Gad is one of the professors at Kellogg that is a little full of himself- perhaps, most all of the Ops Management profs are. I anticipated some application of Little's Law or other Ops formula, instead of merely begging the question. While the pandemic has made us more aware of the possibility of better/safer retail models, self-checkout is definitely a step in the better/safer direction.

I'll take this as a compliment. I wish I could use Little's Law in this case, but alas, just an ordinary analysis.

To the point: I think self checkouts can be a step in the right direction, if used them solely rather than having a choice between them and humans (you can read more in the post). I do think however that there are much better options from Amazon Go to dark stores, etc.

I am now curious if you were in fact a student in my class, in which case, at least say hello. Moved to Wharton, BTW.

In fact, I was in your core Ops Management course, but I dropped it & completed the requirement with another instructor. I hope you’re enjoying Phillie; I’m still in Chicago. BTW, I really enjoy your blog posts!

Thanks!

The better/safer option?

Perhaps. It's hard to know what the future holds. But I hate self-checkout in today's grocery stores. It's frustrating, annoying, and doesn't improve anything for me as a shopper.

Given how much they are used, the market disagrees with your preference
