In a first pass calculation for quantitative analysis of risks, in which we are looking to estimate the total damage impact to the project that would be possible if a risk turned into an actual problem, we sometimes start with a ROM, or rough order of magnitude level of calculation precision. Mathematically, what is meant by a rough order of magnitude estimate of accuracy?

Select one:

a.

numerical verification of the source of the estimate is necessary

b.

a very high degree of precision is required for this estimate

c.

the power of ten that would apply to the size of the estimate number, such as hundreds, thousands, millions, etc.

d.

an estimate that is such a high number, its impossible to determine
