Modeling and the TOTE Model

What is the TOTE Model?

Trigger/Test
Decide when to run the Strategy

Operate
Do something, either internally such as make a picture in our mind, or in the outside world

Test
Compare the current state with the desired state

Exit
If the current state matches the desired state, stop, otherwise return to ‘operate’

This is the basic model for running a strategy, where a strategy is a method of achieving some outcome.

In Modeling, we seek to replicate the skill that a person has in achieving some outcome, so the TOTE model forms the fundamental basis of Modeling.

Multiple TOTES
In order to achieve a particular outcome, it may only be necessary to do one simple task, in a very small period of time. Think about bowling for example. The bowler picks up the ball, takes her position, moves forward to the lane and releases the ball. The skill is in doing that one pattern very consistently.

Other skills require multiple actions over extended periods of time. Think about painting a picture. It demands that we pick a medium and materials, a subject, sketch rafts, perhaps prepare and select specific materials for each element of the composition, then actually prepare the work possibly over many hours and days, reviewing and making modifications as we go.

For this reason the TOTE model can be overly simplistic. One way to add sophistication to the TOTE model is to treat a skill as a series of short self contained actions, so for example bowling may be described as one, two or three TOTES, whereas painting a picture may be dozens or hundreds of separate TOTEs.
