4. Responding to change over following a plan

What is “Agility”?
•Effective (rapid and adaptive) response to change
• Effective communication among all stakeholders
• Drawing the customer onto the team
• Organizing a team so that it is in control of the work
performed
Yielding …
• Rapid, incremental delivery of software
5
An Agile Process
•Is driven by customer descriptions of what is required (scenarios)
• Recognizes that plans are short-lived
• Develops software iteratively with a heavy emphasis on
construction activities
• Delivers multiple ‘software increments’
• Adapts as changes occur

Agility Principles -I
1. Our highest priority is to satisfy the customer through early and
continuous delivery of valuable software.
2. Welcome changing requirements, even late in development. Agile
processes harness change for the customer's competitive advantage.
3. Deliver working software frequently, from a couple of weeks to a
couple of months, with a preference to the shorter timescale.
4. Business people and developers must work together daily throughout
the project.
5. Build projects around motivated individuals. Give them the
environment and support they need, and trust them to get the job done.
6. The most efficient and effective method of conveying information to
and within a development team is face–to–face conversation.

Agility Principles -II
7. Working software is the primary measure of progress.
8. Agile processes promote sustainable development. The sponsors,
developers, and users should be able to maintain a constant pace
indefinitely.
9. Continuous attention to technical excellence and good design enhances
agility.
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.

Human Factors
• Theprocess molds to the needs of the people and team, not the
other way around
• key traits must exist among the people on an agile team and the
team itself:
– Competence.
– Common focus.
– Collaboration.
– Decision-making ability.
– Fuzzy problem-solving ability.
– Mutual trust and respect.
– Self-organization.
