Assumptions vs. Facts

Dr. Lewis Ireland wrote the excellent article below in 2003 talking about the differences between Assumptions and Facts.


The difference between an assumption and a fact is often subtle and confusing. Some organizations, and individuals, view assumptions and facts in the same light. This approach causes confusion in managing both the assumptions and facts as well as communicating accurately the situation during planning and execution of projects.

The American Heritage Dictionary defines both words in the context of planning as:

• Assumption – a statement accepted or supposed as true without proof or demonstration.

• Fact – something presented as objectively real or something that has been objectively verified.

Planning a project using the wrong term can convey a different meaning to fact or assumption with catastrophic results. Facts do not change whereas assumptions are typically about a future state that may or may not come true. Listing both facts and assumptions as assumptions can also cause confusion because the project manager does not know which assumptions to track to ensure they are converted to facts.
