© CDISC 2014 SHARE TA RC Pilot SHARE TA RC Pilot: Bringing together the TA Project RC experience with the SHARE Approach to RCs to streamline and simplify the TA development process 2 CFAST TA Development Process Concept Maps and components SHARE Metadata display tables for 2 Tas Diane’s updated Metadata display tables. ISO based SHARE Metamodel NCI Concepts already in SHARE as building blocks for RCs Additional Information Science / Business Analysis Best Practices Research Concepts from other sources (Roche, Lilly) TA Project Experience with RCs SHARE Approach to RCs SHARE TA RC Pilot Top Down (from Concept Maps) Bottom Up (from Existing Standards)

© CDISC 2014 Current SHARE Thinking on RCs 3 Semantics Manager provides the place to house the RCs, but not the mechanism to develop RCs (Semantics Manager can do it, but its not really built for RC development). This pilot will aim for RC alignment with BRIDG rather than creating RCs starting with BRIDG (using a BRIDG-instantiated tool) since we already have experience with the BRIDG-instantiated approach (and we have candidate solutions that would work, e.g. ADL Workbench). This pilot will give us more knowledge about how SHARE will source and use RCs and what they look like in Semantics Manager

© CDISC 2014 What are RCs? Working Definition ISO Definition: A Concept is a unit of knowledge created by a unique combination of characteristics.  In general, for CDISC: Research Concepts are high-level building blocks of clinical research information that encapsulate lower level implementation details like variables and terminologies.  For SHARE: A research concept is a unique combination of SHARE Concepts and Rules that define the independent units of knowledge found within each CDISC class. 7

© CDISC 2014 Research Concepts are Hard to Define Wiki page: Definitions for Research Concepts  A quick review turned up about 15 proposed definitions Many attempts to define RCs include descriptions of a solution  Disparity in opinions on how RCs should be created is reflected in the definitions The breadth of RC scope has made a simple definition difficult  IMO, the lack of complete CDISC standards model, including the Conceptual Layer, confounds the ability to define RCs  RCs represent multiple parts of the CDISC model 8

© CDISC Support TA Standards Development Support the TA projects in developing concept-based standards for all new projects by early 2015  Faster, more effective way to develop TA standards  Development of standards that are consistent with the CDISC Model Enable SMEs to work with conceptual representations of the standards represented using natural language  Communicate without using the structural metadata (e.g. SDTM domain structures and variables) Support C-Map templates  Provide re-usable concepts as C-Map templates 9

© CDISC Support TA Standards Development Provide a methodology for transforming conceptual models into structural models  Process for converting conceptual models to structural models that represent standards like CDASH and SDTM  Include a process for verifying the conceptual models Represent clinical phenomena using a combination of Concepts and associated Rules  Using ISO
