Case study: Techniker Krankenkasse successfully uses Software Maps
How do you keep tens of millions lines of source code in shape? This has been the challenge of Dr. Frank Griffel, Head of IT Systems at Techniker Krankenkasse (technician health insurance), whose brief summary was clear: “I would like to look over the inner workings of our key operational system quickly.” The IT manager found the answer to this question in seereneTM’ solution, which the health insurance now uses to continuously check its central software system “TKeasy”.
Techniker Krankenkasse relies on seereneTM Software Maps
Fourteen years ago, the technicians of Techniker Krankenkasse had taken the self-developed IT architecture “TKeasy” in operation and since held it up to date from a technical, business and architecturally point of view. TKeasy is a Java-based 4-layer application that is intended to deploy the core business of the health insurance company. But 14 million lines of source code and 54 billion object transactions every day turn operation and maintenance into a conceivable challenge – especially with regard to dependency management within the architectural care operations.
How exactly Techniker Krankenkasse has dealt with this challenge by implementing the Software Maps from seereneTM is in detail presented in issue 12/2014 of Business&IT. Allow us, however, to tell about the result: Dr. Frank Griffel and his team would not want to miss Software Maps anymore as they use them to visualize their software environment. “It is impressive to see our system as a large city. Other graphic formats that we had met, are far less intuitive to grasp – not to mention a source code print-out”, says the Head of IT Systems of Techniker Krankenkasse about his use of Software Maps.
