Multiple projects within a program frequently draw from the same pool of human, material, or financial resources. When one project consumes more than planned, it can deprive another project of what it needs, causing delays or cost overruns. Proactive coordination around shared resource availability is a core concern in program-level integration.

Scope requirements affect a single project's boundaries and are managed within that project, not typically driven by other projects in the program.
