Maintenance & Field Services carries a process risk of 56.5 out of 100 — the elevated band, and rank 21 of 33 sectors in the Tieron reference catalog. That figure is independent of location: it is what the work itself carries. Where you buy then moves the baseline from 33.9 in Denmark to 68.2 in Russia. Every figure below shows its weight and its source.

Country and sector are 50% of Tieron’s risk axis by weight — the half that is knowable from public data alone. The rest is supplier-specific: conflict minerals exposure (weight 0.10), incident history (0.10) and information opacity (0.10). Two maintenance & field services suppliers in the same country start from the number above and end up far apart. Impact — spend, substitution difficulty, continuity criticality — needs your own ledger.
Process risk, highest first — independent of where you buy.
