“You’ve got to get down to the working surface, and build your estimates on actual facts, history and judgment. Otherwise, your plan is going to have big holes in it.”
Totally right on the substance. Excellent project management . . . so far. Project estimates must arise from actual facts and relevant experience – to the extent possible.
Whose facts? What experience? This is where the speaker’s narrative took a turn that seriously undercut the value of his advice. He described the many hours he had spent in researching and preparing estimates for one project.
He applied his own personal experience? He invested his own time to produce detailed estimates?
The context was that of a complex, good-sized challenge with a number of team members and stakeholders.
