What is „Agility“?
„Agility is the ability to both create and
respond to change in order to profit in a
turbulent buisness environment.“
[Jim Highsmith, Agile Software Development Ecosystems, Preface XXIII]

Chaordic – Chaos mixed with order
• Natural blend of Chaos and Order
• Most organisations and projects exhibt
chaordic structures
• Is about self-organisation and self-
governance, evolutionary like nature
• Often used to describe agile software
development processes.

5. JASS 2006
Management and Developing
before Agile
• Countermovement to heavy and
bureaucratic software development
processes
• Waterfall
• V-Modell
• Beginning in the early 1990ies, became
publically known in 1999 with Kent Becks
„Extreme Programming“

Agile Manifesto
• Individuals and interactions over
processes and tools
• Working software over comprehensive
documentation
• Customer collaboration over contract
negotiation
• Responding to change over following a
plan
[Source: Agile Manifesto, http://agilemanifesto.org, 3/29/2006 ]

7. JASS 2006
This does NOT mean...
• ... processes and tools don‘t matter.
• ... that we need no documentation.
• ... that we need no contracts.
• ... make a plan and follow it is obsolete.

8. JASS 2006
Principles
• Keep it { simple, small } and { stupid,
straigthforward, smart } (KISS)
• Use resources carefully
• „Chaordic“ nature of projects and
organisations

Flavours of Agile Development
Extreme Programming
Scrum
Crystal

Extreme Programming
• iterative
• adaptive
• continous integration/build
• became generally known with Kent Beck

11. JASS 2006
Scrum
• living backlog of prioritized work to be
done
• Completion of a fixed set of backlog items
in a series of short iterations (sprints)
• Brief planning session to define backlog
items for the next sprint
• Retrospective for all team members to
reflect the last sprint

12. JASS 2006
Crystal
• Different methods for different group sizes
• Common feature set:
– Frequent Delivery
– Reflective Improvement
– Close Communication
• „Crystal Clear“ most known
