How Better Demand Planning and Production Visibility Reduced Inventory, Improved Customer Service, and Increased Productivity
For manufacturers, operational performance begins long before production starts. When demand visibility is limited, production schedules become reactive, inventory levels fluctuate, customer service suffers, and operations teams struggle to maintain efficiency. Even organizations with strong scheduling capabilities can find themselves constantly firefighting when they lack visibility into future demand. This was the challenge facing Nellson.
According to Craig Young, Senior Director at Nellson LLC, the company wanted to improve its ability to see customer demand further into the future, translate that demand into an executable production plan, and create a consistent operational rhythm across the business. Leadership recognized that better visibility and planning would lead to stronger operational performance while also improving customer service, inventory management, and working capital. To achieve these objectives, Nellson partnered with LMA Consulting Group to strengthen SIOP (Sales Inventory Operations Planning) processes, improve planning visibility, enhance ERP utilization, and create a more integrated approach to demand, supply, and production and materials planning.
Looking Beyond Scheduling
Nellson already had solid finite scheduling practices in place. However, leadership recognized that scheduling alone was not enough. Without a structured process to understand customer demand several months into the future, production plans often became reactive. As demand shifted, the organization was forced to make adjustments that impacted inventory levels, customer service, and manufacturing efficiency.
LMA began by listening. The team met with stakeholders across scheduling, inventory management, warehouse operations, procurement, production, and supply chain leadership to understand how information flowed throughout the organization and identify opportunities for improvement. The objective was not simply to improve one department. The goal was to create visibility and alignment across the entire supply chain.
Creating Visibility Through SIOP
One of the most impactful initiatives was the implementation and strengthening of the SIOP process. The organization needed greater visibility into customer demand so that it could proactively plan production, materials, labor, and capacity requirements. LMA helped establish a structured planning process that extended visibility from a matter of weeks to several months.
This improved visibility enabled the company to:
- Better understand future customer demand
- Improve forecasting and planning accuracy
- Align production schedules with expected requirements
- Improve the use of their advanced planning system (APS) tool
- Increase MRP effectiveness
- Identify potential capacity constraints early
- Create more stable manufacturing schedules utilizing the production wheel concepts
The result was a more proactive approach to planning and decision-making throughout the organization.
Turning Demand into an Executable Production Plan
Visibility alone does not improve performance. The real value comes from translating demand information into operational decisions. Through the SIOP process, customer forecasts and demand signals were converted into production plans that could be executed effectively across the business. As visibility increased from two weeks to one month, two months, and ultimately several months into the future, the organization gained the ability to smooth production requirements and reduce variability. This created a more predictable production environment and a stronger operational rhythm throughout the facility.
For co-manufacturers, operational rhythm matters. Consistent production schedules improve labor planning, increase equipment utilization, reduce disruptions, minimize waste, and support overall manufacturing efficiency.
Improving Inventory and Working Capital
As planning processes improved, inventory performance improved as well. The company evaluated purchasing practices, minimum order quantities, supply and demand relationships, and ERP utilization to better align inventory with actual requirements. LMA worked directly with buyers and planners to improve both processes and capabilities. Rather than simply implementing recommendations, the team focused on developing employee knowledge so improvements could be sustained long after the engagement concluded.
The results were significant. Inventory levels were reduced by approximately 50%, freeing working capital while improving inventory management practices throughout the organization.
Strengthening Customer Service
Improved planning and production visibility also had a direct impact on customer service. As schedules became more predictable and planning processes matured, the organization improved its ability to deliver customer orders consistently and on time. On-time-in-full (OTIF) performance improved from the low 90% range into the high 90% range. For a contract manufacturer, these improvements represent more than operational metrics. They strengthen customer relationships, improve reliability, and support future growth opportunities.
Recovering Value Through Better Data
Another important outcome involved inventory accountability and cost recovery. Historically, the company had limited visibility into customer-specific inventory commitments and material consumption. As planning processes improved and data became more accessible, the organization developed stronger documentation and traceability regarding customer requirements and inventory usage. This created the ability to recover costs associated with expired and unused inventory that previously went unbilled. The result was a meaningful financial benefit and another example of how better data visibility drives stronger business performance.
The Results
By improving demand visibility, strengthening SIOP processes, and creating a more disciplined planning environment, Nelson established a stronger operational rhythm throughout the organization.
This improved operational performance in several ways:
- Greater visibility into customer demand
- More effective production planning and scheduling
- Improved manufacturing efficiency and productivity
- Better labor utilization
- Increased schedule stability
- Stronger MRP effectiveness
- Improved decision-making across the organization
These operational improvements also generated significant business results:
- Inventory reduced by approximately 50%
- Significant working capital improvements
- OTIF performance improved from the low 90% range to the high 90% range
- Improved customer satisfaction
- Increased recovery of expired and unused inventory costs
- Enhanced ERP utilization and employee capabilities
Most importantly, the organization moved from reacting to short-term demand changes to proactively planning several months ahead. This visibility created the operational stability necessary to support stronger performance across manufacturing, inventory management, and customer service.
Building Sustainable Operational Excellence
Successful supply chain transformation is not simply about improving metrics. It is about creating processes, visibility, and organizational capabilities that continue delivering results year after year. By improving demand visibility, strengthening SIOP processes, enhancing ERP utilization, and developing internal capabilities, Nellson created a foundation for stronger operational performance and long-term growth.
