Why Great Architects Think Like Model Thinkers: Core Principles Explained

What Is Architecture?

ISO/IEC 42010 defines architecture as “the fundamental organization of a system, embodied in its components, their relationships to each other and the environment, and the principles governing its design and evolution.”

The three essential elements are:

Clearly defined modules or components

Explicit relationships between components

Constraints and guiding principles

These elements apply from a simple toy to a nation’s operation.

Software Architecture Example

Modules: models, domains

Relationships: one‑to‑one, one‑to‑many (models); dependencies (domains)

Principles: single responsibility, open‑closed, Liskov substitution, etc.

Organizational Architecture Example

Modules: departments

Relationships: management or reporting lines

Principles: management and financial principles

What Is an Architect?

An architect’s responsibilities are to identify and define problems, create, select, or adjust an architecture, and thus find the optimal solution.

The typical workflow is: define the problem → determine the architecture → propose a solution → implement and deliver results. The earlier steps are more abstract and more critical.

1. What Is a Problem?

In this context, a problem is a contradiction (as defined in Marxist philosophy). Any unresolved contradiction is a problem.

“Problem is the contradiction of things. Where there is an unresolved contradiction, there is a problem.” – Mao Zedong

2. Distinguishing Problem, Means, and Challenge

Problems, means, and challenges are all contradictions at different levels. A high‑level problem can be broken down into concrete means, which in turn reveal specific challenges.

3. Defining a Problem

“The significant problems we face cannot be solved at the same level of thinking we were at when we created them.” – Albert Einstein

Elevated thinking (identifying the underlying problem) leads to better solutions, such as moving from “faster horses” to “cars.”

What Is a Model?

A model is an abstraction of the real world that defines elements and their relationships, enabling logical deduction.

Compared with architecture, models focus on logical inference, while architecture emphasizes constraints and guiding principles.

Model Example: Improving Exam Scores

To raise the number of students scoring above 90, use a normal‑distribution model with two key variables: mean and variance. Increasing the mean yields a larger impact than increasing variance.

What Is a Model Thinker?

A model thinker, like an architect, faces problems, sees their essence, selects or builds an appropriate model, and derives the optimal solution.

Notable Models

Cognitive Pyramid : data → information → knowledge → wisdom; wisdom is the ability to select the right model for a problem.

Solow Economic Growth Model : O = output, A = technology, L = labor, s = savings rate, d = depreciation; shows that technology growth has a quadratic effect on output.

Other models include diffusion models, Markov models, etc.

Applications of Models

Information anxiety: focus on summarizing models rather than endless data.

Data analysis: transform raw data into information, then knowledge, then models for decision‑making.

Investment: use computational models to automate decisions, as described in Dalio’s “Principles.”

Conclusion

Architects and model thinkers share a similar methodology: when you can modify a system, use architectural thinking to define and solve problems; when you cannot change the system’s mechanics, adopt model‑thinking to understand its essence and find the optimal solution.
