Systems Engineering and Motherhood - It's as if they probe each other within me to bring interesting realizations into my notice.
Many years ago I worked for developing car's Body Control Module - the ECU that's famously known for always dealing with more than what it is supposed to!
What if someone splashes hot tea at it?
What if the ECU's temperature rises suddenly and how it shall still stick to the ECU's housing?
.
.
What if someone does this, and that, and what not?
After many years, one day during our road-trip, one of my kids casually bent under the dashboard, removed the label from our car's BCM (the same one that I worked for, by the way) and he then stick it in my palm. This was never a use case in our debates back then!
Once the label was removed, I could never place it back as perfectly as I thought we had made it to be!
