Tools to Automate the S&I Platform A Proposal March 29, 2013 DRAF T

Growing Portfolio of Module Based Initiatives But this has led to growing complexity and diverse designs, models and solutions Doug Fridsma to HITPC – 3/14/13 13DRAFT

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 14DRAFT

Tools to Automate the S&I Platform USHIK Registry Reposito ry Link to NLM NIST Test Methods S&I Core Matrix UCAT IGAT Business Requirements and SMEs Implementable Solutions CEDD/FHIM/CIMI Data Models and Mapping Standards Developers and Stewards 15DRAFT

Why UCAT First? Foundational to all downstream automation and tools Highest leverage is at the beginning analysis and design of an initiative – COnstructive COst 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 DRAFT16

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. [BBC News, ] Chuck Shepherd’s News of the Weird, week of Dec 12, 2010

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

The Next Level

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

Today

Better Executable Verify >

Use cases Specify how user gets value from system Describe interaction of user & system Abstractly

Use cases Specify how user gets value from system Describe interaction of user & system Abstractly Ensure Verify Tests Concretely (specific test data)

S&I Simplification General 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 21 March 2013Simplification/UCAT Intro39

S&I Simplification Use 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) 21 March 2013Simplification/UCAT Intro40
