The document discusses two approaches to outsourced recruitment process (RPO) solutions: an HR back-office solution and an end-to-end solution. While both can increase hiring, the study found that the end-to-end solution yielded twice as many hires as the back-office solution due to the back-office model's tendency to replicate steps already completed by the provider. This replication confuses candidates and adds unnecessary time to the process, reducing hires compared to the seamless end-to-end model. The document recommends an end-to-end solution for maximizing hiring outcomes from outsourced recruitment.
