As the Director of the Portfolio Management Office at your worldwide furniture store, you prepare a series of reports on the status of the portfolio. One report that you use is a bubble diagram. In…

The core purpose of a supply-and-demand bubble diagram is to compare what the portfolio needs (required resources) against what the organization has (available resources); this side-by-side visual representation enables the portfolio manager to pinpoint overallocation, underutilization, and reallocation opportunities across active components.

Resource availability plotted against life cycle phase shows scheduling context but does not directly represent the supply-demand gap that the diagram is intended to illuminate.

Resource competency and component probability of success addresses skill-fit and risk scoring, not the capacity balance between resource supply and demand.

Resource importance and probability of success is a prioritization and risk lens, not a supply-and-demand framework appropriate for resource capacity analysis.
