Thinking lazily about problem-solving methods

A little while ago I saw this somewhat unusual list of words:

It appeared on the xkcd blag, and Randall shared very little about it: It was in his handwriting, it looked faintly familiar, and he had no idea what it was about. You can see the whole story here.

I whiled away some time just thinking about how I would go about solving it.

That took me back a while, letting me reminisce about problem-solving techniques in general, how I learnt about them, what I found enjoyable about that learning.

For example, I still remember the first time I was presented with the “n” players in a knockout tournament, no ties, how many matches in the tournament question. n was set at 128; some people were doing the traditional 64+32+16+..+ thing, the rest of us had listened to the teacher. He very pointedly said “Think. How many losers?”. And we were ecstatic children, discovering for ourselves the truth that each match produced precisely one loser, and that the tournament needed 127 people to lose….

And so I thought to myself, of all the problems I’d seen where there was a lesson in problem-solving to be learnt, which one had I enjoyed the most?

I decided my personal winner was this one, presented to me in two parts:

(a) There is one, and only one, ten-term arithmetical progression of primes between 1 and 3000. Find it.

(b) Prove that no arithmetical progression of primes, containing eleven or more terms, can possibly exist between 1 and 20000.

I may have got the precise wording wrong, but the salient numbers are correct. See what you think. And if you have similar examples, where you learnt a simple problem-solving technique that stayed with you for the rest of your life, then please do share it.

[Incidentally, I still have no idea what Randall’s list is about. I used a progressive google search approach on the words (where you add one search term at a time and see how the top results behave) and the best I could come up with was “words at the top of successive pages in Animal Farm“. But it feels lame and unworthy. I quite liked one of the suggested answers, that the words were a sequence of captcha words. When I last looked not even Randall had figured it out.]

If you haven’t seen it yet…

…it’s worth checking out stackoverflow, and its associated blog.

A collaboration between Joel Spolsky and Jeff Atwood, both of whom I’ve followed for a while. I’ve listened to the podcasts, followed the blog posts, and so far I haven’t been disappointed. Worth the while. In fact I even like the logo.

Musing about Ebbsfleet….and Obama

….and Torquay.

Today’s headline: Ebbsfleet 1 Torquay 0.

And so Ebbsfleet win the FA Trophy.

Not bad for a club that was “taken over” by around 27,000 members, each of whom paid £35.

Here’s an extract from the Wikipedia article on the club:

On November 13, 2007, it was announced that the website MyFootballClub had entered a deal in principle to take over the club.[6] Approximately 27,000 MyFootballClub members each paid £35 to provide an approximate £700,000 takeover fund and all own an equal share in the club but make no profit nor receive a dividend. Members have a vote on transfers as well as player selection and all major decisions. Because of the nature of MyFootballClub, it was announced that manager Liam Daish would become instead the first team Head Coach. His backroom staff would remain at the club.[6]

Between January 16 and January 23 2008, MyFootballClub members were given the choice to vote on whether to proceed with the takeover and whether to allow Liam Daish to continue with his plans for the January transfer window. Both resulted in overwhelming “Yes” votes: 95.89% voted to proceed with the takeover while 95.86% voted to allow Daish to continue his transfer plans. The deal was ratified at an Extraordinary General Meeting of the club’s board on 19 February.

Collaborative ownership, collaborative management, championship trophies. Hmmm.

Now consider Barack Obama. The millions of dollars of campaign money generated by thousands of people paying small sums of money. What if his fans had the same power as Ebbsfleet fans (or, more correctly, MyFootballClub fans)?

Just thinking. Ebbsfleet is the shape of things to come. In more ways than one.

Thinking about collaboration

There is something in me that makes me pretty relaxed about “sharing” per se. Maybe it was caused by growing up in a large “undivided” family: when I lived in India, the class of family I was part of was referred to as a Hindu Undivided Family or HUF. This was seen as distinct and different from other families where formal division had been applied for, ostensibly to take advantage of tax advantages that accrued as a result.

Or maybe it was because I grew up in Calcutta. Access to material goods seemed a lot more important than ownership of the same goods; possession was a transient concept. It wasn’t your bed, your book, your park bench, your air. You just had passing and temporary rights to it, and the rights would fade as easily as they came to exist.

Maybe it’s something in me, maybe I don’t like the sheer palaver. One way or the other, I have always found it easy to share.

Which is probably why I assumed that failures in collaboration were usually caused by people not having this facility: by people finding it hard to share. Sometimes this was caused by insecurity, sometimes it was cultural. At least that’s what I assumed.

More recently, as I’ve been continuing with my investigations into intellectual property law, patents, copyrights, trademarks and their burgeoning digital equivalents, I’ve begun to wonder about something else.

And it is this. When you look at the Agricultural Revolution you notice something. Scale happened when the participants understood division of labour. When you look at the Industrial Revolution, something similar happened. Ford and Taylor could not construct an assembly line unless there was something to make a line with. Division of labour again.

Collaboration takes place when you do what you are good at, and when you let other people do what they are good at.

Sometimes I wonder whether we as knowledge workers have learnt this. Somehow I don’t think so. Over the last thirty years, working primarily in service industries, working solely as a knowledge worker, I see something different.

I see people unable to respect the skills of others. Of wanting to be all things to all men.

I see no division of labour within knowledge workers.

Which is a shame.

Collaboration has many payoffs. These payoffs tend to increase when there is a shortage of the “resource” being shared. We live in an age where the war for talent is likely to continue. Knowledge workers have the most to gain from collaboration.

But we’re not going to get there. Not while we limit ourselves, not while we try and pretend there is no division of labour.

Each of us has to learn to do what we are good at, and to let others do what they are good at. Even if we think we’re good at those things as well, we have to choose to do the things we are disproportionately better at. That’s not just a prerequisite for collaboration. That’s not just a prerequisite for teamwork. It’s a prerequisite for being a human being.

Collective stewardship requires respect for others. Respect for others requires respect for their skills and abilities. For some reason, we could handle it during the Agricultural Revolution, we could handle it during the Industrial Revolution, but when it comes to the Information Revolution, we’re falling short.

Views? Comments? That is, if you’re prepared to share them….

Musing about strategy

some questions i’m trying to deal with as i write strategy papers on a number of subjects:

  • if you tell everyone your strategy, is it still strategy?
  • if you don’t tell anyone your strategy, is it still strategy?
  • shouldn’t we use wikis to capture strategies?
  • can linus’s law be made to apply for strategy?
  • shouldn’t customers be involved?
  • and if we work in coopetitive markets, shouldn’t competitors be involved?

…….

and if all the answers go one way, then

does it mean that the distinctive value is in execution, not strategy per se?

just wondering.
