Abstract:

uScrum (uncertainty Scrum) is an agile process developed by a small team at Altitude Software to manage the process of writing user documentation. uScrum manages uncertainty and the unknown, allowing writers to quickly react to changing conditions. uScrum uses orders of ignorance to understand the difficulty of tasks, allowing the team to effectively prioritize regular work together with difficult creative work.
