Is Agile a Value System or Belief System?

Yesterday, I had a realization; a bar is a good place to engage in philosophical discussions with friends. To add spice to it is Google. We, few friends, were arguing - "Is Agile a Value System or Belief System". Keeping the sprint of engineering alive we agreed to settle on a definition of value system, belief system, value, and belief.

Value System:  A coherent set of values adopted and/or evolved by a person, organization, or society as a standard to guide its behavior in preferences in all situations. - http://www.businessdictionary.com/definition/value-system.html

Value system:  the system of established values, norms, or goals existing in a society - https://www.merriam-webster.com/dictionary/value%20system

Value: One's judgment of what is important in life, a person's standard behavior or principles

Belief and Belief system: A belief is something in which you believe without supporting facts. A collection of such belief around a context is a belief system.

In some cases, values and value system are backed by verifiable facts or folk lore, myths and legends (not verifiable because concerning events happened in distant past so blurry stories are embedded in society's collective memory or facts and belief manufactured to further an agenda purposefully or unknowingly).

For example believing in the (or many or none) God and associated factors is a belief system but accepting that we do not have any proof of existence or non-existence of God is a fact.

Now, is Agile a belief system or value system?

Certainly, Agile is not a belief system also not a value system but it promotes a value system. The real question is - are values promoted by Agile based on facts (empirical evidence) or manufactured facts and beliefs?

We need more many visits to the bar to explore further :-).
