The dragline
A metropolis for hydrocarbons
An oil refinery suggests the image of a metropolis for hydrocarbons, the pipe manifolds like expressways, the distillation towers like skyscrapers.
A haunting, syncopated music
"Rappers" on the roof of the electrostatic precipitator knock the accumulated dust free, letting it fall into the storage hopper. Each rapper is the size and shape of a baseball bat. Inside is an electromagnet that pulls a steel plunger upward, then allows it to fall again, producing a sharp knock. The rappers are energized at seemingly random intervals, producing a haunting, syncopated music. (The rhythm seemed more modern jazz than rap.)
One-machine policy
Today population forecasts are based on extensive and reliable data. However, no such demographic base exists for the world's growing population of machines and devices. Now may be the time to take machine demography seriously and enter into real discussions about machine population control.
An enormous machine
The couple of years in question here saw one of the largest bureaucracies anywhere undergo a convulsion in which it tried to reconceive itself as a non- or even anti-bureaucracy, which at first might sound like nothing more than an amusing bit of bureaucratic folly. In fact, it was frightening; it was a little like watching an enormous machine come to consciousness and start trying to think and feel like a real human.
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.
