Northern Ireland's representative on the new body to replace the BBC's Board of Governors has promised to represent the views of licence fee payers.
Rotha Johnston promised to listen to BBC licence fee payers
Rotha Johnston, an entrepreneur, was speaking after being appointed to the BBC Trust which begins work next year.
The eight trustees will join three current governors and BBC chairman Michael Grade on the new board.
Ms Johnston said she would ensure the BBC is "an efficient and accountable public broadcasting service."
"I am looking forward to working with the BBC Audience Council Northern Ireland to listen to and understand the public's expectations in return for their licence fee," she added.
She will also chair Northern Ireland's Audience Council, which will replace the old Broadcasting Council.
Fabian Monds, the outgoing National Governor for Northern Ireland, said he welcomed her appointment.
"The new trustee and council will have important roles to play in championing the interests of local licence payers and in ensuring that the BBC remains responsive to their needs," he said.
Another trust member with a Northern Ireland link is vice chairman designate Dr Chitra Bharucha.
Dr Bharucha spent more than 20 years as deputy director of the Northern Ireland Blood Transfusion Service and consultant clinical haematologist at Belfast City Hospital.
She is a former member of the BBC Broadcasting Council for Northern Ireland and also served as the Northern Ireland member of the Independent Television Commission.
The eight new members have been appointed for a four-year term.
It is intended that the Trust be more removed from BBC management and more accountable to licence fee payers.
The trustees will earn between £35,000 and £40,000 per annum for working two days a week.
