Attachment G Context Level Diagram B-50780.xlsx

This file is a Context Level Diagram for the Aeronautics Program Management System (APMS) RFP issued by the Illinois Department of Transportation (IDOT) Division of Aeronautics. The diagram illustrates the system architecture and data flows for the proposed NCR Payment System, which serves as the in-scope centerpiece for this initiative. The system interfaces with multiple existing platforms including the ELM Letting Management System, Fiscal Operation and Administration System (FOA), Aero Program Management Application, CMMS warehouse, SAP HPPR, and FAA systems (ADIP and Delphi). The diagram was approved on January 16, 2025, by Project Manager Alex Batten, Solution Architect Colin D. Blair, and EPMO Manager Becky J Motor, indicating the project had progressed to an advanced planning stage at that date.

The context diagram identifies key data exchanges and system touchpoints necessary for the new system's operation. Data flowing into the NCR Payment System includes grant payment information, payment requests, airport data, awarded contract details (aircraft and pilot certification information), and waiver information from the FAA systems. Outgoing data from the payment system comprises payment data in the form of vouchers and warrants, along with associated object codes, schedule numbers, obligation numbers, voucher numbers, and warrant numbers. The solicitation includes a Disadvantaged Business Enterprise (BEP) goal of 2%, indicating a commitment to small business participation in this modernization effort to replace the agency's existing databases and processes.
