Alternative Capacity Sources are extra resources, used to satisfy demands or get around constraints, that go beyond an organization's current capabilities. This may entail hiring temporary workers, developing cooperative alliances, outsourcing work to outside parties, or using technology. These substitutes are innovative, flexible, and economical. Examples include collaborative ventures, freelance platforms, and cloud computing. Companies use these sources strategically to ensure operational resilience and competitiveness by responding to shifting demand. Adding external components to an organization's capacity structure requires careful assessment of risks and quality control.
