PMI PMP Project Manager Certification

Answer: e - The standard range for a Rough Order of Magnitude Estimate is from -50% to 100%. (Editor’s note: I recall this question appearing on the PMI exam.)

Key Takeaway: While that range sounds wide, it is actually very easy to miss in the early stage. A good project manager does in-depth analysis before issuing Rough Order of Magnitude estimates. Note that this guideline suggests (wisely) that you’re better off missing on the high side than the low side.
