AI-Assisted System Design: Improving Sequence Diagrams Through Use Case Scenarios
Bibliographic record
Abstract
This paper explores two AI-driven approaches for transforming user stories (USs) into sequence diagrams (SDs). Pipeline A directly converts USs into SDs, while Pipeline B introduces an intermediate step of generating use case scenarios. Both pipelines leverage OpenAI’s GPT-4 model to automate these tasks. Ten user stories were processed through both pipelines and evaluated for accuracy, clarity, efficiency, and scalability. Pipeline B’s use of intermediate use case scenarios significantly improved the quality and detail of SDs while maintaining logical consistency and reducing ambiguity. These findings demonstrate the potential of AI-assisted tools to streamline software development, enhance collaboration, and make technical workflows accessible to non-technical stakeholders. While promising, challenges such as computational overhead and reliance on language models require further research. This study lays the groundwork for integrating AI into model-driven engineering, advancing efficiency and collaboration in software design.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
