The video of the kanban push-me pull-you presentation I gave at David Anderson's Lean Kanban UK conference is now up on youtube. Here's the slide-deck too.

Is an excellent book by Reginald D. Hughes (published 1924). As usual I'm going to quote from a few pages:

The great majority of fishermen are ignorant of the actual principles which underlie their every act, whether right or wrong.

One certain index of efficiency is the absence of effort. Style is synonymous with efficiency, and style and effort do not go together.

Double-handed fly casting may especially be recommended as almost, if not quite, the most beneficial form of exercise one can take. It calls for the use of every muscle in the body. It exercises without exhausting.

Excessive effort is not only uncalled for, but if practised defeats itself.

Brute force alone will never put one in the front rank.

A tight grip means tense muscles and joints throughout the body. It kills all attempts to cast smoothly and easily. It imparts, through a vibrating rod tip, waves and irregularities to the line, and is very tiring even to an onlooker.

Remember that the rod should be practically noiseless. Any distinct "whoosh" is a sign of a faulty casting, and shows that the cast is made with the entire rod instead of with the top.

Hold or grip of the rod - there should be none. The rod merely rests in the right hand, while the left hand lightly encircles the butt end. Any tendency to a tight grip must be resolutely suppressed.

Both hands must do an equal share of the work.

Our desire is to cast the fly across and downstream at an angle of about 45 degrees. So we stand, as regards our feet, facing this direction, and, without moving them, rotate the body until we face downstream, rod low and pointing in the direction of the fly.

In learning these casts try to avoid too much concentration, as the great secret is to let the whole body be free and swing easily and comfortably, letting the rod do it, and it will do it if the timing is right.

If the line is allowed to slacken in the least, even momentarily, the pull on it is lost.

is an excellent book by Peter Miller (isbn 978-0-00-738297-2). As usual I'm going to quote from a few pages:

As successful foragers return to the nest with seeds, they're met at the nest entrace by foragers waiting in reserve. This contact stimulates the inactive ants to go out. Foragers normally don't come back until they find something. So the faster the foragers return, the faster other ants go out, enabling the colony to tune its work force to the probability of finding food.

Instead of attempting to outsmart the desert environment, the ants, in a sense, were matching its complexity with their own.

Instead of trying to keep fine-tuning a system so it will work better and better, maybe what we really ought to be looking for is a rigourous way of saying, okay, that's good enough. [Deborah Gordon]

If a scout bee was impressed by another scout's dance, she might fly to the box being advertised and conduct her own inspection, which could last as long as an hour. But she would never blindly follow another scout's opinion by dancing for a site she hadn't visited.

J. Scott Turner considers the mound's function as a respiratory system so essential that the termites couldn't live without it. In a sense, he argues, the mound is almost a living part of the colony.

If individuals in a group are prompted to make small changes to a shared structure that inspires others to improve it even further, the structure becomes an active player in the creative process.

Unlike our systems, which are tuned for efficiency, the termites' systems have been tuned for robustness, which they demonstrate by building mounds that are constantly self-healing.

What really made the lights go on was the realization that termites don't pay attention to the environment itself but to changes in the environment.

Not only does this complicated structure represent an indirect collaboration among millions of individuals, it also embodies a kind of ongoing conversation between the colony and the world outside. The mound might look like a structure, but it's better thought of as a process.

We should think of it [the termite mound] as a dynamic system that balances forces both inside and outside its walls to create the right environment for the termites.

When you feel like you belong to something, it gives you so much more freedom and so much more energy that might otherwise be used up in anxiety, to do other things.

On January 12, 2006, several hundred thousand pilgrims had gathered in a dusty tent city at Mina, three miles east of Mecca...
By noon... about a half-million or more pilgrims filled the Jamarat plaza in front of the bridge... The pressure inside the crowd was crushing... More than an hour later, victims were piled up seven layers deep: 363 men and women were dead.
"Those in charge need to remember the root cause of the problem: too many people trying to get through too small a space. The ingress rate at the bridge was 135,000 per hour. The thoughput rate of the pillars was only 100,000 an hour. You can't put a pint into a half-pint jug." [Keith Still]
