This report describes my projects and major activities during my internship with Eli Lilly and Company. As a Scientific Communications Associate, I worked in a highly cross-functional group at Lilly to create documents the company sends to regulatory authorities worldwide. This report provides a basic description of the organizational structure and culture, the nature of my work and the types of documents I created, my contributions to Lilly during the internship, as well as my interactions with an internship mentor. Several projects, including work on ethical review board responses and intranet virtual space design are highlighted. The process I used to complete one of my major activities, updating a Clinical Investigator’s Brochure for a Lilly compound, is described in detail. My analysis of the communications process I used to update the Clinical Investigator’s Brochure, using Paul Anderson’s problem-solving model, is also included.
