What might be some of the benefits of organizing the firm’s research efforts in this manner?

Discussion Question: At a pharmaceutical firm, researchers are assigned to clusters of diseases (mental health conditions, autoimmune diseases, neurological diseases) rather than to a specific drug research project. What might be some of the benefits of organizing the firm’s research efforts in this manner? (p. 72 in Project Management Textbook)

NOTE:
Discussion posts should be insightful, thorough and interesting. They are insightful through your analysis of the material and thorough in your complete response to the question. An excellent discussion post demonstrates that you understand the topic and, if possible, shares personal examples and experiences on the subject. Your post should be interesting by including new and useful information for the readers. The excellent post uses two or more examples from the textbook or other resources (journal articles, books, white papers, professional/academic web sites, etc.). Everyone in the class has the textbook, so bringing new knowledge and new references to the discussion distinguishes the higher-level posting.
