No, it's not a typo. A plog is short for 'project log' like a blog is short for 'weblog' or 'web log.' And plogs start to be used as tools to manage projects, especially in the IT world, as discovered Michael Schrage of the MIT. He reports his findings in an article published by CIO Magazine, “The Virtues of Chitchat.” Schrage found that if plogs are not really commonplace, they're not exactly rare. And they are even used to manage large IT projects, such ERP rollouts.
I totally agree with him that a plog is of great value to integrate people in a team or to keep track of the advancement of a project. And you, what's your view? If you're a project manager, do you use a plog for better control? And if not today, will you use one in the future?
