Bit misleading, 2 engs also needed office seats, couple of engs in pairs so just had one license per pair to start with.
The business covers a few sectors, some admin staff are function based, not sector based. Efficient in many ways - but not for implementing protean!
Looking at the figures I gave it does seem admin heavy I admit! However don't forget we we going from almost 100% paper-based to totally paperless - so actually admin load dropped hugely.
Long long overdue and very scary, but well worth it.
