3. DevOps and development lifecycle management

The development lifecycle consists of a number of different phases. The length of each phase depends on the development methodology you use (Waterfall, Agile, etc.). These phases can include Analysis, Design, Specification, Planning, Development, Testing, Deployment and more.

Depending on the complexity of your specific Sitecore implementation – or general Sitecore governance model – the need for automation of all or some of processes in the Application Lifecycle phases can vary greatly. Take, for example, the differences between a small in-house development team independently working solely and consistently on a single Sitecore implementation, a Sitecore implementation partner trying to consistently develop and maintain numerous Sitecore implementations and an enterprise product owner trying to govern a Sitecore implementation with multiple implementation partners and design agencies working together. In other words, in some governance models, it would be acceptable to have documented and manually executed processes, where as in others it could be catastrophic to be unable to repeat processes consistently.

Therefore, DevOps can be as much a challenge of identifying and prioritizing the important processes to automate as it is the task of actually implementing the automation.

In the scope of this document we will only look into DevOps processes in specific phases of the application lifecycle:

Development
in which the features or modules are being built
Build
or Integration in which the implementation is put together as a single testable package
Testing
in which the features or integrated package are tested against the specifications
Deployment
in which the package is ultimately deployed onto the production environment

Please note that this is in no way an in-depth look at the DevOps or a governance model for these phases, but rather is an inspection of some of the Sitecore related processes and activities in these phases.
