Principle eleven: A mathematical and statistical model is generally much less expensive than a market trial. Eco-technicians toolkit: Power law describe a circumstance when one quantity can be expressed as a power of another quantity (motion of planets to sun, behavior of consumers to wealth); fractals are the expression of power laws. Patching meets a constraint within a larger perspective requirement. Patching may not yield the optimal solution to a problem, breaking the problem into medium-sized nonoverlapping patches with no individual conflicting constraints enables the solutions in each patch to be optimized. Cellar Automata simulate cell behavior over time. Effective Eco-techs identify patterns and construct models and scenarious; surface networks, connections, and ecologies; recognize boundaries, inflows and outflows, and feedback systems; determine factors, parameters, leverage points for maintaining bounded instability; and provide quantitative training, tools and coaching to leaders and catalyst. "In order to be effective, eco-techs should be palced at the highest levels of the organization." Eco-techs are best at modeling macro processes.[Learn More ...]
