  A distributed software control system aims to enhance the evolutivity and reliability by sharing responsibility between several components. Disadvantage is that detection of problems is harder on a significant number of modules. In the Kaizen spirit, we choose to continuously invest in automatism to obtain a complete overview of software quality despite the growth of legacy code. The development process was already mastered by staging each lifecycle step thanks to a continuous integration server based on JENKINS and MAVEN. We enhanced this process focusing on 3 objectives : Automatic Test, Static Code Analysis and Post-Mortem Supervision. Now the build process automatically includes the test part to detect regression, wrong behavior and integration incompatibility. The in-house TANGOUNIT project satisfies the difficulties of testing the distributed components that Tango Devices are. Next step, the programming code has to pass a complete code quality check-up. SONAR quality server was integrated to the process, to collect each static code analysis and display the hot topics on synthetic web pages. Finally, the integration of Google BREAKPAD in every TANGO Devices gives us an essential statistic from crash reports and allows to replay the crash scenarii at any time. The gain already gives us more visibility on current developments. Some concrete results will be presented like reliability enhancement, better management of subcontracted software development, quicker adoption of coding standard by new developers and understanding of impacts when moving to a new technology.
