APEX is proud to present the results of an exploratory study of 600 federal Public Service executives’ self-assessments on managing uncertainty and ambiguity. Co-authored by a renowned leadership expert, Dr. Randall P. White, and APEX’s Chief Research Officer Dr. James Kendrick, PHD, the report identifies several factors that enhance and derail effective leadership behaviour in an ever-changing and turbulent post-COVID Public Service context. Many of the factors are familiar, some research references dating back more than 30 years. However, context matters, and some of those lessons still apply today, hence the retro title Back to the Future.
