Performance-IconA new study has lambasted marketers’ financial skills and the marketing programs run by education providers, claiming that as many as 90% of marketers are not trained in marketing performance and ROI, partly due to the fact that nine out of 10 marketing courses don’t have a unit focused on the topic.  Because of this educational void, 80% of marketers struggle to properly demonstrate the business effectiveness of their marketing spending, campaigns and activities to their top management, the report says.
