Objective: Project Initiating
SubObjective: Develop Preliminary Project Scope Statement

Single Answer Multiple Choice

Which type of cost estimate would MOST likely be used early in the Develop Preliminary Project Scope Statement process?

A. budget
B. detailed
C. definitive
D. order of magnitude

Answer:
D. order of magnitude

Tutorial:
An order of magnitude cost estimate would most likely be used early in the Develop Preliminary Project Scope Statement process. An order of magnitude estimate is an approximation that is made without detailed data. An order of magnitude estimate has an accuracy of -25% and 75%. An order of magnitude estimate would most likely be used to create a ballpark estimate because it is the easiest to create.

A budget estimate would not likely be used early in the Develop Preliminary Project Scope Statement process because it would require more detail to create. A budget estimate has an accuracy of between -10% and 25%.

A detailed estimate would not likely be used early in the Develop Preliminary Project Scope Statement process because it would require more detail to create than would be available. A detailed estimate is created from well-defined specifications. A detailed estimate, also referred to as a definitive estimate, is typically created using a bottom-up estimating technique.
