A chain saw will not tell you which trees to cut or what protective gear to wear. To use one safely, you must plan your cuts, use protective gear, and take appropriate safety precautions.
Anyone who has seen a chain saw in action knows this.
A CMS (Content Management System) will not tell you how to organize your content or understand your processes. To use one safely, you must organize your content, understand your processes, and understand the problem(s) you want the CMS to solve.
Anyone in technical communication should know this.
The only difference is that most people know that chain saws are dangerous and plan accordingly.
