'Management by Imagination' by Roger Martin on Harvard Business Review
The perception that good management is closely linked to good measurement runs deep. How often do you hear these old saws repeated: "If you can't measure it, it doesn't count"; "If you can't measure it, you can't manage it"; "If you can't measure it, it won't happen"? We like these sayings because they're comforting. The act of measurement provides security; if we know enough about something to measure it we almost certainly have some control over it.
But however comforting it can be to stick with what we can measure, we run the risk of expunging something really important. What's more, we won't see what we're missing because we don't know what it is that we don't know. By sticking simply to what we can measure, we come to imagine a small and constrained world in which we are prisoners of a "reality" that is in fact an edifice we've unknowingly constructed around ourselves.
The late 19th and early 20th century American pragmatist philosopher Charles Sanders Peirce was the first to point out that no new idea in the world was ever produced by inductive or deductive logic. Analyzing the past, crunching the existing numbers to produce the future can do nothing more than extrapolate the future from the past. So if you stick to measuring what you can already measure, you cannot create a future that is different than the past.
