Comparison
Fractional Principal Architect vs an In-House Administrator: cost, coverage and single points of failure
A salaried administrator is fixed overhead and a single point of failure; most of the role is tickets, not architecture. A fractional principal architect with a specialist pod delivers architecture on demand, documents everything as reproducible code and SOPs, and leaves the portfolio company with no key-person dependency at exit.
| In-house administrator | Fractional principal architect | |
|---|---|---|
| Cost structure | Salary, benefits, recruiting | Fixed-scope sprints and a predictable retainer |
| Coverage | One person’s knowledge | Platform, data and edge specialists |
| Knowledge at exit | Leaves with the person | Documented as code and SOPs |
| Architecture time | Minority of the week | All of the engagement |
| Basis-point angle | Overhead regardless of output | Overhead converted to measured outcomes in the ledger |
