- 2.6 to 1, top to median
We publish the pay ratio every year. It rose from 2.4 because two partners took on Rotterdam's lease.6
Travel footprint
Trains between the studios, one flight per project for site visits.
What we got wrong
Two projects ran over. One estimate was off by a third.
P-030 shipped three weeks late
The spectrometer's firmware changed twice during testing. We now freeze the device API before design starts, and we said so in the contract.
P-032 needed 34% more engineering hours
We underestimated how much historic grid data needed cleaning. We absorbed the cost and added a data audit to every Data quote.
A wrong figure in last year's report
We printed 214 Northline stops. The right figure is 212. The corrected PDF is online and the change is noted on page 2.7
