In this episode with Mike Iarossi and David Troness, David provides a detailed look at the causal analysis of rear-end collisions. He walks step-by-step through some common approaches to causal analysis while sharing a progression through 5-whys, Fishbone Diagrams, Driver Trees, and then eventually into the Physics Based Cause Tree. 

Eventually he moves past the physics of stopping and begins to uncover the human side of the causal elements implicated in rear-end collisions. He opens up some concepts from Human Factors Engineering and starts to unpack conceptual objects like perception, reaction, and eventually motivation. 

During the conversation David starts to chip away at assumptions and shares his own personal list of the top 20 Bad Assumptions, things like:

People will always act in a seemingly logical way in response to their own environment.The “good of the company” is always the main concern of employees. People always want to do the best they can. 

David then goes on to talk about how once the problem landscape is decomposed into its different component parts we are able to begin using different TRIZ techniques to overcome contradictions and solve some seemingly impossible problems. 

And while this is only a first pass and the overall causal analysis for rear-end collisions is still a work in process, it shows some exciting possibilities for coming up with some new industry leading solutions.

David Troness    00:00:00    But then what that takes you to you’ve set up all of these things are different contradictions that these three boxes for each one, now you can use Tris potentially just say, to look at how have other brilliant inventors or, you know, people really solve impossible problems. How did they overcome that type of dilemma? Not that specific line, but their instance. I wanted a distance to be long for one reason. And I wanted it to be really short for another reason. And I have both, but without just leisurely picking some number halfway in between 

Intro    00:00:52    the insane transformation podcast and who would’ve thought a handful of texters and a pink unicorn sketchbook is all that it would take to disrupt your industry. 

Mike Iarossi    00:01:17    Welcome back to the insane transformation podcast. So you are here with Mike Iarossi and David Troness. So Hey David, how are you 

David Troness    00:01:27    Doing well? Yeah, I’m, uh, uh, boiling over here. It’s super hot in Phoenix. Um, I gotta learn what the conversion is to Celsius for you guys, but anyway, it’s about a hundred degrees here. What is that? 40 or something? 

Mike Iarossi    00:01:43    100 degrees. Yeah, I think it’s probably around 38 or something like that. Um, yeah. Close. It’s pretty hot. Wow. Okay. And you’re wearing a sweatshirt. Yeah, that’s right. I think for us it’s uh, now I’m going to give you, I’m going to give you it in Celsius. I think it’s about 1314, which, uh, jeez, good luck on that. It’s it’s cold. Yeah. 

David Troness    00:02:04    Oh, that’s wonderful. Um, so yeah. Good doing good. Uh, yeah. I’m, I’m, uh, I look forward to this because I think it might be interesting to sort of review is something I’ve been thinking of as sort of an enhancement to the way we look at tough problems. So, yeah. 

Mike Iarossi    00:02:32    So this is you sort of thinking about, we’re looking at how to ta
