Appendix

This Appendix is positioned as supplementary to the understanding of the main text. The content shown here is not for making new claims or providing detailed explanations.

The Failure Patterns and decision-design concepts addressed in this site are not direct applications of specific methodologies or theories. On the other hand, they clearly connect with several lines of research and thought.

The Appendix presents those lineages as correspondence tables organized by concept. The purpose is not to assert legitimacy, but to quietly ensure that interpretation does not become arbitrary.

The main text stands on its own without reading the Appendix. It is assumed that reference is made to confirm background when necessary.

Conceptual Lineage

The following are the main axes of thinking that support this site as a whole. Each item is not an independent explanation, but structured as supplementary material to show correspondence with elements in the main text.

• Pattern Language
  The idea of treating "recurring situations" rather than problems as units.

• Responsibility & Decision
  The perspective of treating the location of responsibility, decision, and authority as a design target.

• Information Hiding & Boundaries
  Design principles for isolating boundaries, assumptions, and reasons for change.

• Feedback, Measurement & Learning
  A framework for establishing learning through feedback and measurement.

• Systems Thinking & Constraints
  A perspective for treating problems as whole system behavior rather than local optimization.

• Requirements & Knowledge
  The idea of handling requirements, specifications, and tacit knowledge from the perspective of decision-making capability.
