The TIMN Model describes different ways of teaching:

• T for Tribe_the campfire
• I for Institutions_the lecture
• M for Markets_the debate
• N for Networks_the conversation

Societies, within this framework, began with tribal structures (99.9% of our history as human beings was spent in tribal structures) and expanded into institutional structures (nation-state bureaucracies) and finally into markets. Previous forms weren’t abandoned, instead, they were enhanced by the addition of a new form.  David Ronfeldt, the global guerrilla guru who came up with the acronym, argues that the tri-form structure of tribes, institutions and markets are now nearly universal.
