2.2 The Three Pillars in Scrum
Scrum is all about handling a changing world in an effective way. In Scrum, decisions are made based on observation and experimentation rather than on detailed upfront planning.
Scrum uses an empirical approach in order to adapt to the changing requirements of the customer. Empirical approach is to work in a way that is based on facts, experiences, and evidence. In particular, progress is based on observations of real events, not on plans based on large amount of upfront requirements.
The three pillars of scrum that uphold the empirical approach in controlling the process are: Transparency, Inspection, and Adaptation
