Act IIn The Beginning...

What Is Agile?

Manifesto, 4 Values, 12 principles...

Manifesto for Agile Software DevelopmentWe are uncovering better ways of developingsoftware by doing it and helping others do it.

Through this work we have come to value:Individuals and interactions over processes and toolsWorking software over comprehensive documentationCustomer collaboration over contract negotiationResponding to change over following a plan

That is, while there is value in the items onthe right, we value the items on the left more.

Principles

Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.

Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.

Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.

Business people and developers must work together daily throughout the project.

Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.

The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.

Working software is the primary measure of progress.

Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.

Continuous attention to technical excellence and good design enhances agility.

Simplicity--the art of maximizing the amount of work not done--is essential.

The best architectures, requirements, and designs emerge from self-organizing teams.

At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.

(This is the sauce...)

Dogma Sucks

Dogma SucksDo not seek to follow in the footsteps of

the wise. Seek what they sought. --松尾芭蕉

The Tao that can be spoken is not the eternal Tao

Hold, Break, Leave

You are a special snow flake...

Just like everybody else...

Act IIIThe Future is Now

the way software is delivered has changed a lot...

...AND THINGS ARE CHANGING FAST RIGHT NOW .

The End of Shrink Wrap

The infrastructure is the application.

The application is the infrastructure.

What are the Best Practices?

How about ‘better than we did yesterday’ practices?

How about ‘better than we did yesterday’ practices?

Or ‘seems like a good idea right now’ practices?

David Christiansenhttp://www.techdarkside.com/

We believe Agile software development is being dumbed down, commodified, and is losing its spirit.

We seek to replace the current name with one having two virtues: first, that it capture more exactly the attitudes originally behind Agile; second, that it

be obscure enough that no one will assume they already know what it means and that—amazingly

enough!—they are already doing it.
