Phil Anderton has been named as the Scottish Rugby Union's new chief executive with immediate effect.
Scottish rugby is in need of a massive overhaul
Anderton, who was previously the SRU's marketing director, replaces Bill Watson, who was sacked last December.
He admitted the task of revolutionising Scottish rugby was a big one, but one he was capable of taking on.
"Scottish rugby has a great future if we go about it the right way. The time and opportunity for change are here and the groundwork is under way," he said.
"The next few months will be crucial. We all have to be bold and radical in our thinking and build on the many positive aspects of the game. We have to expect that change will not be universally welcome, but doing nothing is not an option," he added.
"There are opportunities to make a real difference that will bring tangible benefits at all levels of the game, from grassroots to international teams. I just want to get on with the job, now.
SRU chairman David Mackay sees Anderton's appointment as key to his planned revolution of Scottish rugby.
"Phil has more than measured up against a number of talented candidates identified in a search that was international in its reach," he said.
"Over three years Phil has completely transformed the SRU's commercial activities and has brought new dimensions to the way the organisation thinks and acts.
"He has demonstrated a wider range of talents and skill than his current role demands and the board is delighted that he has accepted the job.
"Phil has an intimate knowledge of sport and rugby, particularly in Scotland, and he understands the need and the urgency for change in how the game is run and structured.
"He is a modern, forward-looking manager and in his new role, he will be able to make an immense contribution to shaping a successful future for the game in Scotland."
Since Anderton joined the SRU in June 2000 commercial income has risen by £11m, while sponsorship income has trebled.
However, the SRU remains heavily in debt and the game is widely considered to require a massive overhaul from grassroots level to international level.
To that end, a wide-ranging review of the game is under way.
