Informational Scarcity

Discipline of Relevant Data

Definition

Informational Scarcity is the ability of a data model to display only the necessary, meaningful, and actionable information, avoiding excess metrics, dimensions, and details that dilute understanding and erode decision-making.

A model that respects informational scarcity does not hide information,
but it does not expose it without purpose.

In Power BI, this property ensures that users receive the minimum amount of data required to understand a situation, without noise or redundancy.

Nature

Cognitive, semantic, and methodological.

Informational scarcity is not a technical limitation,
but a conscious design decision oriented toward the user’s mental clarity.

It emerges when:

Function

To protect users from analytical noise and cognitive fatigue.

In practice, this property enables:

Consequence

A model without informational scarcity informs a lot,
but explains very little.

Signals of Informational Scarcity

Signals of Informational Excess

This is not informational richness: it is structured noise.

Conceptual Example in Power BI

Informational excess (❌)

Result:
👉 the user does not know where to look.

Informational scarcity applied (✅)

Result:
👉 the user understands and decides.

Informational Scarcity and Model Design

Informational scarcity is reinforced when:

It is not just a visual issue:
it is a property of the entire model.

Interactions

Without informational scarcity, the other properties lose impact.

Samples

🔹 Sample 1 — KPI Hierarchy (Core vs Derived)

Problem (excess ❌)
A dashboard shows:

👉 The user does not know which one matters.

Scarcity applied (✅)

Core KPIs (visible):

Derived KPIs (on demand):

📌 Result:
The page communicates status and trend in seconds.


🔹 Sample 2 — Action threshold metrics

Informational excess (❌)
Irrelevant variations are shown (±0.3%, ±0.5%).

Scarcity applied (✅)
Metrics are shown only when they exceed an action threshold.

Sales Change (Actionable) := VAR Change = [Sales Growth %] RETURN IF( ABS(Change) >= 0.05, Change )

📌 Result:
The dashboard speaks only when action is required.


🔹 Sample 3 — Dimensions visible only when they add context

Excess (❌)
Default visible slicers:

Scarcity (✅)

📌 Result:
Fewer visible options → less cognitive friction.


🔹 Sample 4 — Metric separation by intent

Strategic metrics

Operational metrics

Exploratory metrics

👉 Only strategic metrics live on the main page.

📌 Result:
Each page responds to a distinct cognitive intent.


🔹 Sample 5 — Drill as a scarcity mechanism

Excess (❌)
All details visible on the same page.

Scarcity applied (✅)

📌 Result:
The user chooses to go deeper; they are not forced.


🔹 Sample 6 — Antipattern vs Pattern (Informational Scarcity)

❌ Antipattern — Exhaustive dashboard

✅ Pattern — Scarce dashboard

📌 Rule of thumb:
If the user needs more than 10 seconds to understand the page, informational scarcity is missing.

Synthesis

More data does not generate more knowledge.
More clarity does.
