Phase 2 — Requirements engineering @ Bosch


📥 PRISM — Automated ReqIF Ingestion Engine

"The tool nobody talks about — but every requirements engineer desperately needs."

Problem Importing customer specification PDFs into IBM DOORS required up to 15 days of manual reformatting per project — error-prone, repetitive, and blocking every downstream activity
Solution Enterprise document transformation pipeline built on Azure Document Intelligence, with a dual-path extractor alongside PaddleOCR-VL → interactive React canvas block editor → concurrent export to three DOORS-compatible formats (RTF with OLE, HTML, ReqIF XML)
Key engineering ReqIF 1.2 compliance — full OMG spec with multi-tool targeting (DOORS Classic 9.x, DOORS Next/ELM, Polarion, Elektrobit) · • Two-tier automatic ReqID discovery — structural fingerprinting + frequency scoring, with meta-pattern regex fallback · • Three-tier heading inference — model → regex numbering → bbox height heuristic · • OLE COM pooling manager — process recycling to eliminate GDI handle leaks · • OCR result caching — immutable/mutable JSON split avoids re-running GPU inference on revisits · • Language filter — auto-discards non-English blocks from mixed content
Impact 15 days → ~3 days (80% cut) · 6,000+ pages processed · $30,163 USD cost avoidance · Currently in testing for worldwide enterprise release across Bosch

🔍 AI Requirement Similarity Assistant

"Stop re-inventing requirements that already exist in your legacy projects."

Problem Engineers manually compared incoming customer requirements against 10+ legacy project specifications — up to 15 days per review cycle, zero consistency
Solution ChromaDB-backed semantic search adopted across 10–15 European and North American OEM vehicle programs (Steer-by-Wire, EPS, Braking), built around a dual-path token saver: exact-string bypass at $0 LLM cost + embedding search for the rest — cutting API costs 40%
Key engineering 5-Gate self-improving prompt compiler — (1) statistical error pattern analysis on aggregated feedback, (2) LLM-designed prompt patch, (3) 4-check automated validation (stat backing, contradiction detection, shadow test on holdout set, confidence threshold), (4) human review, (5) canary deployment with deterministic 10% session routing and auto-promote/rollback · • Level 1 learning — feedback recall skips the LLM for previously-reviewed pairs (cosine ≥ 0.97) · • Per-user skill learning — extracts matching preferences from corrections, persists in SQLite, injects top-10 rules into the prompt
Impact 15 days → 5 days (65% cut) · $56,556 USD cost avoidance · 1,800+ engineering hours saved

🛡️ Agentic Safety Review Graph

"Catch what a rushed manual review misses — before it reaches the vehicle."

Problem Verifying safety-critical requirement attributes against ISO 26262 and SOTIF relied entirely on manual expert review — slow, and inconsistent under deadline pressure
Solution LangGraph multi-agent compliance verification graph combining specialized agents — Safety Standard Parser, ASIL Decomposition Auditor, Requirement Verifiability Checker, Safety Critic — with evaluator-optimizer loops
Impact >90% recall on safety-critical attributes, validated against certified functional safety experts · 60% faster review cycle
Tech LangGraph ISO 26262 ISO 21448 (SOTIF) Multi-Agent Evaluator-Optimizer
Status Award Winner · Internal enterprise specification honored with Bosch Engineering Excellence Award (July 2024)

🧠 Lumina RAG — Multimodal agentic enterprise search

"Ask your engineering documents anything — text, tables, drawings, audio, video."

Problem Engineers had no unified way to query across heterogeneous document types (PDFs, drawings, audio meeting notes, video recordings) to verify functional safety requirements
Solution Corrective RAG (CRAG) pipeline orchestrated by LangGraph with 5 agents — Router → Retriever → Grader → Rewriter → Generator. Self-correcting loops rewrite and re-retrieve (HyDE, step-back, decomposition) whenever retrieved context is irrelevant
Key engineering Multimodal ingestion — PDF/DOCX/PPTX (Docling OCR + table extraction), audio (Groq Whisper-large-v3), video (ffmpeg keyframe extraction + VLM captioning), images (PyMuPDF + VLM) · • Hybrid vector search — Qdrant dense + BM25 sparse with RRF fusion, followed by an NVIDIA reranker · • Content safety — NVIDIA NemoGuard 8B pre-screens all queries · • FastMCP server — exposes indexing and search as standard Model Context Protocol tools via SSE · • 298 automated tests across the pipeline

⚙️ PDI Workbench — Platform Design Intelligence

"What if I change the torsion bar diameter from 9mm to 10mm? — answered in seconds, not days."

Problem Impact analysis of design changes required consulting multiple disconnected specification documents, with knowledge scattered across teams
Solution Hybrid agentic pipeline: entity extraction → Neo4j knowledge-graph multi-tool query (11 tools) → sufficiency check → scoped ChromaDB vector search (4 tools) → Claude Sonnet synthesis with extended thinking. 12 granular SSE event types stream reasoning steps live
Key engineering Cytoscape.js renders Neo4j traversal paths as interactive graph visualizations · • Plotly.js projects vector search results as 2D PCA cluster scatter plots · • Versioned prompt system — 8 purpose-specific prompts · • Drawing OCR — Gemini API extracts structured data from engineering drawings with sufficiency scoring · • Dual-run tolerance stack engine — flags radial clearance violations flipping PASS to FAIL
