1. HL7 Business Architecture Model (PLA TSC Project)
Proposed CDA Product Family

2. Background
The HL7 Technical Steering Committee endorsed the following definitions of Product Families and Product Lines:
“A Product Family is a collection of products that share common elements, methodologies, and tools as viewed from a design perspective.”[1]
“A Standards Product Line is a set of specifications that share a common, managed set of capabilities satisfying the specified needs of a particular market segment and that are developed from a common set of core resources in a prescribed way.[2]”
The SAIF-CD definitions of governance, management and methodology are:
"Governance establishes rules that control decision-making." [3]
"Management makes decisions according to governance rules." [5]
"Methodology establishes processes that comply with governance rules and may introduce additional rules." [4]
