The Default Decision Index (DDI)
A Simple Score Teams Can’t Game
The Default Decision Index exists to answer one question:
Are we becoming the assumed choice—yes or no?
It intentionally avoids vanity metrics, volume metrics, and self-reported confidence.
It measures behavioral evidence of default formation.
How the Index Works
- Scored quarterly
- Max score: 25
- Passing threshold: 15
- High confidence default: 20+
Each signal is binary or low-range to reduce gaming.
The Five Signals (5 Points Each)
1️⃣ Unprompted Reference Signal (0–5)
Score 1 point each time (cap at 5):
- Prospect references your ideas without being sent a link
- Your framing appears in inbound emails or decks
- Sales hears “we already align with this”
- Competitors indirectly respond to your POV
- External teams reuse your language
Why this can’t be gamed:
You can’t force people to borrow your language.
2️⃣ Decision Compression Signal (0–5)
Score 1 point each time (cap at 5):
- One less educational call is needed
- Evaluation steps are skipped
- Shortlists are smaller earlier
- Buyers move forward without new material
- Objections shift from “what is this?” to “timing / fit”
Why this can’t be gamed:
It shows up in sales behavior, not content output.
3️⃣ Internal Narrative Alignment Signal (0–5)
Score 1 point each time (cap at 5):
- Sales uses content language verbatim
- Product docs mirror organic framing
- Leadership repeats the same phrases externally
- New hires adopt the narrative quickly
- Teams stop re-explaining the basics differently
Why this can’t be gamed:
Misalignment is obvious immediately.
4️⃣ Core Asset Dependence Signal (0–5)
Score 1 point each time (cap at 5):
- A small number of pages are reused constantly
- Removing a core page would cause disruption
- Updates outperform new publishes
- Repeat engagement concentrates on few assets
- Teams protect these pages instinctively
Why this can’t be gamed:
Dependence emerges naturally—it can’t be faked at scale.
5️⃣ Search Behavior Shift Signal (0–5)
Score 1 point each time (cap at 5):
- Brand + category searches increase
- Brand + comparison queries rise
- Generic discovery reliance drops
- Branded direct traffic grows steadily
- Fewer “what is…” queries late-stage
Why this can’t be gamed:
Search intent reflects belief, not promotion.
Interpreting the Score
| DDI Score | Meaning |
|---|---|
| 0–9 | No default forming |
| 10–14 | Early influence, fragile |
| 15–19 | Default forming |
| 20–25 | Default established |
The Non-Negotiable Rule
If effort keeps increasing as scores stay flat, you are not compounding.
Defaults reduce effort over time. Anything else is disguised activity.
The Executive Use Case
Review quarterly. Ask only three questions:
- Which signal moved without extra effort?
- Which signal stalled—and why?
- What are we doing that does not affect this index?
If an initiative doesn’t move the DDI, it does not deserve priority.
The Final Line
You don’t measure defaults by how loud you are.
You measure them by how often people proceed without needing to ask.
That’s what this index protects.
