Fire, the animating spirit
Scenes by the fire
A hierarchical system of sense
During the Renaissance, the five senses were understood to form a hierarchical system from the highest sense of vision down to touch. Vision was correlated to fire and light, hearing to air, smell to vapour, taste to water, and touch to earth.
The totality of its sensory stimulation
Perhaps the human fascination with fire stems from the totality of its sensory stimulation. The fire gives a flickering and glowing light, ever moving, ever changing. It crackles and hisses and fills the room with the smells of smoke and wood and perhaps even food. It penetrates us with its warmth. Every sense is stimulated and all of their associated modes of perception, such as memory and an awareness of time, are also brought into play, focused on the one experience of the fire. Together they create such an intense feeling of reality, of the "here and nowness" of the moment, that the fire becomes completely captivating.
Manifesto for Agile Software Development
We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:
- Individuals and interactions over processes and tools
- Working software over comprehensive documentation
- Customer collaboration over contract negotiation
- Responding to change over following a plan
That is, while there is value in the items on the right, we value the items on the left more.
Deliver early and continuously
Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
Welcome changing requirements
Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.
Self-organizing teams
The best architectures, requirements, and designs emerge from self-organizing teams.
Technical excellence and good design
Continuous attention to technical excellence and good design enhances agility.
Agility and sustainability
Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
The amount of work not done
Simplicity—the art of maximizing the amount of work not done—is essential.
The primary measure of progress
Working software is the primary measure of progress.
Build projects around motivated individuals
Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
Deliver working software frequently
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
Business people and developers must work together daily throughout the project.
Face-to-face conversations
The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
Reflect, tune, adjust
At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
