Art or Science?

PM Certification commentary by William Duncan, IPMA-USA Certification Director.
Once again, from a LinkedIn discussion … someone posted a question. “Is project management an art or a science?” There were nearly 30 comments, most of which argued “both,” and most of which leapt right into the discussion without bothering to define their terms. So here is my post:

As is my wont, I checked the dictionary …
There are two definitions of science: the study of the natural world, and an organized body of knowledge. Project management does NOT meet the first definition; it does satisfy the second. So we can say PM is a science, but not according to the most common definition.

As well, there are two definitions of art: producing works to be appreciated primarily for their beauty or emotional power, and skill at doing something. Project management does not meet either definition, although GOOD project management would satisfy the second. So again, we can say that PM is an art, but not according to the most common definition.

More to the point … what difference would knowing the answer make to you when managing a project? I suspect the answer is “none.”

On the other hand (and my biases are showing here) … would you rather hire a project manager who has proven their knowledge of the science of project management, or one who has demonstrated their grasp of the art? Would you rather hire a project manager who has passed a multiple choice exam? Or one whose performance has actually been assessed against a set of defined criteria?
