What’s your Minimum Viable Product?

November 4, 2015


I think this is a really brilliant graphic, it really gets you thinking – which route am I (perhaps unintentionally) taking? Pity about the awful name though, Minimum Viable Product.

It applies to developing ideas and plans of course, not just commercial products.

Ask the Chauffeur

October 28, 2015

A fun story spotted in The Telegraph and reproduced here:

One of the most important figures in quantum mechanics was the German physicist Max Planck. After he won the Nobel Prize for physics in 1918, he undertook a lecture tour of Germany.

“Naturally enough the lectures he delivered to the various audiences were more or less identical, a fact that was noticed in due course by his chauffeur.

One day the driver said to him: “Professor Planck, I’ve heard you give the same lecture on quantum mechanics so many times that I now know it by heart. It must be very boring for you, so for tonight why don’t we swap roles? I’ll deliver the lecture and you sit in the audience and wear my chauffeur’s cap.”

Planck agreed and that evening the driver got up on stage and delivered the lecture flawlessly. Then a member of the audience stood up and asked an incomprehensible question about quantum mechanics. Without hesitation the chauffeur said: “I’m surprised that someone from the renowned city of Munich could ask such a basic question. I will leave my chauffeur to answer it.”

Charlie Munger, Warren Buffett’s business partner, often tells this story. He uses it to illustrate the difference between real understanding of a subject – “Planck knowledge” – and the mere appearance of it, or “chauffeur knowledge”.

The “chauffeurs” of this world often distract attention from their shortcomings by putting on a great show. They may have a commanding presence, a way with words, huge self-confidence. In every walk of life – politics, business and, yes, journalism – you get both types of knowledge.

And of course you get both in fund management. Almost all fund managers can persuade you that they are a suitable person to entrust your life savings to. Sadly, the facts show many aren’t up to the task.

Choosing the right fund manager is one of the most important financial decisions we’ll ever make. Being able to distinguish those with chauffeur knowledge from those with Planck knowledge would be a huge help.

How can you tell them apart? Here are a few suggestions.

  • First, can they explain what they are doing in simple language? It’s the chauffeurs who seek refuge in jargon and obfuscation.
  • Second, do they ever admit that they don’t know the answer to a question? It’s the Plancks who have the self-confidence to admit ignorance when the circumstances call for it.
  • And the third, related test is whether they are aware of their own “circle of competence” and avoid being tempted to invest in areas that they are not properly familiar with.

Finding the right fund manager is hard. Fortunately, though, probably not as hard as quantum mechanics.”

You can of course replace fund manager with any other sort of manager! I appreciate that in practical situations admitting ignorance may easily be viewed as a weakness. I guess it works provided that you have the opportunity to clearly demonstrate your strengths so that people can get a rounded and balanced picture.

There’s an interesting discussion of chauffeur knowledge by Tim O’Reilly who points out that:

The point of the story was that there are two types of knowledge, the kind of rote knowledge that the chauffeur had, and the deep knowledge that Planck had. (What Munger didn’t say: the chauffeur had some Planck knowledge of his own, being clever enough to turn that question around! But it’s a great punch line — and a great concept.)

Courage And Confidence

October 10, 2015

I had a meeting with a friend yesterday where we discussed the key ingredients for successfully developing new ideas/startups etc. In particular, the differing roles that emotions and logical thinking play in making decisions that stick.

This brought to mind a recent post by Ed Batista on the difference between confidence and courage:

We may utterly lack confidence–we may even suspect that failure is a near-certainty. But that determination has no bearing at all on our ability to be courageous in the face of those long odds. The issue isn’t the likelihood of failure–the issue is the relative cost.

The key to untangling this confusion lies in understanding these two qualities and how they differ: Confidence is a calculation of the odds of success. Courage is a calculation that the cost of not trying is higher than the cost of failing.

Spotted in The Independent today (which incidentally has a much needed refresh of it’s website):

“Politics is the gentle art of getting votes from the poor and campaign funds from the rich by promising to protect each from the other” – Oscar Ameringer

If, like me, you’ve never heard of him, there’s an interesting description here:

But above all, Ameringer was funnyLife and Deeds of Uncle Sam: A little History for Big Children (1909) sold over half a million copies, and his autobiography, If You Don’t Weaken (1940) is a joy to read.  It’s available on Google Books here.  His views on politics are thoughtful, cynical, gentle and astute, and he doesn’t take himself too seriously.

Thought Experiments And Thinking Differently

July 7, 2015

The following thought experiment is attributed to the German Gestalt psychologist Karl Dunker:

One morning, exactly at sunrise, a Buddhist monk began to climb a tall mountain. The narrow path, no more than a foot or two wide, spiraled around the mountain to a glittering temple at the summit. The monk ascended the path at a varying rate of speed, stopping many times along the way to rest and to eat the dried fruit he carried with him. He reached the temple shortly before sunset. After several days of fasting and meditation, he began his journey back along the same path, starting at sunrise and again walking at a varying speed with many stops along the way. His average speed descending was, of course, greater than his average climbing speed. Is there a spot along the path that the monk will occupy on both trips at precisely the same time of day?

Here’s the way to approach thinking about it:

If you try to logically reason this out or use a mathematical approach, you will conclude that it is unlikely for the monk to find himself on the same spot at the same time of day on two different occasions. Instead, visualize the monk walking up the hill, and at the same time imagine the same monk walking down the hill. The two figures must meet at some point in time regardless of their walking speed  or how often they stop. Whether the monk descends in two days or three days makes no difference; it all comes out to the same thing.

As always, it’s easy when you know how!

Applying this to business (or other) problems, the point is to try thinking about the issue from a variety of quite different viewpoints even though that may initially seem quite alien, strange or unproductive.

This situation reminded me of the time when I was an academic and one year there was quite a fuss over a (physics) exam question that had been set. You could work it out from first principles and it would have taken about 30 mins for an average student. This assumes no slips were made along the way (and the greater the number of steps the more likely that this is to happen).

However, by using a conservation principle, you could also work out the answer in about 5 mins! To do this this you needed to think a bit differently right from the start and not get trapped into immediately using the standard approach. Even though some spotted this, as the question was so ‘easy’ using this insight, they were then worried that they were misunderstanding the original question!

As you can imagine, this resulted in a lively discussion of what constituted a ‘fair’ exam question. In practice, it’s helpful to know how to do it both ways of course, as one often elucidates the other.

Imagination And Knowledge

June 23, 2015

An interesting and vivid analogy on the role of imagination in coming up with new ideas and approaches, from the blog of Michael Michalko:

Suppose you are watching a mime impersonating a man taking his dog out for a walk. The mime’s arm is outstretched as though holding the dog’s leash. As the mime’s arm is jerked back and forth, you “see” the dog straining at the leash to sniff this or that. The dog and the leash become the most real part of the scene, even though there is no dog or leash.

In the same way, when you make connections between your subject and something that is totally unrelated, your imagination fills in the gaps to create new ideas. It is this willingness to use your imagination to fill in the gaps that produces the unpredictable idea.

This is why Einstein claimed that imagination is more important than knowledge.
