Final answer:
Activity-on-Node (AON) is a project management technique used for creating network diagrams to depict activity sequencing and determining project duration, which is an integral part of the PMBOK standards.
Step-by-step explanation:
The question refers to Activity-on-Node (AON) which is a network diagramming technique used in project management. It is mentioned in conjunction with the PMBOK, which stands for Project Management Body of Knowledge, a set of standard terminology and guidelines for project management curated by the Project Management Institute (PMI). In an AON diagram, each activity of a project is represented by a node. The nodes are connected by arrows that show the sequence of activities. This technique helps in identifying the critical path, calculating the shortest project duration, and recognizing dependent tasks within a project.
Understanding AON is essential for effective project management. It allows project managers to plan and schedule activities, allocate resources efficiently, and monitor the progress of a project against its planned timeline. It is part of the larger framework of project management methodologies that ensure projects are delivered on time, within budget, and to the required quality standards.
