You need to start by clarifying what skills are needed to be effective in Your target role, or the ‘Criteria’ for measuring a person’s performance - these are the skills required for the role you have in mind, eg Teamwork, Problem Analysis, Leadership, etc.
Your organisation may already have a set of Criteria for your target role, and if not, you will need to establish these. A&DC works with an extensive list of 35 Behavioural Criteria (Competencies) and suggest that you keep to a practical number, maybe around 8 and ensure they are clearly related to the target job role.
Organisations with their own Competencies will need to map them against the 35 Criteria that we work with in our AC-EXS range. We provide a competency mapping framework in the AC-EXS Catalogue or you can download the framework here.
