DevOps represents a change in IT culture, focusing on rapid IT service delivery through the adoption of agile, lean practices in the context of a
system-oriented approach. DevOps emphasizes people (and culture), and seeks to improve collaboration between operations and development
teams. DevOps implementations utilize technology — especially automation tools that can leverage an increasingly programmable and
dynamic infrastructure from a life cycle perspective.

A philosophy that brings together operations and development DevOps is an approach that promotes closer collaboration between lines of business, development and IT operations. It is an enterprise capability that enables the continuous delivery, continuous deployment and continuous monitoring of applications. It reduces the time needed to address customer feedback. Development and operations, and even testing, were often siloed in the past. DevOps brings them together to improve agility.

Devops is a cultural movement that changes how individuals think about their work, values the diversity of work done, supports intentional processes that accelerate the rate by which businesses realize value, and measures the effect of social and technical change. It is a way of thinking and a way of working that enables individuals and organizations to develop and maintain sustainable work practices. It is a cultural framework for sharing stories and developing empathy, enabling people and teams to practice their crafts in effective and lasting ways.

為何需要 DevOps ?
: http://www.ithome.com.tw/news/87144
Why DevOps ?藉由將各開發階段自動化以及訊息公
開，幫助企業軟體研發相關部門，解決
傳統流程端對端（End to end）所產生
訊息不對稱，以及協作不順暢的問題，
並且自動化開發流程的每個階段，進而
提升軟體交付的速度。

並且自動化開發流程的每個階段，進而
提升軟體交付的速度。
: http://www.ithome.com.tw/news/87144
Why DevOps ?CIO在雲端時代必須聚焦在總體商業的結
果，了解究竟IT提供企業什麼價值，這包
含三個要點，應用程式部署的速度、衡量
風險、控制成本。如果守著過去開發及營
運模式，對於以上提及的三點將失去競爭
力，也因為如此，傳統的方式必須改變。
: http://www.ithome.com.tw/news/87144
Why DevOps ?
就如同精實開發的精隨，減少不
必要的浪費以及重複性的程序，
做到剛好符合需求。
: http://www.ithome.com.tw/news/87144
Why DevOps ?因此可以減少錯誤發生，開發人員也可以
專注在產生更有品質的程式碼，避免之後
不停的修補程式碼，有更多心力去做一些
有趣的事，我們也從一些客戶案例看到，
開發人員不只更有生產力，他們也更快樂
了，而且良好軟體讓維運更容易。
: http://www.ithome.com.tw/news/87144
Why DevOps ?我們有一些來自客戶的數據，軟體測試
可以減少90％的時間，版本釋出和部署
的頻率可以大幅提升。實際案例顯示，
過去要兩年才能釋出1個新產品，導入
DevOps開發方法後，一年半可以發布
18個成品。
: http://www.ithome.com.tw/news/87144

Why DevOps ?DevOps的一个巨大好处就是可以高效交付，这也正好
是它的初衷。Puppet和DevOps Research and
Assessment (DORA) 主办了2016年DevOps 查报告
中，根据全球4600位各IT公司的技术工作者的提交数
据统 ，得出高效公司可以完成平均每年1460次部
署。与低效 织相比，高效 织的部署 繁200倍，
品投入使用速度快2555倍，服务恢复速度快24倍。
: http://mp.weixin.qq.com/s?__biz=MzA5NzU3Njc5Mw%3D%3D&mid=2651200907&idx=1&sn=862b2c1b0ca650361efd2a46add9b03a
Why DevOps ?
在工作内容的时间分配上，低效者要多花
22%的时间用在 划好或者重复工作上，
而高效者却可以多花29%的时间用在新的工
作上。所以这里的高效不仅仅指公司 出的
效率提高，还指 工的工作 量得到提升。
: http://mp.weixin.qq.com/s?__biz=MzA5NzU3Njc5Mw%3D%3D&mid=2651200907&idx=1&sn=862b2c1b0ca650361efd2a46add9b03a
Why DevOps ?
DevOps另外一个好处就是会改善公司 织文
化、提高 工的参与感。 工 变得更高效，
也更有 足和成就感； 查 示高效 工的雇
推荐值（eNPS:employee Net Promoter
Score）更高，即对公司更加 同。

Leaders need to realize that implementing DevOps means changing the technology system as well as the cultural system. They must acknowledge that both are intertwined and, to be successful, both systems must evolve to drive velocity.”
Learning how to manage and lead by giving people context and information to make better decisions—versus giving them tickets or briefs—is how leaders and teams will thrive.
