下面是 DevOps 的敏捷开发理念
software development: OODA (Observe, Orient, Decide, Act) loop (观察、定位、决定、行动)
- Observe: You start with observing business, market, needs, current user behavior, and available telemetry data.
观察：你首先从观察业务、市场、需求、当前用户行为以及可用的遥测数据开始
- Orient: Then you orient with the enumeration of options for what you can deliver, perhaps with experiments.
定位：然后，你通过列举你能提供的东西来定位方向，或许还需要通过实验来进一步确定
- Decide & Act: Next, you decide what to pursue, and you act by delivering working software to real users.
决定&行动：接下来，你决定要追求什么，并通过向真实用户交付可运行的软件来付诸行动
Originally designed to keep fighter pilots from being shot out of the sky, the OODA loop is an excellent way to think about staying ahead of your competitors.
最初的设计是为了防止战斗机飞行员被击落，OODA循环是一个很好的方式来思考保持领先于你的竞争对手。
We recommend you use data to inform what to do in your next cycle. Many experience reports tell us that roughly one-third of the deployments will have negative business results. Approximately one-third will have positive results, and one-third will make no difference. Fail fast on effects that do not advance the business and double down on outcomes that support the business. Sometimes the approach is called pivot or persevere.
我们建议您使用数据来告知下一个周期要做什么。许多经验报告告诉我们，大约三分之一的部署将产生负面的业务结果。大约三分之一会有积极的结果，三分之一不会有什么不同。对于那些不利于业务发展的影响，要迅速放弃；而对于那些有助于业务发展的成果，则要加倍投入。有时，这种方法被称为“以不变应万变”或“坚持不懈”。
Strive for validated learning (争取有效的学习)
How quickly you can fail fast or double down is determined by your cycle time. Also, in how long that loop takes, or in lean terms. Your cycle time determines how quickly you can gather feedback to determine what happens in the next loop. The feedback that you collect with each cycle should be factual, actionable data. We call it validated learning.
你能否快速试错或加倍下注，取决于你的循环时间。此外，在精益术语中，也指循环所需的时间。你的循环时间决定了你能多快收集反馈，以确定下一个循环会发生什么。每个循环收集的反馈都应该是事实性的、可操作的数据。我们称之为 “有效学习”
目标：
- You shorten your cycle time by working in smaller batches. / 小批量
- Using more automation. / 自动化
- Hardening your release pipeline. / 强化
- Improving your telemetry. /遥测能力
- Deploying more frequently. / 频繁地部署
Before：horizontal team
after：vertical team
project teams -> feature teams
