How do we deliver software to users as quickly as possible? We have to focus on the build, test and release process. Fast delivery is also useful because it allows to verify if features and bugfixes; it also minimizes the time of feedback from the client. Releases need to be automated and frequent. Software doesn't have to be waiting uselessly until it is deployed.

The keys to an iterative development process are the prioritization of the most valuable features and parallelization of objectives by assigning them to the adequate number of developers.
