Agenda: Safety Analysis of Telltale use case

Questions from Pete

• What level of maturity does a system need to have achieved for us to apply STPA?
  • Can be applied at any stage, and used to iteratively improve a design / implementation
• Can we use it to derive FTTI Fault Tolerant Time Interval?
  • The time window that we have available between a fault expressing itself as a failure and the violation of an associated safety goal
• Should the Display be part of the scope?
  • We will start by assuming that the display is an external component

Other GUI Processes

• Represents other processes that might interfere with the correct rendering of the telltale notifications How does the checker notify the driver that there is a problem?
• Sends an (unknown) signal to the kernel to blank the display

Daniel: What is a useful way for us to represent our work results?

• Store the artifacts we create in the repo
  • Paul to add those shared in the meeting
• Also include regular updates describing our discussions
  • Daniel volunteered to help with this
