The Waterline Model
"Your only goal as a manager, if you do nothing else, is clear roles and clear expectations." — Molly Graham
What It Is
Imagine a team as a boat. Problems below the waterline sink the boat. Leaders often dive deep (scuba) to fix "people problems" first, but they should snorkel first. Start at the surface with structural issues (goals/roles) before addressing interpersonal dynamics.
When To Use
-
Friction, confusion, or underperformance within a team
-
Before assuming conflict is due to "difficult people"
-
When teams are fighting over responsibilities
-
As a diagnostic before any team restructuring
The Model
🌊 SURFACE (Snorkel First)
┌─────────────────────────────────────────┐
│ 1. GOALS — Does team know destination? │
│ 2. ROLES — Who owns what? │
│ 3. EXPECTATIONS — What does good look? │
└─────────────────────────────────────────┘
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
┌─────────────────────────────────────────┐
│ 4. SKILLS — Can they do the job? │
│ 5. MOTIVATION — Do they want to? │
│ 6. PERSONALITY — Is there true clash? │
└─────────────────────────────────────────┘
🌊 DEPTH (Scuba Later)
Core Principles
- Snorkel Before You Scuba
Check structural alignment before analyzing personality conflicts.
- Clarify Goals
Does the team know what the destination is?
- Clarify Roles
Does everyone know who owns what part of the elephant?
80% Rule
80% of team problems are structural, not personality-driven. Fix structure before blaming people.
How To Apply
STEP 1: Ask "What number were you hired to drive?" └── If answer is vague → Goal problem
STEP 2: Ask "Who owns [specific task]?" └── If multiple people claim it → Role problem └── If no one claims it → Role problem
STEP 3: Ask "What does good look like?" └── If answer is vague → Expectations problem
STEP 4: Only After 1-3 Are Clear └── Consider skills, motivation, personality
Common Mistakes
❌ Assuming conflict is due to "bad culture" or "difficult people"
❌ Jumping straight to personality assessments
❌ Reorganizing teams without first clarifying goals
Real-World Example
Graham often finds that when teams are fighting, simply asking "What number were you hired to drive?" reveals that no one actually knows their specific accountability.
