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?
