README

Excerpt

Effectuation

Under Knightian uncertainty, start from available means and affordable loss—not a fixed goal and predicted return. Create the path through controllable action and real commitments.

When to Use

The market, technology, or problem is novel enough that outcome probabilities are not trustworthy.
Means are clearer than the goal: identity, skills, assets, and network exist before a fixed target does.
A small action can buy information or a partner commitment without risking ruin.
Plans keep breaking because the environment shifts faster than forecasts.

When NOT to Use

This is the opening of the README. Read the full README on GitHub.
