10 simplicitythe art of maximizing the amount of work

10. Simplicity—the art of maximizing the amount of work not done—is essential.
11. The best architectures, requirements, and designs emerge from self-organizing
teams.
12. At regular intervals, the team reflects on how to become more effective, then
tunes and adjusts its behavior accordingly.

Section 2
Although originating in the software industry, these principles have since spread to many other industries.
This embodiment of mindset, values, and principles defines what constitutes an agile approach. The various agile
approaches in use today share common roots with the agile mindset, value, and principles. This relationship is shown
in Figure 2-3.
Figure 2-3. The Relationship Between the Agile Manifesto Values, Principles, and Common Practices
As shown in Figure 2-3, the model, inspired by Ahmed Sidky, articulates agile as a mindset defined by the Agile
Manifesto values, guided by the Agile Manifesto principles, and enabled by various practices. It is worth noting that
while the term “agile” became popularized after the Manifesto, the approaches and techniques being used by project
teams today existed before the Agile Manifesto by many years and, in some cases, decades.
Agile is a mindset defined by values, guided by principles, and manifested through
many different practices. Agile practitioners select practices based on their needs.

Figure 2-4. Agile is a Blanket Term for Many Approaches
Agile approaches and agile methods are umbrella terms that cover a
variety of frameworks and methods. Figure 2-4 places agile in context and
visualizes it as a blanket term, referring to any kind of approach, technique,
framework, method, or practice that fulfills the values and principles of the
Agile Manifesto. Figure 2-4 also shows agile and the Kanban Method as
subsets of lean. This is because they are named instances of lean thinking
that share lean concepts such as: “focus on value,” “small batch sizes,”
and “elimination of waste.”

Is agile an approach, a method, a
practice, a technique, or a framework?
Any or all of these terms could
apply depending on the situation.
This practice guide, uses the term
“approach” unless one of the other
terms is obviously more correct.

Section 2
In general, there are two strategies to fulfill agile values and principles. The first is to adopt a formal agile approach,
intentionally designed and proven to achieve desired results. Then take time to learn and understand the agile approaches
before changing or tailoring them. Premature and haphazard tailoring can minimize the effects of the approach and thus
limit benefits. (See Appendix X2 for Tailoring Considerations).
The second strategy is to implement changes to project practices in a manner that fits the project context to achieve
progress on a core value or principle. Use timeboxes to create features, or specific techniques to iteratively refine
