This commentary addresses the Office of Personnel Management's stated challenge of creating a high-performance culture across the U.S. federal government, as articulated in a December 8 memo by OPM Director Kupor. The author argues that while OPM's recent structural changes — including Senior Executive Service overhaul, revised performance standards, and the Federal HR 2.0 system — are necessary, they are insufficient without addressing 'softer' dimensions such as leadership quality, psychological safety, behavioral change, and capability building. Drawing on the HPO Center's research identifying 35 characteristics of high-performance organizations, Korn Ferry trust data, McKinsey's organizational health studies, and GAO's High Risk report, the author contends that federal HR systems have historically been decoupled from agency performance outcomes. The commentary identifies specific barriers including the General Schedule system, politically influenced leadership gaps, and the morale damage caused by recent unplanned workforce reductions. The author concludes that current levels of employee distrust and institutional disruption make meaningful cultural transformation unlikely in the near term. Key insights: OPM's December 2024 memo identifies 'creating a high-performance culture' as the leading management challenge, yet the associated initiatives focus on structural and administrative changes rather than behavioral and cultural dimensions. The HPO Center's research identifies 35 characteristics of high-performance organizations across five factors, with 28 of the 35 involving human behavior — suggesting that structural reforms alone are insufficient for cultural transformation. Unplanned federal workforce reductions have been reported to destroy morale, create trust deficits, and produce 'survivor syndrome' among remaining employees, compounding pre-existing barriers to high performance. Practical takeaways: Organizations undergoing workforce reductions may experience 'survivor syndrome' among remaining staff, with disengagement and psychological safety erosion identified as measurable consequences requiring active management attention. The cancellation of the 2025 Federal Employee Viewpoint Survey is noted as an indicator of OPM's awareness of workforce sentiment problems, suggesting that alternative listening mechanisms such as Employee Resource Groups may serve as proxies for formal engagement measurement.
