Final answer:
A project, according to the PMBOK Guide definition, is temporary and has a defined beginning and end.
Step-by-step explanation:
The Project Management Body of Knowledge (PMBOK) Guide definition of a project indicates that a project is temporary. This means that it has a defined beginning and end, with a specific objective to be achieved.
For example, if a company is developing a new software application, the project starts when the development work begins and ends when the software is deployed to the users. Once the project is completed, the team moves on to other projects.
While projects consume human resources and are often limited by a budget, these are not defining characteristics of a project according to the PMBOK Guide definition.
