This section describes the roles of different parties involved in development of the Commission for Case Manager Certification’s CMBOK®, as well as how the Commission selected them. See the Biographies section for more information on individuals who contributed to the knowledge content.

Knowledge Editor, Dr. Hussein Tahan, DNSc, RN

The Knowledge Editor provided oversight, review, and quality control of the completeness, accuracy, and validity of the knowledge content of the product throughout the development of the CMBOK product. The Commission followed a rigorous recruitment and proposal process to vet the candidates and select Tahan.

Tahan worked closely with the new product development task force, the writers and copy editors, information designers, and the product development consultants to verify that the content reflects the high standards of rigor and professional standards that case managers need and expect from the Commission. Tahan continues to provide that guidance as the Commission expands the depth and breadth of content to meet even more needs of the case managers.

Subject Matter Experts (SMEs)

Subject Matter Experts (SMEs) are professional case managers who have direct experience in case management and provide expertise and specialized knowledge in particular areas of case management. They contributed to creating the case management framework as well as the written knowledge content. The Commission sought out SMEs with different perspectives and experiences in case management so that the CMBOK would reflect the knowledge needed across different case management settings.

The SMEs’ range of experience and diversity includes several SMEs with more than 20 years of experience in case management as well as one young case manager recruited to reflect the voice of the future.
