This chapter describes foundational concepts of the PMBOK® Guide. It introduces you
to the purpose and content of the PMBOK Guide and provides definitions of projects, project management, program management, portfolio management, organizational project management, operations management, organizational strategy, business value, and the project life cycle. All of these foundational concepts are important to ensure that you understand the terminology used by the PMBOK Guide, which also appears in the PMP® exam. It is important that you take time to fully understand these concepts, because they underpin many of the processes, tools, and techniques that come later in the book.
