Burdon, the Tribal DDB head of strategy, and Boyd, its strategy director, will head the agency's planning department and report to Lucy Jameson, DDB's executive strategy director.
The appointments follow the departure of the DDB UK head of planning, Sarah Watson, who left the agency to join Bartle Bogle Hegarty in New York in May.
Burdon, who has been at DDB for three years, has been heavily involved in its Volkswagen campaigns, advising on customer experience and interaction. He was a key member of the team behind the groundbreaking VW Configurator iPhone app, launched in January.
Since joining DDB in June last year, Boyd has led planning on a range of accounts including Nestlé Purina and Terry's Chocolate Orange.
More recently, he has worked on expanding the scope of DDB's data function, DDB Matrix.
Jameson said: "I'm delighted to promote Dom and Drew. Putting them together to manage our diverse squad of planners was the obvious move. Together, they bring wonderfully different perspectives on how to crack brand problems of any flavour and reflect our ambition to become an innovation hothouse."
