Output is easy to measure: tasks completed, features shipped, documents written. Measuring output rewards movement over progress. You can satisfy every item on a [[Building a boring task list]] while having no real impact on the thing that matters. Outcome requires knowing whether the work actually changed anything, which is a harder question and one that often doesn’t get asked until after the work is done and the result disappoints.
[[Hype Doc]] makes this visible over time by recording actual changes rather than activities. [[LNO Framework]] is the task-level version of the same discipline: naming whether a task is leverage, neutral, or overhead before doing it is a way of asking the outcome question before the effort is spent.
