Tectology

Origin. Alexander Bogdanov, "Tectology: Universal Organizational Science" (1913-1922); pre-dates and anticipates general systems theory.

Mechanism. All systems—physical, biological, social, cognitive—are organized complexes of elements, and the organizational patterns recur across domains. Bogdanov identified three universal processes: conjunction (combination increasing organization), disjunction (separation decreasing organization), and selection (differential persistence of organized forms). A system's stability depends on its weakest link; a chain's strength is not the sum of its links but the minimum. Structural stability is explained by regulatory mechanisms (positive and negative feedback), not by equilibrium.

Procedure. Describe the system as elements and relations. Identify the organizational pattern: is it chain-like (serial, weakest-link), parallel (redundant, strongest-element), or feedback (cyclic, self-regulating)? For chain structures, strengthen the weakest link only; strengthening elsewhere has zero marginal effect. For parallel structures, add redundancy where failure is costly. For feedback structures, check the loop polarity: negative feedback stabilizes, positive feedback destabilizes. Does the system have both, and if so, which dominates?

Applies to. Capacity planning, resilience engineering, organizational diagnosis, and any problem involving system stability or fragility.

Limitations. Bogdanov's formalization is pre-mathematical and his examples are often strained analogies. The structural patterns he identified are real, but the claim that tectology is universal organizational science overclaims. Use for pattern recognition and structural diagnosis, not as a predictive theory. The weakest-link principle applies to serial systems only; inappropriately applied to parallel or feedback systems it misdirects effort.
