Essential Mathematical Formulas for PMP Certification Test
A = B + C
Example
Imagine you’re planning a construction project, and you’re estimating the number of bricks needed to build a wall. You might not need the exact count; instead, you want a general idea of the quantity. If someone tells you that you’ll need “thousands” of bricks, that gives you an order of magnitude estimation. It suggests the scale of the number without specifying the precise count.
Let’s say you’re planning a software development project, and you’re estimating the time it might take to complete a task. If you think it’ll take “days” or “weeks” rather than pinpointing the exact number of hours, that’s an order of magnitude estimate. It gives an idea of the task’s duration without providing the precise hours or minutes.
Order of magnitude helps in project management by providing a quick understanding of the scale or size of something, allowing for rough estimations without delving into precise details. It’s about grasping the general size or scope of a task or value without needing exact figures.
