It’s not an easy time to be a chief marketer.

Adweek has been closely following how the role is in flux. The latest report from Paul Hiebert finds that CMOs are moving in and out of the role at a faster pace than at any time in the past decade.

However, the decline in tenure doesn’t necessarily indicate poor performance. Around two-thirds of CMOs leave the job to take on bigger opportunities, according to search and advisory firm Spencer Stuart.

Marketers moving into top leadership roles tracks with the trend of more CMOs assuming responsibilities outside their traditional remit to keep pace with changes among consumers. But it’s definitely complicated. As Spencer Stuart’s Richard Sanderson said: “The marketing leadership role has become more complex than any other leadership role in the last 10 years.”
