Agile
• Agile — семейство процессов разработки, а не единственный подход в
разработке программного обеспечения, и определяется Agile Manifesto.
• Agile не включает практик, а определяет ценности и принципы, которыми
руководствуются успешные команды.

Kanban
• Работа kanban-команд строится вокруг Kanban-доски, которая используется для визуализации и
оптимизации рабочего процесса.
• Модель Kanban основана на полной прозрачности работы и обсуждении производительности в
режиме реального времени. Поэтому доска Kanban должна стать единственным достоверным
источником информации о работе команды.
