1 Introduction (1/3)

When using the RUP, goals are captured in

the Vision Document (Text based)

Once defined, goals in the Vision Documentare refined & captured in additional models. E.g. functional goals -> Use Case Diagrams

non-functional goals -> Special Requirements section of the

use cases

1 Introduction (2/3)

Problem :RUP does not provide any guidance on how

to create the traceability matrix.

Solution : Their work provides a specific approach to

defining these traceability relationships.

QARAT is used to illustrate this approach.

1 Introduction (3/3)

Quality Assurance Review Assistant Tool

(QARAT) Supports capturing & managing the results of

conducting quality assurance inspections, or

reviews, of various SE artifacts.

Reviewer can conduct their inspections remotely

& submit their comments, defects identified.

4 Refining Functional & Non-

functional Goals into Use Cases (1/7)

Refining Functional Goals into Use Cases

3. Straightforward refinement of each leaf of the goal model into

one Use Case(1:1)

- Disadvantage : does not allow for defining Use Cases that mergeor split various goals

4. Flexible refinement of a goal into one Use Case- many goals combined into one Use Case, and/or a goal split into

many Use Cases(N:M)

Refining Non-functional Goals into Use Cases

Allows a N:M mapping

For each goal in the decomposition, the analyst identifies the

Use Case(s) it applies to.

5 Conclusions

Integrate functional & non-functional visual

goal models into the RUP

Intuitive visual presentations in addition to the

textual representations can provide more

detail requirements
