One of my current projects involves documenting processes for an application that are still under development. As such, much of what I write may change, depending on how processes are changed during the course of development.
At one point, I tested one of the processes so I could determine functionality and document it. In doing so, the process came back with an error message that I wasn’t expecting and didn’t have any user-friendly information, other than a cryptic error code. I contacted one of the developers working on the application and told him what I found. I gave him the error codes I experienced and steps I took to get them. He told me, “you’re coming across bugs that we didn’t even know we had.”
It occurred to me that I was doing more than just documenting the application. I was also acting as a beta tester.
One aspect about writing technical documentation is learning about what you’re writing. In order to write about a process, you need to understand how it works. If you’re documenting an application, the best thing you can do is run the application in a safe environment (such as development or a sandbox), learn how it works, and use it to document steps and capture screens. In doing so, you come across application bugs and even come up with ideas to make the application even better.
I’ve long argued as to the criticality of documentation. It records important information and serves as a reference. However, until this point, it didn’t occur to me that the document development process could have a symbiotic relationship with application development. To me, this adds further fuel to the argument that documentation is critical and required.
