The empirical process control theory ASSERTS that knowledge comes from experience and making decisions based on what is known IE at defined points within an overall control process, teams must inspect what has happened and, from that experience, adapt the process to what will happen.

The Scrum framework is founded on empirical process control theory so the included ‘Transparency, Inspect and Adapt’ processes are indispensable.

• Transparency

Scrum relies on transparency. Decisions to optimize value and control risk are made based on the perceived state of the artifacts. If the transparency of artifacts is incomplete, these decisions can be flawed, the value may diminish and risk may increase.

• Inspection 

Scrum users must frequently inspect Scrum artifacts and progress toward a Sprint Goal to detect undesirable VARIANCES. Their inspection should not be so frequent that inspection gets in the way of the work. 

• Adaptation 

If an inspector determines that one or more aspects of a process deviate outside acceptable limits and that the resulting product will be unacceptable, the process or the material being processed must be adjusted. An adjustment must be made as SOON as possible to minimize further deviation. 

Transparency and Inspection are important in the Daily Scrums and Sprint Reviews.  Although Adaptation is mainly considered during the Sprint Retrospective, it should be considered at any time during the Sprint if the current process is significantly detrimental to the best value being ACHIEVED.
