A CMO Council study reports that surveyed top marketing executives say poor performance has led to a lack of influence within the corporate hierarchy, writes BtoB Online (via MediaBuyerPlanner). Only 10 percent of respondents to the survey said their marketing groups are "highly influential and strategic" within their company. Less than half said their teams are "well regarded and respected"; however, two-thirds of CEOs (polled in a separate survey by Chief Executive magazine) said their marketing groups are "mission critical" for creating top-line growth.
