Tools can enable change in behavior and eventually change culture. - Patrick Debois
The technical quality of a software is fundamentally manifested in the source code. To avoid a steady decrease of technical quality during development it is required to measure it on a regular base (continuously on Dev and at least daily for QA). By doing that it is possible to detect and address undesirable rule violations early in the process. The later rule violations are detected the more difficult and expensive it is to fix them. Continuous Delivery tool-chain, span different phases of the development process, with different project roles gaining benefit from this highly integrated toolchain.
