A harmonized multimodel framework for safety environments

Safety critical systems developments are dealing with complex environments especially when they are satisfying with a wide range of models, regulations and standards at the same time. Therefore there is an evident impact in software process improvement (SPI) settings. These multimodel environments are not just specific for critical systems but for a wide set of environments. Some experiences adopting two different standards or models have been reported during these recent years. Basically they are based on mappings between process models at a high level. However these works are appropriated for people with a huge knowledge on two specific standards, but they do not provide a roadmap on how to effectively apply to company settings. This paper is focused on to provide a harmonised framework not only covering practices based process models but also covering products characteristics. In addition we reconcile this framework for safety critical systems.
