Teaching at IIMB: Mid-term review

IIMB has a strange policy. They are not allowed to have classes tomorrow on account of it being a national holiday so they shifted tomorrow’s concept to today, indicating a complete lack of appreciation of the concept of the long weekend. Anyway, since I didn’t have any other plans for the day or the weekend I decided to not request for a slot change and went anyways. This was my eleventh class out of twenty.

I expected the attendance to be rather thin today, but the class surprised me with more than three-fourths of the registered students turning up (on par with most sessions so far). And despite the class being at 8 am in the morning, none of them slept (at least I didn’t notice anyone sleeping). That is again on par with the course so far – more than halfway though the course and I’m yet to catch a single person sleeping in class! Maybe I should take some credit for that.

The class before today’s was about ten days back (long gap due to mid-term exams), and that day I had a minor scare. I had formulated a case that involved solving the Newsboy Problem (now politically corrected to “Newsvendor model“) as a sub-step in the solution to the case. Having worked out the sketches of the case solution the previous night I went to sleep hoping to work out the full case before I went to class. And my brain froze.

So it was 6:30 on the morning of an 8am class and I wasn’t getting the head or tail of the newsboy problem despite having known it fairly well. Decided to have cereal at home rather than go to SN to give myself more time to read up and understand the model. And my brain refused to open up. Yet I made my way to class, hoping I could “wing it”.

I didn’t have to, for the class exceeded expectations and solved the case for me. One guy popped up with “newsvendor model”. Another guy said that we could consider a certain thing as a “spot price”, thus eliminating the need to make any assumptions on costs. Then we started working out the model on Excel (remember that this is a “spreadsheet modelling” course). And the time came to implement the newsvendor model. And my brain froze in anticipation. “How do we do this?”, I asked, trying to not give away my brain freeze.

“We calculate the critical ratio”, came the chorus (sometimes I dispense with the politeness and order of people raising their hands and speaking in order). “And what is that here?”, I asked. “B6/(B5+B6)” came back the chorus. And then when I asked them how to impute the ordering level based on this, the chorus had figured out the exact way in which we should use NormInv to determine this. The troubling bit of the newsvendor problem having been thus solved, I took control and went forward with the rest of the case. And my respect for the class went up significantly that day.

Later in the day I was relating the incident to the wife, who I might have mentioned is an MBA student at IESE Business School in Barcelona. “Oh my god, your class is so quant”, she exclaimed. This is a topic for another day but perhaps due to the nature of the admissions procedure, students at IIMs are definitely much much more quantitatively oriented than students at B-schools elsewhere. Yet, IIMs don’t seem to be doing much in terms of harnessing this quant potential which should be giving their students a global competitive advantage.

And coming back to my class, they’ll be sitting for placements starting the 9th of February. If my class is a representative sample (it is most likely not, since I’m teaching an elective and these people expressed interest in learning what I’m teaching, so there is a definite bias), this seems like a great batch at IIMB. So I encourage you to go and recruit!
