Systems Development Lifecycle homework help

Understanding health care information systems planning and
implementation is an important skill for health care leaders. Technology
is advancing and the adoption of information systems in healthcare has
progressed from being just a cool tool to a must have in terms of
quality, access, profitability, and competitiveness. It is inevitable
that managers and/or leaders will be faced with technology changes
and/or upgrades; making the need to understand the basics of health care
information system development and the standards required fundamental. 
Health leaders are charged with mandating and facilitating set
data/information standards (classification, codes, data, etc.) set forth
by the HITECH Act and HIPAA. One such standard is the Nationwide Health
Information Network (NwHIN) which enables health information exchange
on the worldwide web.  In a 300 word initial response, address the
following points:

• Discuss the processes that are involved in a systems development lifecycle (SDLC).
  • Explain each process and how they relate to one another.
  • Apply each process.  
• Discuss how the SDLC processes are used in health care information system development.
• Discuss the four methods of development of health care
  information system standards. How do these methods affect
  interoperability?
• List three organizations as well as the roles they play in development standards.
