Start here:
Enterprise Architect
Focus on governance, portfolio steering, and structural coherence across multiple domains.
Level 1: Foundations
Requisite Variety
Ashby's Law of Requisite Variety says that only variety can absorb variety. To control a complex system, the control system needs at least as many response options as the system it is trying to govern.
Policy Resistance
Complex systems often contain a built-in defensive force that counters and blocks even well-intended solution attempts.
Purpose and Function
Every system has an objective purpose or function that can be read from its actual behavior, not from its official slogan.
Open and Closed Systems
Closed systems decouple from their environment, while open systems exist in constant exchange of energy and information.
Top-Down vs. Bottom-Up Architecture
Navigating between hard centralized top-down architecture guidelines and the local bottom-up evolution of teams.
Level 2: Practitioner
Governance Thawing
Rigid top-down governance cannot keep up with the speed of decentralized development, leading to chaos or standstill.
Tragedy of the Commons
The ruthless, locally rational self-interest of all parties destroys a shared architectural good for everyone.
Success to the Successful
Competition for limited resources radically favors teams with a slight head start while others are left to dry out.
Drifting Goals
Teams quietly adapt their standards to poor system behavior instead of improving the behavior. Quality dies a slow death.
Viable System Model
A masterpiece of organizational cybernetics that describes the mathematical and fractal structure every software company needs in order to stay alive under intense market pressure.
Boundary Critique
A method for exposing brutal blind spots by questioning what, and who, was actively excluded from an architecture decision.
Level 3: Strategic depth
Governance Feedback Cadence
The orchestration of the company's heartbeat by adjusting how often and how quickly IT leadership reviews architectural signals and reacts.
Incentive Redesign
The destruction of the cobra effect in IT by stopping the reward of failure-producing behavior and aligning incentives with system health instead.
Structural Coupling Adjustment
The surgical separation or reconnection of teams and systems to dissolve tight coupling and radically increase the innovation speed of individual squads.
Knowledge Graph Tooling
The organization's external brain. Graph-based databases and notes that connect code, architecture decisions, and people in one searchable network.
Dependency Graph Analysis
Cartography for architectural minefields. Tools that prove mechanically that a tiny change in "Frontend B" can somehow blow up "Backend Z.
