DNP leaders are in position to disrupt linear traditional leadership and embark on new ideas for improvements in care delivery, organizational system processes, and policies within health care. Complexity science provides the necessary theoretical framework for nurse executives and stakeholders to interact with DNP leaders by engaging in collaborative efforts, cultivating communication from point of service providers to administrators, and coordinating interdisciplinary teams to approach gaps in practice, clinical issues, health care policy, and organizational sustainability. The DNP leader is aware that health care organizations are complex adaptive systems, continuously changing. These require skilled and knowledgeable leaders to support growth within an uncertain environment, and bring evidence to practice while promoting organizational wellness. © 2020 Wolters Kluwer Health, Inc.
