> When writing a technical document, stick to one word per concept Yes, this is absolutely critical. As a tech reviewer I once came across a doc that used no fewer than seven different terms for the same underlying thing. Part of the problem was that it has been written by at least two authors over a couple of months. At least one of the authors admitted that they hadn't take the time to remind themselves what had already been written. In non-fiction, it can be good to introduce variety, and challenge the reader But as a tech author, if the reader has to work to keep track of things through a doc, simply because you have been lazy to check for consistency, you have failed. [Edit] There are a couple of things that can help avoid the problem. The most important is to have a final step that involves consistency checking. Where I used to work, we encouraged a peer-review step before docs where submitted for formal tech review. This significantly reduced the workload on the formal reviewers.
