An associate of mine sent me an e-mail with a link to an article that purported to overturn project management myths, but I had never heard of any of them.
One of these myths being overturned was that project managers are only concerned with scope, schedule and cost, and routinely ignore other parts of their projects, like stakeholders or resources. I must have read or heard hundreds of papers and classes on project management, and I've never, ever heard anything like this, but I suppose the article's authors felt such a perception was so widespread that they needed to spend a few hundred words correcting this wrong-headedness.
I don't want to be left behind if this is where the management world is headed, so I'll do some my debunking myself. The commonly held perception that all accountants are weasels is provable false. I am familiar with many accountants, and I know for a fact that at least some of them have a minimum of one human parent.
Another myth? The idea that risk managers are attempting to seize control of the project management world by baffling their opponents with statistical jargon until they give in for fear of looking ignorant simply can't be 100 percent true, as risk managers themselves would have to agree.
The short answer here is that making a point about project management by overturning myths that nobody holds to involves a certain amount of making assumptions about readers' presumptions, and that is an unsatisfactory approach.
Full disclosure: I once presented a paper entitled The Bottoms-Up Myth, where I argued against the practice of re-estimating the remaining work in a project, adding that figure to the cumulative actual costs, and declaring the result to be a better estimate at completion than the calculated version. I felt confident in describing such a practice as a myth, since almost everybody I've ever met in the estimating world seems to think that it's just great to do things that way, even when it's provably loopy. I'm interested in seeing what all of you think.
