Nearly half of CEOs believe that all of their employees have access to the data they need, but only 27% of employees agree. That’s according to study results from Teradata, a data analytics and marketing firm. The company commissioned The Economist Intelligence Unit to survey 362 workers across the globe -- including those in management, finance, sales and marketing, business development and more. CEOs also overestimate how quickly “big data” moves through their company, with 43% of CEO respondents believing that relevant data is made available in real-time, compared to 29% of all respondents. Overall, CEOs are wearing rose-colored glasses when examining the overall effectiveness big data has on their initiatives: 38% believe their employees are able to extract relevant insights from the data, while only 24% of all respondents do. The report notes that of companies that outperform in profitability as a result of data-driven marketing, 63% of the initiatives are launched by corporate leadership, and 41% have a centralized data and analytics group. Of companies that say they underperform, 38% of initiatives are launched by the higher-ups and 28% say data and analytics are centralized. “The survey is clear that organizations succeed when the data-driven vision and leadership are shared, and the benefits of data initiatives are consistently tracked, promoted, and most importantly, linked to corporate goals and business results,” stated Chris Twogood, vice president of products and services marketing at Teradata.
