Answer:
When an organization completely outsources its IR work, typically to an on-site contractor, it is called a Staff Augmentation model.
Step-by-step explanation:
In this model, the organization hires an external service provider to provide additional staff (skilled resources) to work alongside their existing team. These staff are usually placed on-site and they work under the direct supervision of the organization’s internal team to provide support and expertise in specific areas.
The staff augmentation model is a popular approach used by many organizations as it provides them with the flexibility to scale their team up or down depending on the demand.
