Automation can have a huge impact on the overall performance of the couple user/system. Function and Tasks allocation and Authority sharing are “classical” key elements exploited in the design of automation. This position paper advocates the need for dealing with additional dimensions namely Control Transitions, Resources and Responsibility. In this position paper, we discuss the benefits of embedding all those dimensions for designing automation and reasoning about automation designs. We present on a simple case study from the automotive domain how those dimensions can concretely be applied. Lastly, we discuss how they contribute to the fours Is of the workshops: Intelligibility, Intervention, Interplay and Integrity.
