A short story about
Finish a step before moving to the next
You do not revisit a previous step
It can take a lot of time to deliver
You better do it right before moving forward
Can we do it better?
The Agile Manifesto
The 17th of February of 2001, 17 people meet and proposed an alternative...
They proposed values and principles
But instead of a new process
Individuals and interactions
over processes and tools
over comprehensive documentation
over contract negotiation
Responding to change
over following a plan
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.
And then, we got some implementations...
