Waguespack takes Christopher Alexanders's 15 fundamental properties of order and integrates them across system modeling ending up with:

3.1 Stepwise Refinement (To Elaborate)

3.2 Cohesion (To Factor)

3.3 Encapsulation (To Encapsulate)

3.4 Extensibility (To Render Extendable)

3.5 Modularization (To Modularize)

3.6 Correctness (To Align)

3.7 Transparency (To Expose)

3.8 Composition of Function (To Assemble)

3.9 Identity (To Identify)

3.10 Scale (To Focus)

3.11 User Friendliness (To Accommodate)

3.12 Patterns (To Pattern)

3.13 Programmability (To Generalize)

3.14 Reliability (To Normalize)

3.15 Elegance (To Coordinate)

He then combines those using some coherence metrics to end up with furuther properties that result in thriving systems:

5.5.1 Divisibility

- stepwise refinement and modularization

- supported by cohesion, encapsulation, correctness, and identity

5.5.2 Factorability

- cohesion and encapsulation

- supported by extensibility, transparency, identity, and scale

5.5.3 Constructibility

- composition of function and scale

- supported by identity, user friendliness, patterns, and elegance

5.5.4 Confidence

- correctness and user friendliness

- supported by cohesion, modularization, and correctness

5.5.5 Predictability

- patterns and reliability

- supported by correctness, transparency, and elegance
