Traceability Scenario to Capability Mapping

The table below gives an initial assessment of capabilities required to enable the traceability scenarios, together with the mapping between capabilities and scenarios.

Enabling Capabilities T1 T2 T3 T4 T5 T6 T7 T8 Comments / Consequences
Ability to browse artefacts S2       S2       Ability to 'walk' a collection of artefacts (following axes as appropriate to siblings, children and parents, or by following links), irrespective of artefact type
Ability to create an arbitrary collection of artefacts   S1       S1 S1,2   Artefacts may be of any type
Ability to create, edit, delete, link and unlink requirement resources S6,7             S3  
Ability to create, edit, delete, link and unlink issue resources S3,8       S3,8       Need for additional 'issue' resource, or ability to subclass requirement resource
Ability to create, edit, delete, link and unlink supporting information / evidence resources S4 S7     S4       Need for additional 'supporting information' resource, or ability to subclass requirement resource
Ability to create, edit, delete, link and unlink argument resources S5       S5       Need for additional 'argument' resource, or ability to subclass requirement resource
Ability to create, edit, delete, link and unlink qualification case resources         S6,7       Qualification cases are a generalisation of test cases (i.e. there are more ways to assess qualification of an item than just testing it). This capability overlaps with the Quality Management domain.
Ability to create traceability graph resources   S1 S1 S1   S2 S3 S1,2 Need for additional 'traceability graph' resource, comprising a specific collection of artefacts (potentially of any type) and specific interconnecting links. Graphs may be defined by various combinations of: a. one or more 'starting artefacts'; b. one or more 'finishing artefacts'; c. one or more link types; d. link direction; e. number of traceability 'steps'; f. date of last modification
Ability to edit traceability graph resources by adding or removing artefacts and interconnecting links     S2,3     S3      

Column headings T1 to T8 refer to the eight scenarios, listed below. Step numbers in the table (S1, S2, etc) refer to the numbered steps in the associated scenario.

  • Scenario T1 - A requirement is elaborated?
  • Scenario T2 - A requirement is reviewed?
  • Scenario T3 - The impact of a change is assessed?
  • Scenario T4 - Requirements are traded?
  • Scenario T5 - Qualification activities are planned?
  • Scenario T6 - Qualification status is assessed?
  • Scenario T7 - A traceability report is generated?
  • Scenario T8 - Changes that affect a requirement are assessed?
