On Indians and projects

When asked what type of management education India needs, I often say, "Most importantly, we need to teach people how to run projects - how to break the work into significant tasks, how to assign responsibilities and set timelines, and how to report consistently on those timelines, mitigate risks etc. I don't want MBAs with bookish knowledge, I want someone who can really get stuff done. And much of it boils down to planning and executing projects."

And I have blogged about it here and here and elsewhere.

Well, this week I am in Europe, mortified as the news of the CommonWealth Games dominates newspapers and television channels here. It even comes up in business meetings.

All because of very shoddy planning. I really think that corruption is a somewhat separate issue.

Yet I also want to add this (if only to calm myself) - yes, China can put up taller buildings than India can, better buildings than India can, and can put them up in a planned way. But when it comes to software, Indian project planning is as good as you can get anywhere in the world. There are two Indias, and software is part of the new India...

The role of testing in education

Shri Kapil Sibal is moving towards making school education more "holistic" in India - an effort most of us agree with - but he is also moving to reduce drastically the number, type and intensity of tests.

Honestly, that scares me. Mindless testing is, well, mindless, but are we throwing out the baby with the bathwater? The positive global identity of India in recent times has been shaped by the tens of thousands of analytically strong Indians who, despite a crushing lack of exposure in their homeland (to technology, to processes, to reliable electricity and running water in their homes), are able to tackle, say, the IT problems of the world because they have the analytical skills to wrap their minds around them.

Interestingly, new research appears to underscore the importance of testing. In an article in the New York Times titled "Forget What You Know About Good Study Habits" (incidentally the most emailed article on that site for several days running), Benedict Carey describes some of these experiments. A portion of the article is reproduced below.


(C)ognitive scientists see testing itself — or practice tests and quizzes — as a powerful tool of learning, rather than merely assessment. The process of retrieving an idea is not like pulling a book from a shelf; it seems to fundamentally alter the way the information is subsequently stored, making it far more accessible in the future.


Dr. Roediger uses the analogy of the Heisenberg uncertainty principle in physics, which holds that the act of measuring a property of a particle alters that property: “Testing not only measures knowledge but changes it,” he says — and, happily, in the direction of more certainty, not less.
In one of his own experiments, Dr. Roediger and Jeffrey Karpicke, also of Washington University, had college students study science passages from a reading comprehension test, in short study periods. When students studied the same material twice, in back-to-back sessions, they did very well on a test given immediately afterward, then began to forget the material.
But if they studied the passage just once and did a practice test in the second session, they did very well on one test two days later, and another given a week later.
“Testing has such bad connotation; people think of standardized testing or teaching to the test,” Dr. Roediger said. “Maybe we need to call it something else, but this is one of the most powerful learning tools we have.”

Another article regarding the Chinese emphasis on testing can be found here. Chinese students are, perhaps consequently, extremely good at maths and analysis. The author, Elisabeth Rosenthal, quotes a Professor Cizek who specializes in educational measurement and evaluation:


“What’s best for kids is frequent testing, where even if they do badly, they can get help and improve and have the satisfaction of doing better,” he said. “Kids don’t get self-esteem by people just telling them they are wonderful.”



Testing in the Indian education system definitely needs to become more feedback oriented, rather than marks oriented. That said, I would rather that we in India not give up on the academic rigor that testing alone can bring. In my personal opinion, we should not destroy the existing framework unless we are sure we know what we are doing. Even the US is moving back towards more testing, somewhat regretting its rather relaxed approach in the past towards school education. In terms of academic rigor, I'd rather India continue to refine its own approach than follow the (old) US schooling model blindly.

By the way, one model I really admire is the German model for craftspeople. Having suffered at the hands of incompetent electricians, plumbers, carpenters and masons (among several other trades) and seen the supreme ability of their German counterparts, I can confidently say that India needs something like this desperately. No one will dispute that in this area, we can only improve. Why aren't we spending more time on this instead?

