According to the PMBOK Guide, Project Management is defined as the application of knowledge, skills, tools, and techniques to project activities to meet the project requirements.
* Core Purpose: Project management is accomplished through the appropriate application and integration of the project management processes identified for the project. It allows organizations to execute projects effectively and efficiently.
* Effective Project Management: Managing a project typically includes, but is not limited to:
* Identifying requirements.
* Addressing the various needs, concerns, and expectations of the stakeholders in planning and executing the project.
* Setting up, maintaining, and carrying out communications among stakeholders that are active, effective, and collaborative in nature.
* Managing stakeholders towards meeting project requirements and creating project deliverables.
* Balancing the competing project constraints, which include, but are not limited to: Scope, Quality, Schedule, Budget, Resources, and Risk.
Analysis of Other Options:
* A. A logical grouping of project management inputs...: This describes a Project Management Process.
Processes are the " building blocks " that make up the practice of project management, but a single grouping does not define the entire discipline.
* C. Launching a process that can result in the authorization...: This describes the Initiating Process Group or specifically the Develop Project Charter process. While a critical part of project management, it is only the starting phase.
* D. A formal, approved document...: This is the definition of the Project Management Plan. This document is a primary output of the planning process and a tool for management, but it is not the definition of the practice itself.
