Business Architecture Models (BAM)

  • Purpose

The purpose of the HL7 business architecture is to document how the different parts of the HL7 organization collaborate and coordinate to produce interoperable standards products to meet the needs of health information systems builders, and their customers.

  • 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]

"Methodology establishes processes that comply with governance rules and may introduce additional rules." [4]

"Management makes decisions according to governance rules." [5]
