Purposedifferent | When effort only needs to be classified roughly, it makes comparability more important than false precision. It helps sort work quickly into manageable sizes. | When effort needs to be thought of as real working time, it offers a simple common denominator for comparison. It sorts work by value, risk, and delivery ability. The result is captured as Ideal Day Estimates, Assumption Notes, and Capacity Caveats. | When a team is starting fresh or working past each other, Team Charter clarifies the shared working basis. It visibly sets out how collaboration, decision paths, and mutual conduct should work day to day. | When collaboration needs more than implicit expectations, it lays out shared ground rules openly. It creates reliability for conduct, availability, and decision paths. |
