IPMA observes an increasing number and importance of projects in business, public and people's lives, also known as 'projectification'. In the world of globalisation, an increasing number of organisations are working project-based to cope with the challenges of modern times. Especially now, society is on the brink of such significant changes as global warming and artificial intelligence. Projects drive the development of new products and services, expansions, new capabilities, implementation of new strategies and new generations of infrastructure, and major maintenance and upgrade of existing facilities and infrastructure. This book provides a knowledge base for developing individual competencies for managing projects as described in the IPMA Individual Competence Baseline version 4, which encompasses: - Perspective competencies - People competencies - Practice competencies As projects become increasingly important, we must continue to realise that projects begin and end with people and that their competent performance within the broader context of the environment is at the heart of any successful project. In this book, theories and practices for all ICB4 competencies are described. They are logically sequenced, explained and enriched with practical approaches, which can be learned and applied in the daily project management practice. As such, it aligns entirely with IPMA's vision: to strengthen competence across society to enable a world in which all projects succeed. This book also supports obtaining an IPMA certificate as proof of your competence in projects.
