Behavioral Strategist

Definition. A behavioral strategist is a practitioner who defines the desired outcome and population, generates and evaluates candidate behaviors, selects or invents the highest-fit behavior, validates Behavior Market Fit in real contexts, and designs the system of products, programs, policies, and operations that enables and sustains the behavior.

What a behavioral strategist does

• Defines the target behavior and population with operational precision.
• Screens candidate behaviors for Identity, Capability, and Context Fit.
• Translates validated behaviors into product, program, or policy requirements.
• Defines behavioral success metrics (Δ‑B, TTFB, bPMF) with denominators and windows.
• Establishes evidence discipline so decisions aren’t based on self‑report alone.

When to hire or assign this role

You need a behavioral strategist when:

• The outcome is clear but the right behavior is not.
• Behavior is the main constraint on adoption, adherence, or retention.
• Teams keep shipping features without durable behavior change.
• You need an accountable process for validation before scale.

Core outputs

• Target behavior definition (who, what, when, where)
• Behavior Fit Assessment for candidate behaviors
• Validation plan aligned to the Four‑Fit sequence
• Behavioral KPI specification with explicit measurement windows
• Decision memos that document evidence and thresholds

How this role fits into the system

Behavioral Strategy is the discipline; the behavioral strategist is the person accountable for applying it.

• Use the Behavior Fit Assessment during Research in DRIVE.
• Map outputs to Four‑Fit gates.
• Validate against cases and the evidence ledger.

Not a “behavioral designer” job title

A behavioral strategist is upstream of design. Design executes the strategy; Behavioral Strategy determines whether the behavior is right and feasible.
