Agile

Agile solves the problem of planning software as if requirements never change. It favors short feedback loops, working software, and adaptation over large up-front plans that may become obsolete.

Where it fits

Agile belongs in software management and delivery methodologies. It is a family of values and practices rather than a single process.

Motivation

Software work contains uncertainty. Agile tries to reduce risk by delivering in increments, learning from users and stakeholders, and adjusting plans based on evidence.

Subconcepts

Iteration

A short delivery cycle used to plan, build, review, and adapt.

Feedback loop

A mechanism for learning whether the team is building the right thing in the right way.

Common mistakes

• Treating Agile as ceremonies without feedback.
• Ignoring architecture and quality in the name of speed.
• Confusing flexibility with lack of discipline.
