Experts agree that the set of different  strategies, such as disposal, facility management activities, maintenance  activities and etc, represents pro-active public real estate management. And  also, it appears that the reduction of costs of lease is a part of enhancement  strategies for public properties, for this reason, it cannot be assessed  separately from the others.
Considering all strategies that can be  adopted for public properties in an integrated and systematic approach, the  process of costs of lease reduction could allow: to reduce public spending, to  use more efficiently the spaces underused, to concentrate maintenance tasks in  fewer assets and to define with greater certainty the surplus property to be  divested or transform.
The objective of this research is to verify  and to assess technical and economic feasibility of public spkaces  rationalization plan in Italian context by establishing a management model to  support decision-making process on reduction costs of lease.
Determining the technical and economic feasibility of the public spaces rationalization could help: to implement a  project in progress but not examined in depth, to assess available alternatives  during program design phase and also - in case of negative result (not  feasible plan) - to concentrate public resources (financial, technical, human)  on other strategies that lead to better results, or again, it's an opportunity  to improve weaknesses of rationalization plan.
A number of  questions arise against this background:
