Discontinuous Levels and Hierarchy

This is a series on Teal and Levels of Work. Here is the backstory for the series in case you are interested. The purpose for the series is to explore the tenets of Teal through the lens of Levels of Work. Links to each post in this series, below.
From the Ask Tom mailbag –

In your post yesterday, you said that growth (of capability) is nested in discontinuous levels and that these discontinuous levels were readily observable. What did you mean by discontinuous?

An electric car has a continuous power-train and no gears. It goes from minimum to maximum in one continuous power curve. Humans are more like a multi-speed transmission, where each gear winds out to its maximum, shifting into the next gear.

Jean Piaget was the pioneer who observed distinct stages in childhood development.
Non-verbal sensorimotor stage (birth to 2 years), where objects that cannot be sensed (seen or heard) do not exist. I have five fingers on each hand, but hands behind my back means I have no fingers at all.
Pre-operatonal stage (2-7 years) where symbolic language emerges to indicate relationships, though relationships are ego-centric, the child is the center of its universe.
Concrete operational stage (7-11 years), where the understanding of tangible concrete elements are organized, and abstract, conceptual elements are barely understood. Attention span (timespan) at age 6 increases from fifteen minutes to one hour at age nine.
Formal operational stage (11-18 years), where cause and effect logic, abstract conceptual elements are recognized and assimilated.

Elliott Jaques continued these observations of discontinuous stages throughout adulthood (age 20 through age 70).

  • Symbolic Declarative (S-I) – Timespan – 1 day to 3 months
  • Symbolic Cumulative (S-II) – Timespan – 3 months to 1 year
  • Symbolic Serial (S-III) – Timespan – 1 year to 2 years
  • Symbolic Parallel (S-IV) – Timespan – 2 years to 5 years
  • Conceptual Declarative (S-V) – Timespan – 5 years to 10 years
  • Conceptual Cumulative (S-VI) – Timespan – 10 years to 20 years
  • Conceptual Serial (S-VII) – Timespan – 20 years to 50 years
  • Conceptual Parallel (S-VIII) – Timespan – 50 years to 100 years

Cognitive development is not simply how many problems are solved within a time-frame. All problems are not created equal. Some problems are more complex than others, and that complexity is discontinuous.

For example –

  • Problem solving at S-I – Trial and error.
  • Problem solving at S-II – Cumulative diagnostics, comparative.
  • Problem solving at S-III – Root cause analysis, cause and effect, single critical path.
  • Problem solving at S-IV – Multi-system analysis, capacity, dependency, contingency, velocity.

Each of these stages in problem solving requires capability at that level. Levels of capability are observable and distinct, become the basis to understand levels of work. Levels of work define the framework for organizational hierarchy.
