Lifecycle

在日新又新的生態系中，專注於軟體上，並將其視為是值得關照、關注和深思的產品。

我們的軟體開發週期為2週，或少於2週。
- Culture
我們的軟體開發週期是以將能正常運作之軟體異動發佈，並部署至正式運行環境來界定的。
Iterative development and process optimization depends on repeatedly performing the critical functions of building and deploying software. The more it's done, the better it's understood, the easier it is to improve and automate.
- Culture
- Measurement
我們一旦發現缺陷，會先暫停開發工作，評估缺陷以決定修復它的優先順序
- Culture
開發人員或產品負責人（product owner）都能夠將我們的產品部署到正式運行環境。
The focus here is empowering the most informed to perform the task. Someone intimately familiar with a change is best positioned to evaluate its performance and correctness. Developers and POs should be empowered to measure and visualize the operation of the change as well, in order to give them a holistic view of the changed system.
- Culture
- Automation
在自動化部署至正式運行環境之前，我們都有進行自動化測試。
Production deploys can still be manually initiated in cases where a signoff is required, yet the testing, deployment process and validation should be entirely automated to ensure consistency, accuracy and optimal speed. Automating deploys means no copy and paste, less security risk, more auditability, more confidence.
- Automation
- Testing
我們的系統組態（configuration）設定是自動化的。
Friends don't let friends manually configure systems.
- Automation
我們所部署的系統組態（system configuration）是不可變的（immutable）。
Immutability is an ideal state as it allows operations to focus on optimizing consistent and predictable systems.
- Automation
我們發佈和部署的自動化沒有被環境綁定。
To avoid fragmentation or repetition, it's best to limit environmental differences to variable values only.
- Automation
- Testing

Organization

提供一個具備互動與凝聚力的組織架構，作為協作與生產力（工作效率）的後盾。

我們擁有的領域專業知識與經驗並不會只侷限在某些人員身上。
If you're lucky, you're surrounded by experts. Ideally, they're not just islands of knowledge and responsibility, but part of a peer group within the organization.
- Culture
- Sharing
針對異動（changes），我們允許進行跨部門或同儕之間的審查（review）
- Culture
- Sharing
- Testing
我們的組織是圍繞著跨職能團隊進行配置的。
Cross-functional teams are more empowered to build and deploy their own software without being hindered by constraints. They also avoid an 'us vs them' effect of siloed functional teams, learn from, and foster awareness and empathy for eachothers priorities and interests.
- Culture
我們的團隊是以客戶和產品為導向的。
Customer focus helps align teams towards valuable goals, and keeps development and engineering zeroed in on delivery and processing feedback.
- Culture
我們會定期審查（review）優先事項。
- Culture
- Sharing
我們的開發人員能夠自助自理在類正式運行的系統上工作並進行測試。
- Automation
- Testing
我們的開發人員能夠自助使用類正式運行環境的資料（數據）進行工作與測試。
- Automation
- Testing
我們的開發人員能夠自助存取在建置和測試軟體時所需的一切相依性（dependencies）。
- Automation
- Testing

Process

擁有精心打造的儀式（老規矩），培養一貫與信心，能夠為持續改善提供一個框架。

我們的組織遵循敏捷開發實踐。（Agile Development）
To realize the full power of a focus on DevOps, feedback and regular iteration are critical. DevOps is built on agile.
- Culture
我們已在團隊內實行「不咎責的事後檢討」（blameless postmortems）
Focus on learning and continual improvement. This is the human equivalent of focusing on MTTR vs MTBF. Read: John Allspaw's great article on Etsy's process
- Culture
- Sharing
我們定期檢查軟體交付過程中的各種限制。
- Culture
我們的系統組態（system configuration）有進行版本控制。
- Automation
- Testing
我們的文件（documentation）有進行版本控制，並且是團隊共享的。
- Sharing
我們會維護一份任務待辦清單，所有團隊成員都可以查看並提供意見與評論。
我們已在團隊內實行 TDD 或 BDD
- Testing
我們會將程式碼（支線）合併到主線來測試我們的異動
Until you prove your code isn't a destructive regression, it shouldn't be deployed for someone else to discover. Automated testing and frequent merging should catch most of these issues, and make sure you don't find out about problems from someone else - or worse, Twitter.
- Testing
我們會比照正式運行環境的負載量以及使用模式，來測試我們的軟體更動
