- 20. Open Source = Agile ? • Open Source shares the same values: • Individuals and interactions • Working software • Customer collaboration • Responding to change
- 21. Principles behind... • 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

- 49. Release Cycle
- 50. https://wiki.openstack.org/wiki/ReleaseCycle Release Cycle • A coordinated 6-month release cycle with frequent development milestones. • The Release Cycle is made of four major stages: • Planning • Implementation • Pre-Release • Release
- 51. Free?
- 52. Release Cycle • Note: Each core project is free to choose a different release cycle contents, as long as they submit a version for the common OpenStack release at the end of the cycle. However, unless they have a good reason to differ, they are strongly encouraged to follow the common plan that is described in this document.
- 53. Agile?
- 54. Release Cycle • Note: Nothing prevents you to do a particular task outside of the designated stages.You can design during the QA stage. You can write new code on release week. The release cycle just gives you a general idea of what's the general team focus, it is not meant to restrict you in any way.
