  Non-functional properties, such as energy, time, and security (ETS) are
becoming increasingly important in Cyber-Physical Systems (CPS) programming.
This article describes TeamPlay, a research project funded under the EU Horizon
2020 programme between January 2018 and June 2021. TeamPlay aimed to provide
the system designer with a toolchain for developing embedded applications where
ETS properties are first-class citizens, allowing the developer to reflect
directly on energy, time and security properties at the source code level. In
this paper we give an overview of the TeamPlay methodology, introduce the
challenges and solutions of our approach and summarise the results achieved.
Overall, applying our TeamPlay methodology led to an improvement of up to 18%
performance and 52% energy usage over traditional approaches.
