Fractional platform engineering vs FTE: the actual math

A senior platform IC at FTE cost, against a fractional one for a six-month outcome.

The customer’s question is not “is your technology good”. It is “what does it cost me not to hire”. That reframing matters, because the comparison is usually made against the salary rather than against the cost of not having the capability at all.

A hire is a year of commitment bought in the hope of a year of output. A fractional engagement is a specific outcome, bought for exactly as long as it takes to reach it. The arithmetic favours the second whenever the outcome is bounded — and platform work is usually bounded, because there is a moment at which the platform is good enough.
