The public is to be consulted on the government's spending as the Chancellor prepares to make "painful" cuts.
And, the consultancy company KPMG has published its own blueprint of how the public sector could be reformed to improve efficiency and productivity.
Speaking on the programme, one of the report's authors, Alan Downey, said "if we provide the same public services more efficiently, we won't need so many people to provide those services".
He added that he believed there is an opportunity to provide some of the services "more independently in different forms of organisation". If "people who run the service also own it", they will have "a real incentive not only to provide a really excellent service, to provide one also which is cost effective".
Mr Downey told Today programme presenter Justin Webb the report was "not about attacking the providers of public services" but he said that public sector could expect tens of thousands of job losses.
