# Capacity Buffering

**Capacity buffering** is a risk-management and sustainability tactic: when taking on a new client, deliberately build *margins* into **both** your *pricing* **and** your *availability estimates*.

The reasoning is specific to the fractional context. Because engagements often involve **startups with ambiguous needs**, the work can unexpectedly become more complex or suffer *scope creep*. Two buffers address two failure modes:

- **Buffer availability** → you don't overcommit and trigger burnout when scope expands.
- **Buffer price** → you remain adequately compensated for unforeseen complexity.

Crucially, because **each client only sees a fraction of your total portfolio**, they cannot see your aggregate load — so *you* must **proactively advocate** for these boundaries. The concrete procedure, including the decision to decline or re-negotiate a separate fee when scope grows, is [[action-build-buffers]]. Buffering is what makes a [[concept-portfolio-career]] survivable long-term.

**Enrichment / outside view.** Fractional-executive sources emphasize *clear scope, short contracts, and avoiding misunderstandings*, which supports the buffering logic. The specific move of deliberate *pricing and availability* buffers is an **inference** rather than a directly quoted best practice — but a reasonable one, well-grounded in **boundary theory / role strain** research and in consulting literature on **scope-creep management** (retainer design, change-order discipline).
