@meenakshi, I think continuous improvement is a must in any organisation.If you are advanced users of SCM doing a lot DevOps already, maybe just point that out. But there might be things in DevOps that you are not doing yet and want to evaluate whether they are suitable to you or not. I usually don't mind how things are labeled.

@meenakshi, tools often change culture/process. And DevOps practices do need some level of culture and process change. I have seen consultants promoting DevOps and continuous deployment using tools to impact culture/processes directly.
The book talks about small teams, communication through interface "only" and applying agile and SE principles to operation side in the early chapters.

@Sitarama, the whole book is trying to answer that question. :-} More seriously, we believe DevOps practices and the requirements of continuous deployment will have major implications on the product architecture (e.g. microservice architecture may suit better in some instances), team structure (which is closely related to product architecture . Conway's law) and monitoring/operation infrastructure architecture.

DevOps is heavily using SCM. There is a distinction in Devops about continuous "delivery" and continuous "deployment", with the latter including automated deployment into production environment. If you are using SCM practices to help automate deployment to production environment and manage the scripts/code for setting up your environment/infrastructure (as in infrastructure-as-code"), then there is not much difference between SCM and DevOps. Puppet and Chef are configuration management software.

Tim, thanks for sharing this. All good points.

DevOps includes a wide range of practices. It is difficult to say what practices are more essential and a must. Some may argue continuously deploying into production environment is not a choice for them. But the overall principle/philosophy should be a must! :-}
