Caitlin Kalinowski: evaluation

Transcript context

…You're going to be a hot commodity in this market now that you're a free agent, but on the flip side of that, I want to take us to Fail Corner. I feel like someone building hardware physical things has some great fail stories. Is there one story of something you built, something you worked on that failed and something you learned from that experience? This is a great question and not a comfortable one. One of my favorite failures was actually on the Quest One. It was around EVT, so halfway through the Quest One, and we found out that we had gone from five cameras to four for cost reduction. We talked a little about this. We needed to reduce the price so more people could buy them. And what happened was it was right before Christmas and I heard from the lead on the team that does computer vision and he said, "Oh my gosh, the data from the cameras isn't working and we can't get a lock on where the person is using the headset. " And so we looked into it and we realized that their interpretation of our spec and our interpretation of our spec was different. So in engineering, we usually use a plus or minus, like it can go up or down by, in this case I think it was 0.15mm or something like that. And in his world, he was used to having a global, it's within 0.15mm. And so we had a different interpretation of the spec. Now the problem is that our interpretation of the spec meant that he couldn't meet his goals of being able to understand where the headset was in space. And so we had to do a redesign and this is at EVT. So this is pretty much when you want the engineering to be done. What does EVT stand for?…
