# ConstraintFlow > ConstraintFlow is the operational intelligence layer for manufacturing. It connects > ERP, MES, WMS, spreadsheets, machines, and operational data, models a plant's real > constraints, and optimizes production decisions to improve throughput, reduce > scheduling complexity, and increase on-time delivery. Tagline: "Connecting Systems. > Optimizing Operations." ## What it does - Connects existing manufacturing systems (ERP, MES, WMS, spreadsheets, machines, workflows) into one unified operational model. - Sits ABOVE ERP and MES — it does not replace them. It adds the decision and optimization layer those systems were not built to provide. - Models real plant constraints: changeovers, machine capabilities, tooling, labor, materials, and sequencing dependencies. - Optimizes production scheduling, plant and machine allocation, order prioritization, and changeover reduction. - Detects bottlenecks before they reduce output and re-optimizes in real time as conditions change. - Provides an operational control tower with live status, constraints, and recommended actions for leadership. - Keeps humans in the loop: it proposes optimized, explainable options that planners approve, adjust, and commit. ## Who it is for Manufacturing operations leaders — COO, VP Manufacturing, VP Operations, Plant Director, and CIO/IT leaders. Built first for packaging manufacturers, with expansion into FMCG, pharma, and industrial manufacturing. ## Why packaging first Packaging combines frequent order changes, complex machine and tooling constraints, costly size/material/color changeovers, multi-plant decisions, and intense on-time delivery pressure — the operational complexity where an optimization layer delivers the most value. ## Business outcomes Improve throughput, reduce planning effort, reduce changeover waste, improve on-time delivery, increase plant utilization, and improve operational visibility. ## Deployment Cloud-native and enterprise-deployable — deploys into the customer's preferred cloud or enterprise environment, with automated setup designed for fast onboarding, enterprise security, and scale across multiple plants. ## Key pages - Home: https://constraintflow.ai/ - Platform: https://constraintflow.ai/platform - Packaging solution: https://constraintflow.ai/solutions/packaging - Production optimization: https://constraintflow.ai/solutions/production-optimization - Operational control tower: https://constraintflow.ai/solutions/control-tower - Blog: https://constraintflow.ai/blog - Contact / book a strategy call: https://constraintflow.ai/contact ## Contact Book a strategy call at https://constraintflow.ai/contact
