Pragmatic DITA on a Budget  

A small documentation team working on a tight budget can now use the tool ecosystem enabled by the DITA standard to create the sophisticated content that previously required long and expensive projects. The author spent just nine person-weeks over three years to replace a custom XML system with a DITA system based on a combination of off-the-shelf software, authoring conventions, and custom scripts.

Agile Documentation with uScrum  

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.
