RCDD · Question #177

A work breakdown structure is:

The correct answer is A. Influenced by market conditions at the time of the project execution. A Work Breakdown Structure (WBS) is a scope-decomposition tool whose deliverables and work packages can shift in response to external factors, including market conditions that affect what work must be performed during project execution.

Why each option

A Work Breakdown Structure (WBS) is a scope-decomposition tool whose deliverables and work packages can shift in response to external factors, including market conditions that affect what work must be performed during project execution.

AInfluenced by market conditions at the time of the project executionCorrect

A WBS defines the total scope of work for a project, and because the deliverables and work packages it contains are tied to real-world constraints - such as material availability, labor market conditions, or demand shifts during execution - the structure can be influenced by those external market conditions rather than remaining fixed regardless of environment.

BA set of accounting codes

Accounting or cost codes belong to a Cost Breakdown Structure (CBS) or chart of accounts, not a WBS, which organizes work deliverables rather than financial tracking codes.

CReflective of project organizational structure

Organizational hierarchy is reflected in an Organizational Breakdown Structure (OBS), not a WBS, which focuses on work deliverables rather than reporting relationships.

DEasily standardized

A WBS is inherently project-specific because it is built around unique scope and deliverables, making it impractical to standardize across different projects.

EA replacement for a Gantt chart

A WBS and a Gantt chart serve complementary but distinct purposes - the WBS defines what work must be done (scope), while a Gantt chart shows when tasks are scheduled (time), and neither replaces the other.
