DDI launches Strategic Leadership Experience to prepare emerging executives for senior roles

DDI has launched the Strategic Leadership Experience, a two-day immersive simulation designed to prepare mid-level leaders and emerging executives for senior leadership roles. The programme addresses the gap between traditional development timelines and the accelerated pace at which leaders are moving into enterprise leadership positions. Participants undergo leadership style assessments before assuming control of a simulated company, where they make strategic decisions, manage trade-offs, and communicate with stakeholders under pressure. The experience provides immediate feedback, allowing leaders to adjust their approach in real time. MSA Safety piloted the programme with directors and senior leaders. All participants reported the experience was relevant to current challenges, with 94% planning to apply learnings within 30 days. The simulation can function as a standalone experience or integrate into broader leadership programmes.

DDI Named to Forbes America's Best Employers 2026 List

DDI named to Forbes America's Best Employers 2026 list. Feb 10, 2026, 10:31 ET PITTSBURGH, Feb. 10, 2026 /PRNewswire/ - DDI, a global leadership company, announced today it has been named to the Forbes America's Best Employers 2026 list for the third year in a row. This prestigious award is presented by Forbes and Statista Inc., the world-leading statistics portal and industry ranking provider. The awards list was announced on February 10, 2026, and can currently be viewed on the Forbes website. America's Best Employers have been identified in an independent survey from a vast sample of over 217,000 U.S. employees working for companies employing at least 1,000 people within the U.S. "We are honored to receive this recognition and are deeply proud of the incredible team we have built at DDI," said Tacy M. Byham, Ph.D., CEO of DDI. "Our employees are at the heart of everything we do, and this award reflects our ongoing dedication to creating a workplace where everyone feels valued, supported, and empowered. We believe that when our employees thrive, our company thrives, and this recognition is a testament to that philosophy." The final score is based on two types of evaluations: * Personal - Given by employees themselves, also known as direct evaluations. * Public - Given by friends and family members of employees, or members of the public who work in the same industry (also known as indirect evaluations), with a much higher weighting for personal evaluations. The result is two sub-lists: one for "Midsize" organizations (those with 1,000 to 5,000 employees) and one for "Large" organizations (those with more than 5,000 employees). Statista publishes hundreds of worldwide industry rankings and company listings with high-profile media partners. This research and analysis service is based on the success of statista.com, the leading data and business intelligence portal that provides statistics, relevant business data, and various market and consumer studies and surveys. "At DDI, we strive to nurture a culture where our people can excel while driving meaningful impact," said Kelli Buczynski, Chief People Officer. "Our focus on living our values and championing growth has shaped a workplace where associates take pride in advancing DDI's mission to develop better leaders for a better future."
