IEEE 1484.20.2 Recommended Practices for Defining Competencies was developed to promote a common understanding for those involved in defining policies, standards, and data structures for competency definitions and frameworks. It discusses various approaches for developing competency definitions and frameworks and incorporates and promotes the principles of ethical development, definition, documentation, and reuse of competency definitions and frameworks. However, these recommended practices cannot replace the role of experts who have developed specific domain expertise that is invaluable to organizations developing specific competency definitions and frameworks.
