The International Conference of Program Comprehension (ICPC) 2015 honored the publication Concise and Consistent Naming by Dr. Markus Pizka und Dr. Florian Deissenboeck (CQSE GmbH) with the Most Influential Paper Award and thus one of the most influential publications of the last 10 years. The publication shows how important the naming of program components is for actual maintenance, provides clear quality criteria and a solution for automated testing with tools.
The publication Adaptation of Large-Scale Open Source Software - An Experience Report by Dr. Markus Pizka was awarded the Best Paper Award at the 8th European Conference on Software Maintenance and Reengineering (CSMR) in March 2004, in Tampere, Finland. The publication discusses the risks of the new development of software as well as the chances of expanding and adapting existing software from the perspective of many years of experience.
