Cross-Collaboration: Public health has recognized the importance of coalition building and interorganizational networks to not only improve health but also obtain resources and buy-in (31). However, the PHIM suggests that a stronger emphasis should be placed on the importance of cross-silo collaborations through the application of systems thinking. Incorporating systems thinking requires (1) attention to relationships and an understanding of people, (2) specialized study to understand the parts of the public health system, (3) transcending traditional academic boundaries, and (4) matching public health problems to the appropriate method for studying them (32). While it may not be possible to completely eliminate silos within public health, systems thinking has helped public health practitioners recognize that it is “essential to link [silos] … and recognize that they represent components of a larger system” (33).
