  Context: New software development patterns are emerging aiming at
accelerating the process of delivering value. One is Continuous
Experimentation, which allows to systematically deploy and run instrumented
software variants during development phase in order to collect data from the
field of application. While currently this practice is used on a daily basis on
web-based systems, technical difficulties challenge its adoption in fields
where computational resources are constrained, e.g., cyber-physical systems and
the automotive industry. Objective: This paper aims at providing an overview of
the engagement on the Continuous Experimentation practice in the context of
cyber-physical systems. %To provide an understanding of what is the
state-of-the-art of the Continuous Experimentation practice in the context of
cyber-physical systems, and what is the practitioners' feedback about this
practice. Method: A systematic literature review has been conducted to
investigate the link between the practice and the field of application.
Additionally, an industrial multiple case study is reported. Results: The study
presents the current state-of-the-art regarding Continuous Experimentation in
the field of cyber-physical systems. The current perspective of Continuous
Experimentation in industry is also reported. Conclusions: The field has not
reached maturity yet. More conceptual analyses are found than solution
proposals and the state-of-practice is yet to be achieved. However it is
expected that in time an increasing number of solutions will be proposed and
validated.
