What do you consider your most useful tool in project management… digital or otherwise? Is it your favourite software… critical paths or pertographs, networks on time perhaps… Microsoft project?

My candidate for the most useful tool is the humble post-it note. After the pencil (with an eraser attached) the post-it has been one of my fundamentals for getting to grips with a new project. It is clear, flexible and allows me to be creative and explain processes to clients.  Give me coloured post it notes and a blank wall and I’m in hog-heaven. So… what is your candidate?
