Finally, many months after other Indian states had conducted a similar exercise, Karnataka released the results of its first “covid-19 sero survey” earlier this week. The headline number being put out is that about 27% of the state has already suffered from the infection, and has antibodies to show for it. From the press release:…
Tests per positive case
I seem to be becoming a sort of “testing expert”, though the so-called “testing mafia” (ok I only called them that) may disagree. Nothing external happened since the last time I wrote about this topic, but here is more “expertise” from my end. As some of you might be aware, I’ve now created a script…
Simulating Covid-19 Scenarios
I must warn that this is a super long post. Also I wonder if I should put this on medium in order to get more footage. Most models of disease spread use what is known as a “SIR” framework. This Numberphile video gives a good primer into this framework. The problem with the framework is…
The future of work, and cities
Ok this is the sort of speculative predictive post that I don’t usually indulge in. However, I think my blog is at the right level of obscurity that makes it conducive for making speculative predictions. It is not popular enough that enough people will remember this prediction in case this doesn’t come through. And it’s…
Dam capacity
In Mint, Narayan Ramachandran has a nice op-ed on the issue of dam capacity and damn management in the wake of the floods in Kerala last year. In that, he writes: For dams to do their jobs in extreme situations, they should have large unfilled capacity in their reservoirs when extreme events occur Reading this…
Generalist and specialist managers
A really long time ago, I’d written this blog post about “comparative advantage” versus “competitive advantage” employees. A competitive advantage employee is better at a particular kind of task or skill compared to the rest of the team, and he is valued for that kind of skill. A comparative advantage employee, on the other hand,…
Axes of diversity
Companies and educational institutions, especially those that have a global footprint and a reputation to protect, make a big deal about diversity policies. It is almost impossible to sit through a recruitment or admissions talk by one such entity without a mention to their diversity policies, which they are proud of. And they have good…
Meeting types
There are essentially three kinds of meetings – those that are entirely “in person”, those that are entirely “on call” and hybrids. I argue that the quality of conversation in the third kind of meeting is significantly inferior to that of the first two types. In person meetings are those where all participants are in…
Planning and drawing
Fifteen years ago I had a chemistry teacher called Jayanthi Swaminathan. By all accounts, she was an excellent teachers, and easily one of the best teachers in the school where she taught me. Unfortunately I don’t remember much of what she taught me, the only thing I remember being her constant refrain to “plan and…
Law of conservation of talent
For starters. there is no such law. However, there exists a belief in most people’s minds that everyone is equally talented, and it is only that talent in different people is spread across different dimensions. It starts when you are in school. If you are not good at maths, people tell you that you must…
Duckworth Lewis and Sprinting a Marathon
How would you like it if you were running a marathon and someone were to set you targets for every 100 meters? “Run the first 100m in 25 seconds. The second in 24 seconds” and so on? It is very likely that you would hate the idea. You would argue that the idea of the…
Numbers and management
I learnt Opeations Research thrice. The first was when I had just finished school and was about to go to IIT. My father had just started on a part-time MBA, and his method of making sure he had learnt something properly was to try and teach it to me. And so, using some old textbook…
Levers and Pulleys
I’m writing this based on my insights as a management consultant. Apologies in advance if I end up on a global or gyaan-spouting trip One of the most common ways of ending up in corporate paralysis is to split up a particular target into constituent “levers” and hand over the management of each of these…
Generalists and specialists
So you have generalists and specialists. Generalists are fundamentally smart people who can do a variety of things. They take a look at a problem, take some time to understand the basics, and then go about solving it. They get bored easily, and move from problem to problem. Generally, they don’t dig deep but are…
The Quants
Since investment bank bashing seems to be in fashion nowadays, let me add my two naya paise to the fire. I exited a large investment bank in September 2011, after having worked for a little over two years there. I used to work as a quant, spending most of my time building pricing and execution…
On mental math and consulting careers
Sometime last week, the wife wanted to know more about management consulting, and I was trying to explain to her the kind of work that consulting firms do. I told her that the two most important skills to have in order to be a successful consultant are structured thinking and people skills, and in order…
Big Management and Big Picture
One common shortcoming that top management in a lot of companies is accused of is that they give too much attention to details (i.e. sometimes they micromanage), and they are unable to see the big picture. For example, if you think about the financial crisis of 2007-08, people kept making stupid bets about the mortgage…
Handling Jesus
A few months back, perhaps during the football world cup, I had talked about the role of Jesus Navas in the Spanish attack. He would mostly be brought on as a “plan B”, mostly when the Spanish tiki-taka failed to break down the opposition defence. And by hogging the right touchline, he would single-handedly offer…
The Trouble With Analyst Reports
The only time I watch CNBC is in the morning when I’m at the gym. For reasons not known to me, my floor in office lacks televisions (every other floor has them) and the last thing I want to do when I’m home is to watch TV, that too a business channel, hence the reservation…
Successful IPOs
Check out this article in the Wall Street Journal. Read the headline. Does this sound right to you? MakeMyTrip Opens Up 57% Post-IPO; May Be Year’s Best Deal It doesn’t, to me. How in the world is the IPO successful if it has opened 57% higher in the first hour (it ended the first day…
Independence and contribution at work
This is based on a discussion I had at work a few days ago. We were talking about people being able to do things out of their own initiative, come up with their own new ideas, inventing their own problems to work on (which would be useful for the firm on the whole) and stuff.…
