BPM: Tasklist Wooden Blocks

A few years ago, I was invited to visit the air traffic control tower at one of the international airports.
Screens, computers, lots of bleeping, great fun..
One of the things that caught my eye was the way the air traffic controllers manage aircraft take-offs.

A computer would print each of the plane’s flight-plan information on a small strip of paper.
The controller would take the strip and slide it onto a small wooden block (the size of a small ruler).
The controller had around 10 blocks in a queue in front of him.
He could, if needed, quickly change the order of take-offs by swapping the order of the blocks.
As each plane took off, he would remove the paper details from the block, move the block to the back of the queue and stick a strip on the block.

Although everything was computerized, this manual override procedure gave them the flexibility to run the operation smoothly, while staying within the policy and safety boundaries.

I have used many task-lists in the past, but never found one as simple as the wooden blocks method.
Employee’s task-list are usually ordered by date and priority. You never have the flexibility to adjust the tasks to fit ad-hoc prioritisation.

Wouldn’t it be great to have task-list wooden blocks?
