The biggest worry on executives’ minds around the world isn’t recession, global competition, or labor relations. It’s not even cyber-security.

A new research study, the Global Leadership Forecast 2018: 25 Research Insights to Fuel Your People Strategy, shows that what’s keeping C-level executives up at night is their people strategies. The data revealed that executives rank developing “next gen” leaders and failure to attract and retain top talent as their biggest challenges in the coming years by a wide margin. In fact, only 14 percent of CEOs believe they have the leadership talent to execute their strategy.

Produced as a collaboration between DDI, The Conference Board, and EY, the 2018 Global Leadership Forecast is one of the most expansive leadership research projects ever conducted. Now in the eighth edition since DDI published the first GLF in 1999, this year’s study includes data from 25,812 leaders and 2,547 human resources professionals at 2,488 organizations across 26 industries worldwide.

The full GLF report delivers 25 deep insights about corporate leadership around the world. Among these insights, six leadership mega-trends emerged:

1. Digital is reshaping the workforce

Key finding: Digital pioneers—defined as the top 25 percent of organizations with the strongest digital leadership capabilities—financially outperform other companies by 50 percent.

The impact of a digitally transforming workplace influenced nearly every aspect of the research, revealing that organizations that have digitally-savvy leaders are significantly outperforming the average. In sync with the financial findings, the study showed that there are substantial differences in leaders’ skills at organizations considered “digital pioneers” compared with “digital laggards.”

2. Data is creating a more inclusive, agile, and fair workplace

Key finding: Organizations with more women in leadership are 1.4 times more likely to have sustained, profitable growth.

Successful organizations continue to rely more heavily on big data to inform their business strategies, and their people strategies are no exception. By tying people analytics to business results, organizations are seeing how greater diversity in leadership positively affects the bottom line, and how diverse leadership capabilities better prepare organizations to handle disruption.

3. A diverse, purpose-driven culture defines success

Key finding: Purpose-driven companies outperform the market by 42 percent.

Culture emerged as a major driver of leadership success in the study. The data showed that, for leadership strategies to succeed, organizations must build solid cultural cornerstones, such as a clearly communicated purpose, peer coaching, experimentation and psychological safety. Diversity also plays a major role in building a successful workplace, which includes embracing gender diversity, leveraging diverse mindsets, and understanding the relationship between Millennial, Generation X and Baby Boomer leaders.

4. DIY doesn’t work

Key finding: 55 percent of organizations in the top third for financial performance have formalized mentoring.

A “do it yourself” mentality leads to leadership failure. GLF data provided clear evidence that leaders are increasingly expected to work in shared leadership environments, and that leaders increasingly need to build relationships with mentors to find success. Additionally, organizations that rely on a self-directed, insular approach to learning are failing to engage leaders in meaningful development.

5. Finding new sources of leadership potential is crucial

Key finding: Organizations that extend development of high-potential talent below senior levels are 4.2 times more likely to financially outperform those that don’t.

In the past, organizations have often had a narrow definition of the “type” of person who has leadership potential, and have invested their resources into developing a very small group of people who meet that criteria. The GLF, however, showed that organizations that take a broader view of leadership potential prove to be more financially successful, feature stronger top leaders and have more women in leadership.

6. HR is losing its influence

Key finding: On average, companies excelling at people analytics are 3.1 times more likely to outperform their peers financially. But as HR’s digital skills continue to lag, attempts to adopt people analytics are increasingly failing.

Over the past three years, HR’s reputation has gotten worse, with more leaders now believing that HR is simply a “reactor” that executes commands rather than an “anticipator” that develops a people strategy that enables the organization’s business strategy. One of the primary challenges is that HR is failing to develop digital skills on pace with technology advances, which undermines their ability and reputation to drive digital transformation across the workforce.
