This morning I woke up with a fresh insight about how to structure part of a safety argument for the automatic charging system we are working on. The argument would help to guarantee the safety of the vehicle using our charging system while at the same time simplify our initial design.
As I arrive at work, I quickly get myself a cup of coffee and start drafting the argument in the safety concept. I then schedule a meeting with the hardware and software architects to work out the implications for their design.
Early in the afternoon, a weekly teleconference with the safety manager of our customer is planned. I intend to share some insight into some new risk we recently identified. To get up to date on this risk, I quickly pay a visit to the lab where my colleague is busy with a test setup. The setup uses one of the prototype hardware boards that were manufactured at our production facility earlier that week to check the effect of a very short interruption in the power supply. He shows me that the effect is not as severe as initially estimated but could result in some undefined behavior of our software. I love the symbiosis between hardware and software!
The rest of the morning I work on a fault tree analysis of the design of the safety-related hardware and review part of the software code one my colleagues wrote.
After having had lunch and a nice refreshing walk, the meeting with the customer is rather uneventful. During the meeting though I get a phone call from a colleague, so I call her back afterwards. She is asking if I am available for a review later this week to provide feedback on their safety plan for the wall box project, which is a few steps behind in the development process.
In the afternoon, a colleague from our sales department comes by to ask about the implications of an ASIL B requirement a potential new customer has requested. I briefly explain the extent of the development processes and resources required to comply with ISO 26262 and agree to sit in on a meeting with this customer next week for further explanation.
After the meeting I get a call my 2-year-old son is not feeling too well. So, I pack my laptop, leave a little earlier than normal, pick him up, and finish my work for the day later that evening from the comfort of my kitchen table.
