The Economics of Continuos Delivery - Adrian Perreau

Barcelona Software Craftmanship 2017

"Why should you invest in Continuous Delivery? It's expensive, requires tecnical expertise, time and machines... The problem is that without CD you are walking around with a hole in your pocket and the hole is getting bigger... This presentation focusses on the 3 main reasons why the hole is there... and growing. They are the ABC of Continuous Delivery: - Amplification: Deploying takes more time the longer the time between deploys. - Bugs: Bugs are more costly to fix the longer ago they were introduced. - Cost of Delay (CoD): The longer you take between deploys, the longer your cost of delay In the model we present, one can see the costs of integration and deploy are super linear to the number of changes to integrate. In Software Development, the commits that are not yet in production are inventory... and inventory is waste."
