Where is the Problem?
![Page 6: Understanding DevOps in simpler way with Continuous Delivery](https://reader034.fdocuments.us/reader034/viewer/2022042611/587dd4ea1a28ab5b5b8b6103/html5/thumbnails/6.jpg)
Rework & Overhead
![Page 7: Understanding DevOps in simpler way with Continuous Delivery](https://reader034.fdocuments.us/reader034/viewer/2022042611/587dd4ea1a28ab5b5b8b6103/html5/thumbnails/7.jpg)
Rework & Overhead
● Developer to QA lag● Developers gets late feedback ● Works on a buggy software● Resulted in REWORK● Developers are paid to write code● Not spend hours writing instruction how deploy,
thats OVERHEAD● That leads to more problems....
![Page 8: Understanding DevOps in simpler way with Continuous Delivery](https://reader034.fdocuments.us/reader034/viewer/2022042611/587dd4ea1a28ab5b5b8b6103/html5/thumbnails/8.jpg)
Leads to more problems
● An INNOVATION problem– We need to deliver more apps, more features, more value.
The business wants more out of IT.
![Page 9: Understanding DevOps in simpler way with Continuous Delivery](https://reader034.fdocuments.us/reader034/viewer/2022042611/587dd4ea1a28ab5b5b8b6103/html5/thumbnails/9.jpg)
Leads to more problems
● An INNOVATION problem– We need to deliver more apps, more features, more value.
The business wants more out of IT.
● A THROUGHPUT problem– We need to deliver value to the organization faster. Our
projects are always behind. My best people are always fighting fires instead of delivering value.

business wants more out of IT.
● A THROUGHPUT problem– We need to deliver value to the organization faster. Our
projects are always behind. My best people are always fighting fires instead of delivering value.
● A QUALITY problem– Our IT projects aren’t as successful as we want them to be. The
results aren’t satisfying the business.

DevOps Defined
DevOps is a culture, movement or practice that emphasizes the collaboration and
communication of both software developers and IT operations professionals
while automating the process of software delivery and infrastructure changes.
