FLEX, on the other hand, holds everything open to question and encourages double-loop learning. Scrum is founded on empirical process control theory, or empiricism. Empiricism asserts that knowledge comes from experience and making decisions based on what is known. Scrum employs an iterative, incremental approach to optimize predictability and control risk.
The Intention of this Article This article will discuss how Scrum and SAFe are based on many unexamined assumptions, the intention of this article is not to dismiss or diminish either. Assumption — a thing that is accepted as true without proof. Presupposition — a thing tacitly assumed beforehand at the beginning of a line of argument or course of action Although these four terms are synonyms, most Agile frameworks and methods are defined on what could best be called presumptions.
The scientific method, paraphrased from Wikipedia, involves: careful observation applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation formulating hypotheses, via induction and deduction, based on such observations The hypotheses are then validated or invalidated by experiments or additional observations. FLEX, on the other hand, holds everything open to question and encourages double-loop learning Scrum Empirical process control is required in complex systems From the Scrum Guide: Scrum is founded on empirical process control theory, or empiricism.
Using Lean thinking helps us achieve flow and create great environments for Agile teams. All Rights Reserved. Then these hypotheses are subject to empirical test.
Since the empirical successes of SR, it is considered 'true' so has been kind of elevated to the status of an accepted theory though, fundamentally, it is a set of hypotheses.

Axioms are assumed to be true without a proof. Some axioms in certain contexts are redundant, meaning they can be proven form the rest of the axioms, for example the axiom of pairing is redundant over the rest of ZF set theory. That doesn't mean the axiom of pairing isn't an axiom.
Axioms are assumed to be true without proof, not always unprovable. In fact, one of the inference rules you're allowed to use during a proof is to just restate the axioms. This is in a round about way, a proof of the axiom itself. Obviously this isn't a convincing proof because it starts with the assumption that A is true and ends with A being true, but it's still in the technical sense of the word a 'proof'. So it's not that axioms cannot be proved, it's that they're trivial to prove since we already assume them to be true.
Sometimes other axioms we assume are strong enough to prove them on their own, which leads to redundancies.
