Why do we Need EPC Diagrams

This example is based on the organizational chart from the NCEZID website. [cdc.gov/ ncezid/ org-ncezid.html]
"The National Center for Emerging and Zoonotic Infectious Diseases aims to prevent disease, disability, and death caused by a wide range of infectious diseases. We focus on diseases that have been around for many years, emerging diseases (those that are new or just recently identified), and zoonotic diseases (those spread from animals to people). Our work is guided in part by a holistic "One Health" strategy, which recognizes the vital interconnectedness of microbes and the environment. Through a comprehensive approach involving many scientific disciplines, we can attain better health for humans and animals and improve our environment.
To carry out our mission, we use many different tactics: providing leadership in public health, conducting exemplary science, strengthening preparedness efforts, establishing public health policy, sharing vital health information with the public, and building partnerships. Each of the center’s seven divisions works with partners to protect and improve the public’s health in the United States and worldwide." [cdc.gov/ ncezid/ ]
The organizational chart example "National Center for Emerging and Zoonotic Infectious Diseases" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Organizational Charts solution from the Management area of ConceptDraw Solution Park.
