There is a great book called Manage It!, by Johanna Rothman. She does not disappoint, and really gets into the nitty gritty details about managing projects. While this is billed as a “project management” effort, it really does apply to product managers a great deal.
What's so cool is that Adam's taken my templates and suggests a modification for product managers: a release plan from the salient bits of the project charter and the project plan.
That's why I published the templates, and said to modify the templates for your own use. I'm thrilled other folks in the organization can find ways to use them.
