Reference
PMBOK
Abbreviation for “Project Management
Body of Knowledge,” which is a standard framework for project scope management based on a body of knowledge
advocated by the U.S.-based Project
Management Institute (PMI).
“Project scope management” is a management technique that analyzes
the final deliverables of the project and the work scope required, and manages the relationship between the deliverables and work scope.
The “Project Management Body of Knowledge (PMBOK)” is an international standard that provides guidelines for project managers to execute
projects in an integrated manner using project scope management techniques.
PMBOK recognizes the nine knowledge areas listed below.
Scope
Define the deliverables and work scope.
Time
Coordinate the work processes and schedule.
Cost
Determine the budget.
Quality
Define the quality targets and inspect the quality.
Human resources
Procure and train the project members.
Communication
Achieve mutual understanding and share information between
the project members and teams.
Risk
Predict the risks and determine countermeasures to avoid and
address the risks.
Procurement
Select the necessary resources, issue orders, and sign agreements.
Integration
Integrate the other knowledge areas and manage the overall
project.
The key characteristic of PMBOK is that it achieves an overall balance of
these knowledge areas to enable flexibility in response, even if there are
significant changes to the deliverables or work scope.
