A plan is not a document. A plan is a set of ideas that may be represented by a document or by other kinds of artifacts. In Rapid Testing, we emphasize preparing your mind, your skills, and your tools, and sharpening them all as you go. We don’t reject planning, but we de-emphasize it in favour of preparation. We also recommend that you keep the artifacts that represent your plans as concise and as flexible as they can reasonably be.
The world of technology is complex and constantly changing. If you’re prepared, you have a much better chance of adapting and reacting appropriately to a situation when the plans have gone awry. But all the planning in the world can’t help you if you’re not prepared.
