| Overtime days reduced from 247 to 14 in a 35-day cycle (94.3%) Best of five modelled scenarios at one 55-controller unit, with no change in headcount. | Published source | EUROCONTROL NMD/SAF/2653, case study 3, page 34 | /evidence/published-use-cases | 2026-09-12 |
| 8 to 12% annual workforce cost per ATC unit, 750,000 EUR/year The guideline describes this as extrapolated from the simulation to other units. The simulated result is one fewer controller in one unit over a 30-day cycle. | Published source | EUROCONTROL NMD/SAF/2653, case study 1, page 21 | /evidence/published-use-cases | 2026-09-12 |
| 60,000 swap requests a year, 15 minutes to 1.5 minutes, 360,000 EUR/year Handling time is a reported deployment observation, not independently audited here. The euro saving is derived from it at this customer's volume and staffing. | Published source | EUROCONTROL NMD/SAF/2653, case study 4, page 35 | /evidence/published-use-cases | 2026-09-12 |

Earlier materials sometimes abbreviated the study context. Use the clarifications below when referring to those materials.
| Figure as previously published | Current context | Checked |
|---|---|---|
| "94% less overtime" with no unit size, cycle length or method Not used. Published on the previous website until 2026. | The 94.3% reduction was the best of five simulated scenarios at a 55-controller unit over a 35-day cycle, with the same headcount. It is not a general performance guarantee. | 2026-09-12 |
| "10% workforce cost reduction" presented as an achieved outcome Not used. Published on the previous website until 2026. | The annual cost figure is an extrapolation from a single-unit simulation, as described in the guideline. | 2026-09-12 |
| "Automated 60,000 shift swaps saving 360,000 EUR/year for one organization" Not used in that wording. Published on the previous website until 2026. | The guideline reports a deployment handling 60,000 requests annually. Handling time fell from 15 to 1.5 minutes on average; the annual saving is derived from that operation’s volume and staffing. | 2026-09-12 |
| Any solve time, or any number of employees rostered per unit of time Not used anywhere on this site. | No production-scale solve-time benchmark is published. Performance should be evaluated against representative requirements and data. | 2026-09-12 |
