The Singular Method: Principled Systems Design

Insight: "Avoid over-abstraction by pivoting to study patterns." — The Architect

1. The Trap of "Universal Abstraction"

Engineers love to say "everything is an object." This leads to monolithic schemas (like AssetSchema) that try to be everything to everyone—tracking a Skyscraper with the same table used for a Leaf Blower.

The Symptom: A schema full of optional fields, conditional logic, and "schizophrenic" identity.

2. The Method

To avoid this trap, we follow this 4-step process:

Step 1: Identification (The Census)

List everything that must be accounted for.

Example: Buildings, Units, Cars, HVAC units, Cleaning Supplies, Keys, Contracts.

Step 2: Abstraction (The Grouper)

Group similar things to find the "Universal Class."

Example: "These are all Assets. They all have value and physical location."
Danger Zone: Most teams stop here. This creates the Monolith.

Step 3: The Pivot (Differentiation)

CRITICAL STEP. Ask: "How are these 'Like Things' effectively different in behavior and pattern?"

Property (Real Estate):
Pattern: Sits still. High value. Has Rights/Deeds. People live in it.
Lifecycle: Decades/Centuries.
Inventory (Equipment):
Pattern: Moves around. Depreciates. breaking/fixing. Staff use it.
Lifecycle: Months/Years.

The Lesson: Even if they share fields (Name, ID), their Behavioral Patterns are opposite. Therefore, they demand separate Domains.

Step 4: Pattern Recognition (The Design)

Find the minimum number of patterns to model the system without conflating behaviors.

Result: Two Domains (Property vs. Inventory) linked by a thin reference (Logic), rather than one Domain with thick logic (Spaghetti).

3. Application

When designing new features:

Don't just look at Data Shape (fields).
Look at Lifecycle Patterns (creation, usage, destruction).
If the Life Cycles diverge, Split the Domain.
