Why Your Team Is Falling Apart (The Dunbar Number)

Published January 11, 2026

1. The Disruption (Challenge the Model)

You think the drama in your office is because of "personalities."

"Sarah doesn't like Jessica." "Mike is lazy."

So you try to fix it with team lunches and "culture."

But the problem isn't the people. It's the Math.

You are trying to run a Wedding Banquet like it's a Family Dinner.

2. The Anchor (The Familiar Experience)

Think about a Sunday dinner with your immediate family (4-5 people).

Do you need a seating chart? No. Do you need an agenda? No.

Everyone knows where the forks are. Everyone knows who cleans up. You have Shared Consciousness.

Now, imagine a wedding with 150 guests.

If you don't have a seating chart, a schedule, and a DJ, what happens? Chaos.

3. The Reorganization (The "Oh" Moment)

Your practice just went from the Family Dinner to the Wedding.

  • Stage 1 (Start-up): You + Assistant + Front Desk. You have Shared Consciousness.
  • Stage 2 (Growth): You + Associate + 2 Hygienists + 3 Assistants + 2 Front Desk.

You crossed the threshold. You can no longer rely on "everyone just knowing."

The drama isn't personal. It's just people bumping into each other because there is no seating chart.

4. The Why (The Mechanism)

Anthropologist Robin Dunbar found that humans have a cognitive limit to stable social relationships.

In a business, that "Telepathy Limit" is about 7 people.

Once you pass 7, you must replace Telepathy with Systems.

5. The Solution (From Telepathy to Systems)

Stop trying to "bond" your way out of chaos. Document your way out. Here are the exact playbooks to replace Telepathy with Structure.

Playbook 1: The SOP Blitz (Document Everything)

The Rule: If a task is done the same way twice, it must be written down.

How to start:

Pick your top 5 highest-friction tasks. These are the ones where someone always says "That's not how I was told to do it."

  • How we answer the phone (word for word).
  • How we set up a tray for each procedure.
  • How we handle a same-day cancellation.
  • How we check in a new patient.
  • How we present a treatment plan fee.

Format: Keep it simple. One page per SOP. Three sections: What, How (step by step), Who (responsible role, not person).

Script to introduce it to the team:

"We're growing, and that's amazing. But we've outgrown the 'just figure it out' phase. I'm going to document our top processes so everyone has the same playbook. This isn't about control — it's about making your job easier."

Why it works:

  • Arguments disappear when there's a written standard.
  • New hires ramp up in days, not months.
  • You stop being the answer to every question.

Playbook 2: The Role Clarity Chart (Who Owns What)

The problem: In small teams, everyone does everything. As you grow, tasks fall through cracks because "I thought SHE was doing that."

How to build it:

Create a simple grid. Rows = tasks. Columns = team members. Each cell gets one label:

  • O = Owns it (responsible for completion).
  • B = Backup (covers when Owner is out).
  • X = Not involved.

Example:

  • Phone answering: Sarah (O), Mike (B).
  • Insurance verification: Mike (O), Sarah (B).
  • Tray setup: Jessica (O), Assistant 2 (B).
  • Cancellation filling: System/Chairfill (O), Sarah (B).

Why it works:

  • No more "I didn't know that was my job."
  • Backup assignments mean nothing falls apart when someone calls in sick.
  • Drama shrinks because overlap shrinks.

Playbook 3: The Morning Huddle Protocol (Daily Alignment)

The problem: Your team starts the day scattered. Everyone is reacting instead of executing.

How to run it: 7 minutes. Standing up. Every morning. Non-negotiable.

The format:

  1. Schedule scan (2 min): Who's coming in? Any complex cases? Any anxious patients?
  2. Holes and flags (2 min): Cancellations? Outstanding balances? Insurance issues?
  3. Wins from yesterday (1 min): What went well? Who did something great?
  4. One focus (2 min): Today's priority is ___. If nothing else gets done, THIS gets done.

Why it works:

  • Everyone starts with the same information. Telepathy replaced by briefing.
  • Problems surface at 8 AM instead of 2 PM.
  • The "Wins" segment builds momentum and positive bonding.

Playbook 4: The Escalation Path (When to Involve the Doctor)

The problem: Team members either bother the Doctor with everything or hide problems until they explode.

Define three tiers:

  • Green (Handle it): Patient wants to reschedule. Insurance question. Supply order. Team resolves without the Doctor.
  • Yellow (Inform after): Patient complained about wait time. Claim denied. Third no-show. Inform the Doctor at end of day.
  • Red (Interrupt now): Medical emergency. Legal threat. Equipment failure during a procedure.

Script for the team:

"Green — own it. Yellow — write it on the board, we'll cover it at huddle. Red — come get me immediately."

Why it works:

  • The Doctor stops being interrupted 15 times a day for Green-level issues.
  • The team feels empowered to handle problems without permission.
  • Real emergencies get attention faster because the signal isn't lost in noise.

Team Communication Micro-Actions

Replace "Hey, quick question" with a shared board. Non-urgent questions queue up. Review at huddle. Cuts interruptions by 50%.

End every meeting with "Who does what by when." Never leave without clear ownership and a deadline.

Celebrate publicly, correct privately. Praise in the huddle. Feedback one-on-one.

Use "we" not "you." "We need to improve at confirming" lands differently than "You need to confirm better."

Real-World Example

Practice grew from 4 to 9 people. Drama exploded. Dentist tried pizza parties and bonuses. Nothing changed.

Then they implemented 5 core SOPs, a Role Clarity Chart, and a 7-minute morning huddle.

Result after 30 days: Arguments dropped. New hire productive in 1 week instead of 6. Doctor stopped getting pulled out of procedures for scheduling questions.

The drama wasn't personal. It was structural. Fix the structure, fix the team.

The Rule Most Growing Practices Miss

Culture doesn't fix chaos. Structure creates culture.

When the rules are clear, the drama disappears. Not because people changed — because the friction did.

You don't need a team retreat. You need a binder.
