OHCS-GHANA/Intelligent-Integration-Engine

Process intelligence for OHCS (Ghana): one unified event log mined into the real process map, bottlenecks, conformance findings and decision support. Cloudflare Workers + D1 + Workers AI + Vectorize + React. # IIE — Intelligent Integration Engine > Process intelligence for the Office of the Head of Civil Service (OHCS), Ghana. > One unified event log from every subsystem — RFID attendance, the leave > workflow, and an HR chatbot — mined automatically into the real process map, > bottlenecks, conformance findings, and management-ready recommendations. **Open the live demo →** — passwordless sign-in with 6-digit OTP. 11 test accounts cover every RBAC role from Employee to System Admin, seeded with 6 months of simulated OHCS operations (150 staff across the 9 real OHCS units, ~33,300 events). Explore the four views — Operations, Process Intelligence, Decision Support, and My Leave — plus the floating AI assistant. ## What is this? Most dashboards show you numbers you asked for. IIE discovers how work *actually* flows from the event log and tells you where reality deviates from policy — without anyone configuring it: - The process map below was **mined, not drawn** — it discovered both real OHCS leave chains (standard leave via F&A, study leave via RTDD) from raw events alone. - It flags the slowest hand-off (supervisor → F&A verification, median 3.3 days) and catches every case that bypassed supervisor review (22/22, zero false positives) — validated against planted ground truth. ## Highlights - **Unified canonical event log** — every subsystem emits one event schema; new systems just start emitting. - **Process discovery** — directly-follows graph mining with variants, per source system. - **Bottleneck detection** — median/P95 transition times vs per-source SLA thresholds (KV-tunable, no redeploy). - **Conformance checking** — every leave case audited against the prescribed chain for its type. - **Decision support** — severity-ranked, plain-English recommendations + department comparison, exportable to CSV/PDF. - **Self-service leave** — submit/track/approve through the real OHCS chains; the state machine enforces role *and* directorate. - **AI assistant** …
