What are the 3 pillars of Scrum? - Answers- 1. transparency
2. inspection
3. adaptation.
, Transparency - Answers- Significant aspects of the process must be visible to those
responsible for the outcome.
Transparency requires those aspects be defined by a common standard so observers
share a common understanding of what is being seen.
For example
- A common language referring to the process must be shared by all participants; and,
- Those performing the work and those inspecting the resulting increment must share a
common definition of "Done".
Inspection - Answers- 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.
Inspections are most beneficial when diligently performed by skilled inspectors at the
point of work.
Adaptation - Answers- 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.
What is Scrum? - Answers- A framework within which people can address complex
adaptive problems, while productively and creatively delivering products of the highest
possible value.
