Motivation
• The first graphic explanation that I´ve seen about an
agile method… (spaghetti code anyone)?
Agustin Villena -
Source: Extreme Programming Explained, Kent Beck, 1999
Goal
• Define a coherent & simple model to describe,
coach and compare Agile Methods
• It has been refined through 12 years of agile
practice and teaching
Agustin Villena -
Agile as a Fractal
of Feedback Loops
• Living creatures ecosystems evolve in interaction
with their environment
– (Humberto Maturana)
• Feedback loops are the natural way to learn &
adapt
Agustin Villena -
Hypothesis• Agile Methods are composed of feedback loops that
evolve and synchonize– Business Problem with solution (Planning Game)
– Team Member with Team (Katas, Standup Meetings, Visual Workplace)
– Feature with Code (ATDD, TDD)
– New Code with Production Code (Devops)
– Team with their Workflow (Kanban)
• Those feedback loops are some version of the Plan-Do-Check-
Act Cycle

Agile is like a guided missile
• Fail fast.
Intentar algo simple, probar si funciona, y continuar.
