This document speaks to the FAST story - its goals, scope, structure, and process—while also summarizing FAST’s work.  The FAST Action Plan:

• Summarizes each recommended FAST solution
• Describes individual solution paths to implementation
• Communicates how the industry can get involved to help bring these solutions to implementation readiness and industry adoption

FAST convened panels of SMEs, in a series of 15 working sessions. SMEs were invited to participate based on their expertise in each area and came from various industry backgrounds, including healthcare, finance, and software development.
Discussions explored how each solution could be implemented most effectively, uncovered any remaining gaps and barriers that
need to be addressed, and gleaned other insights that could strengthen FAST solutions—as well as beginning to explore
potential paths forward.  Feedback collected from the SME Sessions was incorporated into the next versions of solution documentation.

The FAST community solicited industry feedback on both the architectural considerations and pathways to implementation for each of the proposed solutions.  Feedback collected from the workshop sessions was incorporated into the next versions of solution documentation.

FAST Tiger Teams shared initial drafts of their proposed solutions with the FAST TLC and the HL7 Community.  Feedback collected from those sessions was incorporated into the next versions of solution documentation.

The FAST Ecosystem Use Case Tiger Team was tasked to analyze a representative list of functional use cases developed by FHIR Accelerators and other HL7 Work Groups—from the perspective of

the ecosystem scalability needs and challenges.  Their analysis resulted in the identification of common ecosystem infrastructure challenges that most implementers might encounter, and the core capabilities required to overcome them.

Use cases for FAST were derived in one of 3 approaches:

1. Barrier Use Cases: Align use cases directly to an identified barrier such as endpoint discovery, security, and identity.
2. Healthcare Ecosystem Use Cases: Instead of aligning directly to a barrier, utilize industry ecosystem use cases which identify and spotlight barriers.
3. Functional Use Cases. Use functional use cases, such as Da Vinci, as a foundation for FAST. FAST provides the "highways" while the industry efforts, like Da Vinci, provide the cars, trucks, and buses. Uses the "vehicles" to help define the dimensions of the "highway."

FAST identified a series of technical barriers that needed to be addressed in order to scale FHIR as a ubiquitous technology that enables wide-scale clinical information exchange between providers, payers, and other stakeholders.
