The book "Agile Portfolio Management" deals with how an organization identifies, prioritizes, organizes, and manages various products. This process is carried out efficiently in order to optimize the development of value sustainably over the long term. It ensures that a company provides its customers with the best value for their investment. A good portfolio manager understands and follows agile principles while also considering various factors required for managing multiple teams and projects. The project management offices of many organizations face the reality of increasing agile deliveries as part of agile transformations but lack the knowledge to execute these tasks. Researchers and professionals have a good understanding of project, program, and portfolio management from a planned perspective. The knowledge for managing an agile portfolio remains limited. The purpose of this book is to give the reader an understanding of managing an agile delivery portfolio, the available options (theory), the knowledge we have (research), and the practices that others apply (practice). Many organizations in sectors such as banking or insurance are in the midst of significant agile transformations with limited knowledge of the practice. The author collects and analyzes common practices across various industries, providing both theory and, through case studies, the practical aspects of agile portfolio management.
