Is there an "official" way that required engineering staffing levels are determined? 6

[Careful34]

Is there a management bible out there somewhere that gives guidelines for how many engineers are required for a particular sized project? For that matter how is project "size" determined? The required completion date must be in there somewhere as well I expect. Is this all from the experience of the Engineering Manager? What if the Engineering Manager is not an engineer and has no engineering experience?

Just curious.

One of the biggest pitfalls I see in project planning and scheduling is this: if I tell a project manager that a particular task will take 8 hours, they would expect me to have it completed the next day. What they don't understand is that in a perfect world when I am not working on anything else that would be the case. The 8 hours is of course actual work time that could be spread over several days, depending on my availability. Its a losing battle.
