Evaporating Cloud
Purposedifferent
ARID examines how well developers can work with a technical design. It focuses on a part of the system that can still be revised, between the architecture overview and the detailed specification.The Theory of Constraints Thinking Process exposes a system's bottleneck and the logic behind it. It suits situations where many symptoms trace back to the same limiting relationship.A Causal Loop Diagram makes feedback, reinforcement, and balance in a system legible. It uncovers side effects and self-reinforcement that stay hidden in linear explanations.The method makes visible why two seemingly incompatible demands arise and which assumption must be tested to resolve the conflict.
