Unifying Production and Material Planning with Purpose-Built Software

A Fortune 500 manufacturing company used an enterprise ERP platform to generate work orders for multiple production lines at one of its facilities. While the ERP accurately identified what needed to be produced, the resulting work orders weren't always sequenced efficiently. With thousands of product models and configuration differences, poor sequencing increased changeovers, extended setup time, disrupted material consumption, and reduced line utilization.
Prism Systems built an integrated production and material planning platform that let plant personnel optimize the ERP-generated schedule using facility-specific rules, while giving material analysts near-real-time visibility into inventory, purchase orders, and supplier deliveries, all connected to the company's existing ERP environment.

The Challenge
The corporate ERP generated work orders based on enterprise-wide requirements, but didn't account for plant-level constraints like manufacturing-line capabilities, shift schedules, planned downtime, line capacity, product-family sequencing, and changeover rules. With thousands of possible sequences, manually arranging work orders was time-consuming and inconsistent.
Rearranging the schedule also shifted component demand, and analysts needed to know whether inventory and incoming deliveries could support it. Because the process depended on daily ERP updates, shortage visibility was often delayed, leaving little time to adjust orders or coordinate with suppliers.
The Solution
Prism Systems developed a plant-level scheduling and material-planning application that extended the ERP system without replacing it. It imported work orders, schedules, bills of material, inventory, purchase orders, and supplier data from the enterprise platform, then combined that with plant-specific data such as calendars, shift schedules, line capacity, model compatibility, and changeover rules.
Using this combined data, the application generated an optimized production sequence to reduce changeover time while meeting volume and delivery commitments. Schedulers could review, adjust, and evaluate the sequence before finalizing it.
Production Schedule Optimization
Rather than treating work orders independently, the engine evaluated relationships between adjacent orders, grouping similar products and minimizing costly transitions. It weighed constraints like line capability, available time by shift, maintenance windows, production rates, changeover time, and delivery priorities. Schedulers retained control, moving or reprioritizing orders as needed, and the approved sequence flowed back to the ERP system.
Material Availability Analysis
The application expanded each work order through its bill of material and calculated component demand against on-hand and allocated inventory, open purchase orders, confirmed supplier quantities, and expected delivery dates. This gave analysts a time-phased view of availability, showing exactly when a shortage would occur, rather than just whether one existed currently. It distinguished current shortages from projected ones, late or insufficient purchase orders, misaligned deliveries, and excess inventory.

Near-Real-Time Shortage Visibility
The platform recalculated material requirements whenever a schedule changed, without waiting for the next ERP planning cycle. Analysts could immediately see which work order created new demand, review affected components, locate related purchase orders, compare delivery dates, and contact suppliers to adjust commitments, sharply shortening the time between spotting an issue and resolving it.
Purchase Order and Supplier Coordination
When schedule changes shifted a component's required date or quantity, analysts could review purchase orders and write approved changes back to the ERP in near real time, so suppliers could be notified of revised dates, quantities, or priorities, aligning commitments with actual plant production.
Integrated ERP Data
The ERP remained the system of record for work orders, schedules, bills of material, inventory, purchasing, and supplier data. Rather than duplicating ERP functionality, the application added a specialized planning layer, exchanging data bidirectionally so approved changes flowed back into the enterprise system.

Unified Workflow
Production schedulers used the platform to review ERP work orders, build optimized sequences, apply plant rules, balance lines, and submit approved schedules back to the ERP. Material analysts used the same schedule to validate inventory, identify shortages, assess purchase-order coverage, and coordinate supplier changes, keeping both groups synchronized.
Business Benefits
Reduced changeover time through smarter product grouping
Faster shortage detection via near-real-time recalculation instead of daily cycles
Improved schedule feasibility by weighing capacity, shifts, and material readiness upfront
Better supplier alignment through updated purchase-order quantities and dates
Increased planner productivity by consolidating planning, purchasing, and supplier data into one workflow
Greater responsiveness to changes in demand, capacity, or supply
Preserved ERP investment, extended rather than replaced
Conclusion
Enterprise ERP systems coordinate production across large organizations, but individual plants often need more detailed scheduling logic than a corporate system can provide. Prism Systems' platform bridged that gap, combining enterprise data with plant-specific rules to turn a general production plan into an optimized, materially feasible schedule, giving schedulers greater control and analysts earlier visibility into shortages.
