BIP3203 - Attachment G - CMMS Context Diagram.pdf

This file is an attachment (Attachment G) to the Illinois Department of Transportation (IDOT) CMMS RFP and contains a context diagram illustrating the Construction & Materials Management System (CMMS) and its interfacing systems. The diagram, dated August 18, 2025, depicts the CMMS as a central system that receives incoming contracts and financial data synchronization from the Electronic Letting Management (ELM) program, user identity data from the Employee Identification System (EID), and materials inspection and mix design data from the Materials Integrated System for Test Information and Communication Entry Program (MISTIC Entry). The CMMS provides data to multiple organizational entities and systems including Planning, Web-Based Motor Fuel Tax (WMFT), Fiscal Operations and Administration (FOA), Local Roads & Streets, Finance & Administration, Human Resources, Materials & Physical Research, and other systems. The diagram also indicates the presence of a mirrored database supporting the system architecture.

The context diagram serves as a technical specification component for IDOT's procurement of a commercial off-the-shelf SaaS-based solution to replace the existing CMMS. This visual representation establishes the integration requirements and data flow expectations that any proposed solution must support, demonstrating the system's critical role in IDOT's operational infrastructure and the complexity of integrations required for successful implementation and data conversion during the transition to a new platform.
