Competencies At Work will equip readers to understand, build, and implement competency models as a foundational and integrating element in talent management systems. Readers will understand how competency models have evolved to be the current best practice in defining criteria for all talent management applications such as selection interviews, promotion panels, assessment centers, job descriptions, and learning objectives. Specific guidance is provided in the steps needed to establish a sustainable model, with research results on universal competencies contained in most contemporary models. Also discussed are the challenges and issues in building and implementing models, such as the need for proof of efficiency and effectiveness, that is, reliable measures of competence and proof of validity.
