Don’t just try to fit into development’s agile process. Create your own lean content development process.
Technical writers are increasingly finding themselves involved in the agile process of the development organization. The most common way this happens is that a writer gets assigned to the team for a sprint and is expected to produce documentation in the same sprint as the developers produce the feature.
This has one huge plus for writers: development cannot declare the sprint complete until the documentation is done. This means that it is in the interest of every developer to help ensure that the tech writer has what they need to get their work done. Given that getting information when needed is a major issue for many tech writers, this can be a very big win.
