The SPI Group helped Merck create an online resource to help the company's 14,000 managers effectively communicate with their employees about Merck Public Affairs issues. Information about these issues was previously communicated through e-mailed messages about breaking news.

Merck managers who have approved access to MC² can learn about important Merck Public Affairs topics, the company's position and how to communicate those topics to their employees. MC² areas include: e-News for Managers, including news about healthcare, corporate finance, production and research and social responsibility; Communication Resources, Tips and Techniques for effective employee communication as well as Training Tools. The MC² intranet site was created as a companion site to Merck's Employee Communications Connection (EC²) (see EC² case study).

In its first month of introduction, MC² enjoyed nearly 7,000 unique visitors, which generated more than 23,000 page views.
