I went on a 6 months twitter detox. But Sunday's virtual #WhartonGrad celebration is a good time coming back. Congratulations to The Wharton School class of 2020. And congratulations and thank you to our dean Geoffrey Garrett for all the things he has done for the school.

As an ops-professor, really shocked to see how the richest country on earth is running out of $0.60 items of PPE. Had the privilege to work with my friend Kevin Volpp and a Penn The Wharton School Penn Medicine team to build some planning tool. Check out our OpEd tinyurl.com/y8r2z62y

The partisan divide over #COVID continues, and it's massive. 73% of #Republicans feel comfortable about returning to their regular (pre-COVID) routines; only 23% of #Democrats are comfortable.

Was always interested in the question of compensating resources for emergency capacity, even if capacity ends up idle. Covid-19 is a good case study. Take a look at piece with my Penn Penn Medicine friends Kevin Volpp and Kevin B. Mahoney in the NEJM : tinyurl.com/y974g8mu

Very honored to see that my paper with Hessam Bavafa on physician work hours has received the best paper award Journal of Operations Management at this year's Academy of Management. Thanks to all at Penn, The Wharton School, and Mack Institute that have supported us.

Honored to see that my book with The Wharton School friend and colleague Nicolaj @Siggelkow made it onto the Bloomberg’s best book list for 2020. Happy holidays and let’s stay connected in 2021 (using a #ConnectedStrategy). tinyurl.com/y396xc2o

Three months ago, I was thrilled to be one of the first receiving the Rivian R1T. What a great car! Today, the car sits de facto unusable in the driveway. What do you think happened? (Hint: I teach my The Wharton School MBA students to look for the bottleneck). Any guesses?

Why is my Rivian unusable three months after purchase. Got lots of great suggestions. Here is a hint from my The Wharton School and Coursera Ops course: the bottleneck in a process is not always where you think it is. Take a look at the following process flow diagram…

Interesting NYTimes article on productivity measurement tinyurl.com/yp33rn2s . In my latest KnowledgeatWharton article tinyurl.com/bdjcc8c6 I am more positive about such tools. It is just all about how you use it? What do you think?

Happy to see my new book with Karl T. Ulrich in print. Thanks for all the support from The Wharton School , Penn, Penn Medicine, and Wharton School Press . We are working on an audio book (and already have an MVP…:)

I had OpenAI Chat GPT3 take my The Wharton School Operations Management MBA exam. It got a B/B-. Is that good or bad news? Can we replicate this at other schools / subjects? Some implications are in this Mack Institute report tinyurl.com/2bxneu3n

Fast-reading and filled with real-world successes, #TheInnovationTournamentHandbook, by and Christian @Terwiesch and @KTUlrich is a comprehensive roadmap to finding a new match between a solution and a need that is not merely good, but exceptional. bit.ly/3hIfudx

“The most important step in innovation is not the innovation per se, but figuring out what challenge you’re addressing,” The Wharton School's Karl T. Ulrich on his book with Christian Terwiesch, #InnovationTournamentHandbook Knowledge at Wharton youtube.com/watch?v=aRZCD8…

How can we take advantage of the hallucinations of ChatGPT? Turn them into ideas for an innovation tournament! ft.com/content/591ad2…; check out the new book with Karl T. Ulrich on the importance of variance in innovation #InnovationTournamentHandbook

Exactly 30 years ago, I joined the INSEAD PhD program. Thank you to all faculty and fellow INSEAD Alumni for making this amazing experience happen. As I sit today in my The Wharton School office, my best wishes to all the incoming PhD students here and everywhere else in the world!

My new The Wharton School paper asks a simple question: Can AI-based ethical advice compete with a human expert? So, my Penn friend Lennart Meincke and I set up a race. The New York Times writer Kwame Anthony Appiah ("The Ethicist”) vs OpenAI GPT4. To see the results: tinyurl.com/9hfvt99c

Note a joke ... two Germans wrote this piece...:). Our The Wharton School paper asks: Can AI-based ethical advice compete with a human expert? So, Lennart Meincke and I set up a race. The New York Times writer Kwame Anthony Appiah ("The Ethicist”) vs OpenAI GPT4. The results: tinyurl.com/9hfvt99c

Is it ok for students to use #ChatGPT? Professor Christian Terwiesch tells the The Wall Street Journal one approach to combat misuse of the technology is to raise the bar for students, now that they have such a powerful tutor and research aide. whr.tn/3Szh2qy

Great article about the work my The Wharton School friends Gideon Nave and Lennart Meincke and I have been doing on ethical advice and AI: scientificamerican.com/article/ai-cha… . Thanks to the Mack Institute funding this!
