I can think of some factors like
Retained Volunteers, giving more time and actively participating,
Volunteers having good relations among themselves, being satisfied, staying for long
Organizations operations increasing areas of services etc.
Can you also kindly suggest related studies.
Thank You
It depends on what is the vision and mission of that organization, and what is the scope of its activity. The long term and short term goals set for the organization provide the key performance indicators when translated in numbers. I think a deep insight into the system of such organizations and ethnographic readings will help.

Thank you all. But i think i still need more resources.
Professor Allessandro, the thesis you shared looks important but it is not in English.
