“
In preparing for battle I have always found that plans are useless, but planning is indispensable” is a well known quote from General Eisenhower. While I would not propose managing a project is the same as ridding the world of tyranny, his sentiment strongly suggests that we should pay careful attention to planning. If a project manager is to be successful, he or she should take great care in planning. Eisenhower didn’t mention the use of any single planning approach like the
PERT Estimate, or
Simpson’s Rule, but surely a planning methodology is necessary to build a project schedule.
Wrong.
Observations
- None of the projects reported a formality (e.g., Global Efficiency Factor, Productivity Adjustment Percentage, PERT Estimate) in scheduling
- Project managers for 64% of the projects had to make all interim milestones fit a final milestone
This, by the way, was the most shocking discovery of my research project… not a single project used a formal estimating approach to define its project schedule. Others have found project management methodologies to be unnecessary for some types of projects (see We Don’t Need No PM Methodology by Pawel Brodzinski).
I tend to use one of two planning approaches. For unfamiliar types of projects, I will work with my technical leads using something like PERT Estimate. For types of projects where I am familiar with the activities to be performed, I just lean on my own judgment (a.k.a. relative comparison). It is quicker.
What about you? How much do you depend on formal methods of project planning?
