The following persons should include in process of EA design;
1. Health care provider from hospitals ( medical superintendent, doctors, nurses, lab technician, radiologist, pharmacist, focal of health financing, medical record units, supply chains). Their roles are to present what they want to include in architecture and giving input information required for architecture and requesting what kind of features will be easy and feasible to use(user interface).
2.IT professionals to design the EA. Their role is to develop IT architecture.
3.Informatiacian to bridge the between stakeholders and IT professional and develop standard data structures.
All the above mention personal are needed in process of EA development. Current situation, stakeholders are directly contact and develop their own architecture which become lack of interoperability and standard data structure.
Important thing is initiative and innovative of government. Without government concern, such development can not be made.
