‘Oh, how I wish I could shut up like a telescope! I think I could, if only I knew how to begin.’ For, you see, so many out-of-the-way things had happened lately, that Alice had begun to think that very few things indeed were really impossible.

– Down the Rabbit-Hole, Alice’s Adventures in Wonderland, Lewis Carroll Problem management is sometimes ignored as being too difficult, if not impossible. It is true that it is not always possible to find or fix the root cause of a problem, but that is not a reason not to try. This book has presented a toolbox full of different tools for tackling problems. Different problems will require different tools in the same way that different DIY challenges require different tools. Hopefully, you have not only increased your own toolbox, but also now have a greater understanding of which tool to use when. Telescopes allow us to see stars and planets in far more detail than we could possibly see with the naked eye, and in the same way, problem management techniques allow us to home in on problems and see their behaviour in a way which is just not consistently possible using ad hoc techniques.
