  1. TRACEABILITY BETWEEN SOFTWARE SYSTEMS AND SOFTWARE MODELS Presented by Vinay Gunnam

  2. What is “Traceability” ? • The IEEE Standard Glossary of Software Engineering Terminology defines traceability as “the degree to which a relationship can be established between two or more products of the development process, especially products having a predecessor-successor or master-subordinate relationship to one another.”

  3. Why is “Traceability” needed ? • Frequent changes in requirements • Software design turning more complex • Reduction of cost of software development • Enhance the software development cycle

  4. Directional Traceability FORWARD  Is the requirement implemented ? BACKWARD  Is the implementation required ?

  5. Features of a Traceability Technique • bidirectional requirement linking to system elements • capture of allocation rationale, accountability, and test/validation • identification of inconsistencies • capabilities to view/trace links • verification of requirements • history of requirements changes

  6. Traceability Techniques • Cross Referencing (tagging, numbering, indexing, track matrices) • Templates and Integration/Transformation documents • Restructuring • Automated/Semi-automated methods were also developed

  7. Example: Track Matrices

  8. Drawbacks of Traceability • Lack of a common definition • Conflicting underlying problems • Coarse granularity of traceable entities • Immature integration technology • Project longevity
