"Our team was working on a video recording feature, and we thought that including a passcode would be useful. Surgeons would have exclusive access to the recording tool, and they could ensure that they were the only ones who could start and stop the video.
The feedback we got was an unequivocal no. They told us that they wouldn't care about pushing buttons in that high-stress environment, and that they would probably put the passcode on a sticky note on the device, making it pointless.
We removed the feature because it didn’t add value. It only created friction."
