This thesis presents a professional development action plan or framework for Instructional Designers working as external consultants for corporate companies. It also contains justifications and data on why such an action plan is necessary for these professionals. The thesis recommends flexible learning as an approach to help practising Instructional Designers to continuously and proactively learn about new trends, approaches, technologies and theories in the field of Instructional Design as well as other related fields. Only well-informed Instructional Designers are able to design relevant and useful instructional material to help their clients to stay relevant and competitive in the global scene, thereby keep jobs for their employees. Instructional Designers must be well-equipped with current knowledge, skills and attitudes to ensure that their instructional materials help employees to stay employable as long as possible within given shorter and limited time and resources.
