What is business case? What business requirements does v2

address? Who are customers, stakeholders,

influencers? How will we address those needs? Should v2 coexist with v3? What is future of v2?

V2 Messaging (2)

Should development be continued? Use of v2 continue to be supported in US

and worldwide? What v3 features should be integrated into

v2? Should delimiter syntax be replaced by XML

tags? What would a V2/V3 hybrid look like?

V3 Messaging

Why is v3 messaging viewed to be so complex?

What needs to be “fixed” in v3 messaging? What is business case for v3? Who are customers, stakeholders,

influencers? How will we address those specific needs?

V3 Messaging (2)

What business requirements does v3 messaging address better than any other choice?

classes of users>

V3 Messaging (3)

Will a library of v3 messages that can be directly implemented be a solution to complexity?

How many v3 messages do we need? How do we avoid similar but different

messages? Can v3 messages be made shorter without

loss of functionality?

V3 Messaging (4)

Can a variant of XML be used Can a v3 message only carry what is specific

for that dat6aload, including only the data and enough logic structure to provide interoperability? Can v3 messaging be simplified?

What does an implementer need to borrow to implement v3 messages?

V3 messaging (5)

How important is establishing a user base? How can v3 messaging to made more

approachable to novices? What is a reasonable pathway from v2 to

v3? Is the absence of such a pathway a barrier to transition?

CDA

Who are customers, stakeholders, influencers?

How will we address those needs? How do templates, clinical statements, DCM,

and archetypes relate to CDA? Is CDA a proper method for exchange of

data? What are options?

CDA (2)

When should CDA be used and when should messages be use to exchange data?

Is there a place for both CDA and v3 messaging for data interchange?

How many CDAs should there be? How do we control CDAs with minor differences, developed by different groups?

How can CDA complexity be reduced?