How to end a recession

Of late, there has been considerable debate - especially in the US and Europe - about government deficit spending to hit one's way out of a recession. A little like a side batting second in a one-day cricket match with few wickets left may choose to throw caution to the winds and go after the bowling, somewhat counter-intuitively.

Some left-leaning economists like Paul Krugman strongly advocate such spending, pointing out that Japan's tightening its purse-strings probably deepened that country's problems.

In fierce opposition, right-leaning economists point out that Germany has remained fiscally responsible and is doing well, while countries like Greece have had free-spending governments and have been the worst hit.

While reading yet one more article on this by Krugman in the NY Times, a thought dawned on me and I posted a comment (which I hope Krugman read!)

It seems to me that recovery from a major slump is ideally built around a theme of some sort, that businesses and individuals can rally around. Perhaps the theme may or may not involve major deficit spending.

A world war, a historic decision by businesses and trade unions to be flexible*, an appeal to the national character, an astrological prediction of a bountiful year, even a world championship win in a popular sport - in different contexts and cultures these could all be themes that pull an economy out of recession.



*as in Germany

You can see this in India. A lot of the richer people believe India is shining, so it is not doing badly overall. Currently growth seems to be a seriously lagging indicator of the stockmarket indices, rather than the other way around.

In the US, people and businesses are currently pessimistic, so the situation is worse than it might have been. There are fundamental problems - primarily too little genuine education and too much soundbite TV - but these are not insurmountable.

Perhaps the US should have been allowed to win the soccer World Cup?

Dreamland: At the library

I was self-righteously upset. I went up to the librarian. "Ma'am, the books are not where they should be..." And then, "I admit once or twice I myself have put books back in slightly the wrong place ... but at least I have always felt guilty about it afterwards."

To my surprise she did not see my complaint as an accusation and said, "I totally agree. I can't tell you how important that is."

Taken off guard, I looked at her face, thin and drawn with horned black glasses. I wondered who she thoguht was responsible for the problem - wasn't it her responsibility? "We have such a beautiful library here otherwise. But if you can't find the books, all that money is wasted." And as I said it I saw how well lit and sunny and airy the library was. Airy, yes, that was the word. "All that money is wasted", I said. I was about to add "and there is then nothing left of it for everyone" but held back - it seemed somehow too money-minded and suddenly I thought as well, "I don't know what a librarian makes. Maybe she doesn't make much."

"No, I totally agree", she said, and then she walked ahead of me into the bookshelves to show me something. Her clothes were all white, but a white that was as though seen through a slight fog... a foggy white.

She stood at a bookshelf and said, "For example, this book here has been filed under both Airlines and Section 1.4.02". I marveled just a little at how amazing library systems were and I reached out and picked up a random book.

It was a photocopied book, and I opened it at random to find the chapter title, "Don Bosco School". It presumably was an alumni list. Must be Calcutta - that's the big Don Bosco. But I looked a little closer and it said "Ahmedabad". "This is the alumni directory", she said almost as I figured it out myself. "It also has the listing for Don Bosco Indore..."

>>>>>>>>>

That's just the transcript of a dream I had a few weeks ago and wrote down minutes after waking up from it when it started fraying. Dreaming is an incredible activity. Many dreams are more vividly experienced than real life itself is.

The stitching together of so many subjects breathlessly - in just a few seconds of perceived action - is also fascinating. The library (I haven't really spent time in a library for more than a decade), the photocopied books (something from our IIT days in the early 1990s), the reference to airlines (I take care of the Lufthansa account at Nagarro), the reference to Indore and Ahmedabad (the Proton locations), the reference to Don Bosco (where I went to school till 1989).

The dream plays out like a story created deliberately and rapidly by some devilish genius... At each step the slightest of cues are used to switch context.

Dreams must play some critical role. It is difficult to believe that they are just by-products of our mind. If they are meant to remind us of memories in order to refresh them, then they must be quite a sophisticated evolutionary achievement.

The vividness of the dream of course can also make you question the reality of perceived reality. The only fundamentally different thing about reality is that it follows more detailed laws that don't change.

For example, you wake up day after day to the same wife. :-)
