Tools to Automate the S&I Platform A Proposal March 29, 2013 DRAFT
Growing Portfolio of Module Based Initiatives But this has led to growing complexity and diverse designs, models and solutions DRAFT Doug Fridsma to HITPC – 3/14/13
S&I Core Matrix Has Captured and Standardized S&I Initiatives . . . . . . as Shared, Reusable and Computable Components . . . Now we need a tool to use the Core Matrix DRAFT
Tools to Automate the S&I Platform • S&I • Core Matrix • UCAT • IGAT Business Requirements and SMEs • USHIK • Registry • Repository • Link to NLM • NIST • Test Methods Standards Developers and Stewards CEDD/FHIM/CIMI Data Models and Mapping Implementable Solutions DRAFT
Why UCAT First? • Foundational to all downstream automation and tools • Highest leverage is at the beginning analysis and design of an initiative • COnstructiveCOst Model – Overall effort is doubled if analysis is shortchanged • Correct is hard... but easier than later fix • Ounce of prevention • Measure twice, cut once • “By failing to prepare, you are preparing to fail” Ben Franklin • Use Cases • Study how users get value from system • Define how users interact with system • Help subsequent efforts deliver value • Are contracts between users & developers • Refer to Art Griesser Presentation in Appendix DRAFT
Use Case Authoring Tool DRAFT
NIST Role (Kevin – maybe quotes from Frederick • Experience with Use Case Authoring through Smart Grid • Developed automated test procedures, methods and tools for CEHRT and Mod Specs • UCAT is based on NIST platform with further specialization for the S&I Core Matrix by Art Greisser DRAFT
UCAT Demonstration • NEED OUTLINE FROM ART • Show how to create a human readable, machine computable UC example from Core Matrix and UCAT DRAFT

COnstructive COst MOdel Effort is Doubled if analysis is shortchanged
Why Is Analysis So Important? • Correct is hard... but easier than later fix • Ounce of prevention • Measure twice, cut once • By failing to prepare, you are preparing to fail Ben Franklin
Police in Gumperda, Germany, arrested a 64-year-old retired do-it-yourselfer in November after he drilled through a neighbor's wall in their duplex home. The man had spent two days trapped in his own basement, where he had laid bricks and mortar for a room but apparently forgot to leave himself an exit.

Use cases... • Study how users get value from system • Define how users interact with system • Help subsequent efforts deliver value • Are contracts between users & developers
UML? • Suitable for parts of a use case: • Use case diagram • Activity diagram • Communication diagram • Usually a small fraction of a use case • UML does not define use case structure
Beware • Analysis Paralysis • Duplication • Conflicting Requirements • Excessive Complexity
What if... • We could just “run” use cases as tests? • Traceability guaranteed • Tests & use cases always in synch • Less effort, expense • Tests are as complete as use cases
Better Today Executable Verify >
Use cases • Specify how user gets value from system • Describe interaction of user & system • Abstractly
Use cases Tests • Specify how user gets value from system • Describe interaction of user & system • Abstractly Ensure Verify Concretely (specific test data)
S&I SimplificationGeneral High Level Goals • [G1] Decrease | limit waste • Time spent working on artifacts • Unused or unreachable artifacts • [G2] Increase domain penetration • The more use cases and scenarios, the more fully the domain issues can be understood and addressed • [G3] Centralize information • Create a network of specialized information that can be shared • [G4] Increase | facilitate collaboration • Manage centralized information so it stimulates collaboration (i.e. online services) • [G5] Facilitate integration of information in process • Information generated at a point in the process should flow and be easily usable by underlying processes • [G6] Reuse of existing infrastructure Simplification/UCAT Intro
S&I SimplificationUse Case Authoring Tool • Facilitates use case components capture (G1-2) • Facilitates use case components reuse (G1-2) • Creates a repository of use case components (G3) • Is accessible online (G4) • Allows for developed use cases to be electronically handled by underlying processes (i.e. implementation guides) (G5) • Helps the developed use cases to stay consistent (G1-3-5) • Allows full access of the underlying data to trusted members for integration with the existing infrastructure (G6) Simplification/UCAT Intro
