ONC S&I Framework - Use Case Simplification Key Steps Forward

2

Awareness at Kickoff

1) UCS Awareness at Use Case Project Kick-off– What would you make all workgroups aware of today? – Presentation of what the S&I environment entails and

importance of [UCS] charter– Assignment: Gary, Mike, Smriti…– Next Steps:

• Review Use Case Initiative Template• Identify points of UCS “Awareness” throughout UC

development process– Input: Reference to and re-use of UCS Components– Output: Feedback on new Component candidates or

suggested updates to existing Components

Expanded Charter

2) Review current Use Case Simplification charter– Expand scope to overall S&I– Assignment: Gary, Erik, Ed, Bob, Mike

ONC S&I Framework - Use Case Simplification Key Steps Forward4 3 November 2011

Challenge To identify a core set of constructs broadly applicable to (and re-usable in subsequent specification of) Use Cases.

Scope Statement

Scope is the common (core) set of requirements, actors, actions, data elements (names, definitions, representations, base standard source) and data element sets across all Use Case Scenarios, across the S&I Framework (and potentially beyond).

Value Statement

Common constructs:1. Ensure uniformity across Use Case specifications2. Resolve that standards-based containers (data) and protocols (functions/processes/services) offer a ready path to implementation.3. Make specifications available in a repository (with appropriate tooling) to allow rapid use case prototyping.4. Provide specifications on which users can take action to promote a common, computable understanding of health information concepts that are exchanged or stored.

Target Outcomes

1. Repository of common (core) constructs: requirements, actors, actions, data elements (names, definitions, representations, base standard source), data element sets.

2. Repository Management Tools: to add, update, query/browse.3. Use Case Development Tools: to adapt or build out new Use Cases from core constructs.

Timeline For duration of S&I Framework.

Expected Deliverables

As identified in Target Outcomes

Standards, Stakeholders

1. Applicable standards to meet requirements.2. Stakeholders represented in Use Case Scenarios.

Potential Risks

1. Use case “silo” syndrome.2. Disjunction between conceptual and implementable outcomes.3. Too narrow focus on exchange: point-to-point vs. end-to-end.4. Insufficient focus on understanding content from the sender and receivers views.

Registration and Maintenance

6) Ongoing support– Determine value of having a Registration Authority

and define a the scope of the RA role for S&I?– Consider Change Request process for S&I – Assignment: Mike, Robin– Next Steps:

Tooling

7) What tooling do we need and how fast?– Concern about cost, sustainability, etc

a) Integrated plan for tooling

b) Value to the community

– Assignment: Kevin– Next Steps:

And…

• Liaisons with each UC Team• Identify, across Use Cases:

– Use of Existing DESs– Need for New DESs

• Establish Path for DES to Template Ballot– DESs 38-40, 101-109– DESs “Below the Line”

• Full Drill down: Conceptual to implementable– DESs– Actions
