Let's assume that your HR/PR system was outsourced to a firm like ADP (https://www.adp.com/what-we-offer/payroll (Links to an external site.)). What are the pros and cons of outsourcing these functions to a third-party? What additional threats would be present? Are there any special controls required? Does this make sense for a firm (say a firm that has 5,000 employees) to outsource HR/PR?
