You could sit and think over each option, hoping for divine inspiration – but you may end up more confused than when you started. Or you could leave it to fate – draw straws or pick a number. But, of course, this won't win you the Decision Maker of the Year award!

And how can you be more objective?

To address this problem, Thomas Saaty created the Analytic Hierarchy Process (AHP) in the 1970s. This system is useful because it combines two approaches ...
