1. Why Requirements Traceability? Applications development may take several months to years... Staff transition takes away business requirements background and knowledge Requirements traceability metamodel enables: traceability provides assurance of requirements being current requirement not lost and is being addressed Provides systematic method to analyze and maintain requirements lineage Baba Piprani, Marlena Borg, Josée Chabot, Éric Chartrand, 12 Nov 2008, Monterrey An Adaptable ORM Metamodel to Support Traceability of Business Requirements across System Development Life Cycle Phases

1. Why Requirements Traceability? - Benefits for Organization: Provides continuity promotes good data governance protection of corporate memory Increased stakeholder confidence in IT shop Increased productivity of project staff Increasingly contributes towards meeting objectives and plans Baba Piprani, Marlena Borg, Josée Chabot, Éric Chartrand, 12 Nov 2008, Monterrey An Adaptable ORM Metamodel to Support Traceability of Business Requirements across System Development Life Cycle Phases

1. Why Requirements Traceability 1. Why Requirements Traceability? - Benefits for Business Client or Stakeholder: Eliminates or reduces time and effort to completely explain or rationalize requirements Improve confidence in systems development process and the final product will be fully reflective of their needs Enables scope management instead of scope creep Improve confidence in system output results Baba Piprani, Marlena Borg, Josée Chabot, Éric Chartrand, 12 Nov 2008, Monterrey An Adaptable ORM Metamodel to Support Traceability of Business Requirements across System Development Life Cycle Phases

1. Why Requirements Traceability? - Benefits for System Developer: Requirements would be documented in one place...thus Reducing time and effort required to analyze requirements Efficiently track the requirements Eliminate need to repeat or locating requirements during project staff transition or lengthy delay between phases Quickly identify conflicting or redundant requirements Facilitate accurate verification that requirement has been addressed Baba Piprani, Marlena Borg, Josée Chabot, Éric Chartrand, 12 Nov 2008, Monterrey An Adaptable ORM Metamodel to Support Traceability of Business Requirements across System Development Life Cycle Phases

Harmonizing the Business Requirements to the SDLC Model Suite Many SDLCs typically have a separate requirements collection phase along with identified deliverables… Search for the Holy Grail….hoping to receive a Wal-Mart style packaged set of requirements! Hah! Enterprises usually start of in earnest with some kind of usable methodology…Use Cases, Functional Requirements doc, etc… Ends up in some divorced system development incarnation that is non-reflective of the specifications Business rules are buried somewhere in the code, with redundant code modules, totally missing business rules…etc….

Reality of Business Requirements… Accumulate over several years in the form of e-mails, meeting minutes, memos, reports, consultant studies etc… In TC Transportation of Dangerous Goods Inspector Information System, we had over 150 docs over 10 years reflecting the business requirements as noted above… We needed to use what we had and not re-invent the wheel (Hey…as a consultant, I am not complaining if we went to re- invent the wheel!---but being down-to-earth, why go dejavu…?) The ORM Metamodel for Business Requirements was born, based on collected documents… Baba Piprani, Marlena Borg, Josée Chabot, Éric Chartrand, 12 Nov 2008, Monterrey An Adaptable ORM Metamodel to Support Traceability of Business Requirements across System Development Life Cycle Phases

Summary Business requirements traceability metamodel provides the much required requirements lineage Captures all facets and incarnations of business requirements “as-they-happen…” Metamodel enables tracking of documents, tracking of actual requirements---projected into the realization and implementation of the stated requirements Metamodel allows navigability across multiple models involved in the SDLC, and supports the zig-zag or other development processes The requirement propositions have been ‘lobbed’ over to the user’s court for verification!
