Scottish coach Jim Duffy took over as Norwich City's Assistant Manager on 9th February 2007 replacing Doug Livermore who had resigned with immediate effect. Peter Grant said “We are very fortunate to have secured the services of someone with Jim's vast experience and knowledge of the game. He was an excellent player, he's been an excellent coach north and south of the border and he's got an impressive managerial CV. Other clubs have approached him and that's why it was important for me to get him down here to sell Norwich City and what we're trying to do here to him. Jim's knowledge of the game in England and Scotland is huge and that's going to be a major plus for me and for Norwich City.”

Glasgow-born Duffy's playing career took in Greenock Morton, Dundee and Patrick before he returned to Dundee as player/ manager.

He joined Hibs as manager and coached at Chelsea and Portsmouth before returning to manage Dundee. In 2005/6 he joined the coaching staff at Hearts, but lost his job as Director of Football, along with Graham Rix, in March.

Earlier in 2006/7, he rejected managerial approaches from Cambridge United and Dublin side Bohemians.

Duffy was appoined as Norwich's caretaker manager on 8th October 2007 following the departure of Peter Grant. Three defeats in his period in charge did not help Duffy win the permanent contract in charge of City and following Glenn Roeder's appointment, Duffy left the club.

After working in the media, Duffy was appointed as manager of Scottish Second Division side Brechin City on 9 January 2009. He replaced former Northern Irish international Michael O'Neill who left Brechin to take charge at Irish side Shamrock Rovers. Duffy lasted until late May 2010 when he resigned.

On 8th February 2011, Duffy was appointed manager of Clyde who, at the time of the appointment, were rock bottom of the Scottish Third Division having won only once in the league this season. He replaces Stuart Millar, who was sacked the week before. Duffy said: “I am delighted to become manager of Clyde as it is a club which has played a long and distinguished part in the history of Scottish football. Clyde have had some turbulent times in recent seasons, so we will need everyone to work extremely hard to try to gain a level of respectability. Only once this is achieved can we start to look to a brighter future. I cannot wait to get started.”

On 1st February 2012, Duffy was appointed to Clyde's board. Duffy told his club website: "It is a honour and a privilege to become a director at Clyde. My priority remains the football side of the club and building up its infrastructure, but I will help wherever I can and I look forward to working more closely with the board," said Duffy. Clyde said it was "an important step in bringing greater stability to the club and represents a determination to put a structure in place that optimises the development of Clyde FC. On inviting Jim on to the board, it demonstrates our desire to utilise all of his experience as we work together in taking the club forward."
