It is a striking, eight-strong line-up and in terms of its scale and personality, it is about as uncharacteristic of a McCann management team as it gets. The fame of the assembled talent suggests that Howell has a salary budget able to trump even that of Garry Lace when he was given the job of turning Grey around.
Howell's first step was to sign long-time colleague and friend Robin Price, the finance expert who helped him found Howell Henry Chaldecott Lury in 1987. This hiring was followed with the appointment of Robert Campbell as the executive creative director.
On the creative side, Campbell has lured Frank Lieberman as his executive head of TV and Mark Reddy as the executive head of art, two highly acclaimed veterans with the kind of experience needed to turn around the agency's print and TV output.
The appointments of Damian O'Malley as the executive head of planning, Stephen Whyte as the chief executive and Christian Hinchcliffe as the marketing director complete the line-up.
Howell asserts: "If an agency has got great talent then clients respond to it and they encourage you, allow you and almost cajole you to do better work. If you have these three things and manage your process properly, you make money. Money is the result, not the purpose."
Campbell, meanwhile, has high hopes for the agency's creative output.
"We'd like to be as good as Bartle Bogle Hegarty," he states. "We're playing in the same area. We've got the hardware BBH would envy in terms of clients and the network."
He believes the agency's initial focus should be on global work, which will in turn solve McCann's domestic problems. "It's about the ability to deliver creatively and strategically - it's about ideas, not ads," he says. "It's obvious this is what we should be doing."
Since Howell joined a year ago, the agency has lost several lucrative clients; Norwich Union, Somerfield, Birds Eye frozen foods and Greene King. Also, Coca-Cola handed its main UK branding account to Mother and Bacardi asked agencies to present global creative ideas.
The new top team must act fast to reassure the remaining clients of McCann's competence. Long-term clients suffered no fewer than eight agency heads between 1985 and 1995, while the sacking of the chief executive Ben Langdon in 2003 created a sense of chaos at the agency.
Not only must the new team convince clients they are there to stay, they need to inspire confidence among its bruised staff of 280. "We now have to connect the rest of the agency with what we're doing," Campbell says. To achieve this, the agency has instigated a training and redevelopment programme, details of which are being closely guarded.
Lieberman, for his part, is rebuilding a skeletal TV department. Creative services, including traffic, were casualties of the recession era when the agency was led by Langdon.
O'Malley is tasked with restoring the planning department's confidence, which was shattered back in 1989 when the then creative director, Jerry Green, famously told ±±¾©Èü³µpk10 that the department was "dead from the neck up".
"It's a ground-up rebuild of a dysfunctional agency," Campbell explains. "It will take one year to get it functional and two years to get it good."
Howell is characteristically bullish: "I inherited the best goddamn client list in the world," he says.
"McCann in London has been cosseted by this 28-strong global client base, which has protected it through the thick and thins, so it hasn't had to face the hard realities of the recent market," he adds.
As the lead agency in Europe, strengthening London is key to building the network across the region, which is of concern to Howell and Campbell, who are the president and the vice-president of EMEA respectively.
"To be the dominant global player, you've got to be number one in London, Japan and New York," Howell says. "We're already the number-one non-Japanese agency in Tokyo."
The team has worked hard to secure the Bendicks and Signet UK accounts and also to find a place on some domestic pitchlists, but there is a long way to go.
Howell is not known for hiding his achievements under a bushel, and there is an ominous sense of self-confidence among the newly assembled team.
The successful track records of most of its members, many of them very lucrative, could mean it is less hungry to prove itself than a group of people setting up for the first time.
