The book offers a well-grounded vision of the significant theory and application of the concept of Capability as a lifecourse and lifespan development. Capability is argued to be a necessary 21st century process and outcome (PROUT) of all learning development and activities across formal and informal places. 
Capability has been defined as a way of understanding people and organisations through their holistic approach which moves beyond Competence to show how potential ability, self-efficacy, and values, as basic, intertwined elements lead to how Capable People and Capable Organisations offer flexibility and adaptability in action.
It presents the case for Capable Four-Dimensional Learners who can thrive in various situations to solve unfamiliar problems and challenges. These learners have developed and can demonstrate Lifelong commitment to learning. In addition, four-dimensional learners need to experience a broad range of areas of Lifewide learning. Further, learners need to include learning of some aspects in depth, that is, Lifedeep learning. An understanding of the impact of technology, as a significant element in human learning beyond being operational tools, as Lifetech learning is vitally necessary. How this four-dimensionality relates to better sustainability awareness and application through personal and organisational Capability is outlined.
This book emerged from many years of theory development and research with critical examination of the Capability Concept and its application as a Learning Model. It is written for students, teachers and administrators at all levels of Education, and everyone interested in human learning theory and application.
