A product owner or development team will often be asked for an estimate or a forecast for a product, a feature, an iteration, or a story. But when you go to a team member and ask them it is not uncommon for the color to drain from their face, twitching to start, and their pulse to race. Past experience says that the next words they speak will haunt them for the foreseeable future, maybe even for the rest of their career. It is only a rough estimate you say to reassure them, but they just know you have other plans and the fate of mankind lies in the balance. Or so it seems.
