IMO V model is broken. It tries to be linear/waterfall but actually degrades into iterative by connecting the top of the V with the esoteric "Validation" backpropagating through the V to the original requirements. This builds up floating-requirement-error that eats away unnecessarily at margins (requirements must be within capability and the gap between those circles is that floating requirement error). Being agile and defining interfaces between systems rather than constraining the input/output of each system would allow for early testing to determine which system has more slack/can achieve tighter requirements towards the objective. This would result in a distillation of our concepts based on the available low level requirements and then we'd kinda meet in the middle where high-level concept meets requirements. Not sure how Validation would be solved but I feel like it may occur at that point where the two meet (earlier than in the V model). It would mean that trade studies and concepts would be less influential over requirements and we could be more operationally inclined like an industrial engineer. I rhetorically ask: If us systems engineers are doing non-linear optimization, why are we trying to linearize the process just for operations to try and parallelize & change schedule?

This lecture is so fucking good it's unreal. This is what I love about systems engineering: "the partial of everything with respect to everything." For most people, education is a narrowing process, you slowly specialize, alienating yourself from everyone that isn't working on your niche subject so that, eventually you become master of the world's smallest perspective! You become expert of the world's tiniest field, compelling right? Eventually, at a certain point into your PhD, you finally realize that you can no longer coherently answer the question, "what is it that you're studying?" when out on a date. You can't even communicate what it is that you spend half of your waking hours doing. You have to resort to complicated jargon because you don't understand the bigger picture, you have to be esoterically technical because for you there is no wider generality that other people can relate to, and just think about how lonely that life is, just think about it. You eventually become that sort of amateur astronomer that only knows about the star tracker. You don't know about attitude control or Kalman filters, you don't know that everything feeds back into everything else, so you spend your days in a sort of cozy somber sliver of reality. Every once in a while, a system's engineer comes shining into your dark den and asks you (yes you alone, his pathetic subject, a tiny shadow which has taken refuge at the furthest distance from the imperial sun) a question, and you obsequiously respond in your obscure moon language and you (forever circumscribed by the greater reality) sit and wonder.

It's very true that PhD. is actually blocking you from seeing the big picture . But at the same time touching everything doesn't give you the details . And if you don't apply first rule of thinking and breaking down the system into details and understand the core principles of how they made it will be difficult to have a better definition of your system. So, although you have a perspective that suits you to appreciate what you are doing and what you want to persuade for the future, you always need PhD level details to build a system from bottom up. So, the system and PhDs are equally needed to have a better system

Gentry Lee, I hope that this gets your attention. I have developed a propulsion system that can get us to Mars in less than a day. Do I have your attention yet? I have successfully converted centrifugal force into directed thrust in a completely closed unit, and it will continually accelerate in space. I have a working proof of concept prototype and I have just started a limited scope partnership with someone who is building me the practical purpose prototype. I started this project in 1981. I have about $900K into it at this point. My prototype is a similar shape to a flying saucer. That shape is functional. Have you ever wondered why they are that shape? I know why. In June 2018, I took my prototype to my nation's capital, Ottawa, to meet with two government officials who were tasked with evaluating my project. One of these guys is a smart guy like you, with 4 degrees, two of which are in engineering and in physics. His name is Daniel Hebert (French pronunciation). After viewing the prototype and the explanation behind it, he kept saying over and over, "You are going to win the Nobel Prize". I tell you this because I hope that I truly have your attention now. My government is useless in these matters. It has no infrastructure capable of assisting me to bring my Centrifugal Propeller to the point where it will be used in space. I hope that I have your attention and interest and that you will contact me to see what it is that I have done. Maybe you will understand the full implications of what I have done and want to incorporate this propulsion system into NASA's Mars and moon missions. Please do not dismiss me offhand. I have had very many critics tell me that what I have done goes against Newton's Third Law and therefore is not possible. They say that,,, until they actually see the prototype and my explanation behind its principle. I can be reached at Jeff Pluim at hot mail dot com. I hope that I hear from you.

*Thank You So Much* 😊❤ This is so encouraging: after decades of doing systems engineering & architecture as part of my very successful software and hardware engineering efforts, in the last couple years I have been easing into systems engineering officially. YET as an autodidact, I know there are many holes in my knowlege and experience, BUT it is most validating that I have all these important characteristics in spades!! Now I am filling-in the process pieces in formal ways that I never needed (nor was exposed to) in my smaller efforts in private industry. Talks like this give me context, validation, and encouragment as I move forward. 😊
