ALM Best practices: Quality standards and DevOps keep the trains on time

German transport company Deutsche Bahn believe in and invests in application quality. Not only does software play a critical role in rail traffic safety, it also powers core business activities. For instance, external rail companies use a Deutsche Bahn portal to book train paths on the company’s rail network. Any downtime can jeopardize train path sales and have major impact to Deutsche Bahn’s revenue.


To optimize application quality and ensure business continuity, Deutsche Bahn’s IT service provider, DB Systel, has worked extensively over the past several years towards a standardization of their functional and performance testing processes and worked to make them more transparent across projects. They implemented HP Quality Center as the foundation of a comprehensive test platform, replacing all other tools.   


“Although we had already defined comprehensive management processes, we still needed a software platform that worked in an equally standardized way,” explains Klaus Metzlaff, head of the Development Centre, Quality Assurance and responsible for central process management in the testing department at DB Systems.


Having a uniform error management system with a comprehensive error database has significantly reduced repeat errors. And standardizing test and quality practices has enabled DB Systel to move from CMMI level 2 to CMMI level 3.  Productivity is improved now that several employees can work in parallel on the same tests and reuse test cases and error information. And reporting and software development costs are lower. 


Embracing the concept of improving practices between development and operations to attain better overall application reliability, performance and security, the DB Systel team is also standardizing the way they manage incidents back into the development team to further increase quality and productivity.


DB Systel uses an HP solution for incident management, future events registered by this tool may flow directly back to the HP Quality Center error management system. This means that problems resulting from software errors are remedied at their root.
