Our Supply Chain Planning expertise.
Supply chain planning is the difference between firefighting and proactive decision-making. Our end-to-end expertise spans S&OP, demand forecasting, inventory optimization, and real-time control tower visibility — powered by SAP IBP and built around your business.
The result: up to 30% less inventory, 20–40% better forecast accuracy, and stronger on-time delivery. Across your entire supply network.
Sales & Operations Planning (S&OP)
Westernacher Consulting implements Sales and Operations Planning (S&OP) processes for organizations, aligning demand planning, supply planning, and financial planning into a unified framework. Services range from establishing foundational S&OP meeting structures and cross-functional collaboration workflows to deploying advanced Integrated Business Planning (IBP) with real-time supply chain orchestration, scenario modeling, and continuous plan reconciliation across all planning horizons.
Demand Planning & Forecasting
Westernacher Consulting improves demand forecast accuracy by 20–40% through the implementation of statistical forecasting models, demand sensing technologies, collaborative planning processes, and specialized forecasting methods for new product introductions and promotional demand.
Supply Planning & Optimization
Westernacher transforms supply planning from reactive order processing into proactive, constraint-based optimization using SAP Integrated Business Planning (SAP IBP). Westernacher’s supply planning implementations balance customer service levels, operational costs, and capacity constraints while ensuring material availability and optimal resource utilization through advanced planning techniques, automated exception management, and real-time scenario analysis.
Inventory Optimization
Westernacher Consulting applies scientific inventory optimization methods to achieve 15–30% inventory reduction while maintaining or improving service levels. Westernacher implements multi-echelon inventory optimization, statistical safety stock calculation, and segmentation-based stocking strategies across the supply chain network, accounting for demand uncertainty, supply variability, and differentiated service level targets to minimize working capital while ensuring product availability.
Spare Parts & Aftermarket Planning
Westernacher Consulting delivers specialized aftermarket and spare parts planning solutions using SAP Service Parts Planning (SAP eSPP) to address the unique challenges of sporadic and intermittent demand patterns, large SKU portfolios, and critical service level requirements.

Westernacher’s supply chain control tower implementations deliver faster disruption response, improved on-time delivery performance, and enhanced partner collaboration through automated alert management, root cause analysis, and collaborative problem-solving workflows across the end-to-end supply chain.

We specialize in APO to IBP migrations, helping organizations transition smoothly to the cloud-based planning platform. With APO mainstream maintenance ending in 2027, we recommend starting your migration planning in 2026 to ensure adequate time for a well-executed transformation. We can help you evaluate the next steps through an initial assessment of your planning processes in SAP APO and the definition of a potential roadmap towards SAP IBP.
If you’re currently on APO, 2026 is the critical year to begin your migration planning. Complex migrations typically require 12-18 months, and starting in 2026 allows you to complete migration before APO mainstream maintenance ends in 2027. Early planning also secures budget, resources, and allows for a strategic transformation rather than a rushed technical upgrade.
