Portfolio optimisation is right-sizing an organisation’s entire property portfolio against real demand: which buildings to keep, shrink, exit or open, and how work patterns spread across them. It is the multi-site version of the single-office space question.
The inputs are lease events, utilisation by site, headcount plans and commute patterns. Organisations that measure attendance consistently across sites can compare like with like; those that do not end up negotiating leases on anecdote.
