John Zaleski December 22, 2011, 6:47 am I started my healthcare career after 5 years in the aerospace industry. My decision was based on a personal event involving a family member--and seeing from the outside some of the key challenges that faced healthcare. This changed my own focus on healthcare, caused me to go back to school, and has been a singular focus in my life. I agree 100% that it will take more than people in healthcare to solve healthcare's problems. Systems engineering and the idea of system of systems integration is a concept which can be taken directly from the aerospace sector and points directly at one of healthcare's chief challenges: interoperability. This applies to mHealth and the enterprise.
