Agile Manifesto
We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:
- Individuals and interactions over processes and tools
- Working software over comprehensive documentation
- Customer collaboration over contract negotiation
- Responding to change over following a plan
That is, while there is value in the items on the right, we value the items on the left more.
Scrum
Scrum is a project management methodoloogy that was founded in the early 1990's and is designed around the Agile Framewwork for software development.
The Scrum framework consists of Scrum Teams and their associated roles, events, artifacts, and rules. Each component within the framework serves a specific purpose and is essential to Scrum’s success and usage.
Specific strategies for using the Scrum framework vary and are described elsewhere. The rules of Scrum bind together the events, roles, and artifacts, governing the relationships and interaction between them.
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.
Three pillars uphold every implementation of empirical process control: transparency, inspection, and adaptation.
Transparency
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.
Inspection
Scrum users must frequently inspect Scrum artifacts and progress toward a 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
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.
