From a website it stated, “Market Competition increased, with supply market seeing continuous mergers and acquisitions, resulting in consolidations and CROs”( clinical leader website). I think the reason for the outsourcing is because it may be to much work for one company to simply do. They may not have enough specialized employees to do the work. Employees may not want to work for the company. The bottom line is going to other companies helps to limit the amount of work an entire company may have to do. Therefore outsourcing may be a better approach because having to involve multiple processing groups may not be manageable for the PM who is in control of the overall project.
