call it collaboration, but often it is a missing agreement. The real issue is that we asked for “a brief,” or “a summary,” or “a plan,” without defining the job the artifact must do. That vagueness creates handoff latency. People cannot evaluate quickly because they do not know what standard they are evaluating against. So they revert to preferences. This is also why meetings expand. When a deliverable is unclear, we schedule a sync to “align.” The meeting becomes a debate over expectations that could have been written in two paragraphs. That meeting leads to changes, which leads to more review, which leads to more time lost. A Definition of Done is how we stop paying this clarity tax. It gives us a shared finish line, which shortens time-to-decision and prevents expensive rework. ------------- Insight 1: “Done” Is a Contract, Not a Feeling ------------- Most teams treat “done” like a vibe. We know it when we see it, and we assume everyone else does too. That assumption is the source of wasted hours.
