PartsOS Planning
How Weinig AG used PartsOS Planning to reduce manual planning effort by 85%, increase spare parts availability by 30%, and cut the order backlog by 56%. Step by step, without interrupting ongoing ERP projects.
Reduction in manual planning effort in spare parts management
Increase in spare parts availability in mechanical engineering
Reduction in order backlog through AI-powered inventory planning
Weinig AG is a globally leading manufacturer of machines and systems for solid wood and wood-based panel processing. With approximately 2,500 employees and multiple independent business units, Weinig is a prime example of industrial mechanical engineering at the highest level. Yet this very size and structure became the root of a serious problem in spare parts planning.
Different business units operated with different planning and procurement methods.
The result: redundant inventories, unclear responsibilities, and a lack of transparency regarding which parts were held where and in what quantities. While certain spare parts were unavailable when needed and customers waited on deliveries, excess stock was piling up elsewhere, with significant write-off risk.
Key pain points before PartsOS:
Using PartsOS Planning, Weinig introduced SKU-specific demand forecasting. Instead of flat-rate safety stock buffers, the system calculates individually for each part number: What is the historical demand? How volatile is it? What safety stock level is data-justified?
In addition, a dynamic stockflow calculation was introduced that continuously reconciles inventory and demand signals and automatically generates order recommendations.
Phased Rollout without Disrupting Ongoing Projects
Since Weinig was running parallel ERP transformation projects, a smooth, incremental implementation approach was critical. PartsOS Planning was rolled out business unit by business unit, starting where the pain was greatest. For each step, an individual integration roadmap was developed to ensure synchronization with the ongoing ERP projects.
The implementation was carried out in close, collaborative partnership, methodologically and functionally, not as a pure IT project.
Planning and Procurement Strategy Fundamentally Redesigned
Beyond the tool itself, the entire procurement strategy was rebuilt on a data-driven foundation. Procurement parameters, minimum stock levels, and supplier strategies were calibrated based on actual demand history, no longer on experience-based assumptions or flat-rate markups.
Improvements are measurable across all three original pain points:
Manual planning effort: −85%
Spare parts availability: +30%
Order backlog: −56%
The automation of planning and procurement processes has significantly reduced manual workload. AI- and ML-powered inventory control minimizes both overstock and shortages, simultaneously, not as a trade-off.
“PartsCloud is a strategic partner for us. Together, we are defining the path toward a modern spare-parts planning approach - with the goal of reducing manual processes and improving availability. What we value most is the collaboration itself: highly competent, pragmatic, collaborative, and rooted in a genuine understanding of mechanical engineering.”
Head of Lifetime Services
With parallel ERP transformation projects already underway, Weinig needed a solution that could be integrated without an IT project and deliver immediate value. PartsOS Planning was connected to the existing ERP without any add-on or reimplementation and was live within days.
Weinig AG faced a classic planning dilemma in mechanical engineering: excess inventory in some business units, simultaneous stockouts in others, high manual planning effort, and a lack of cross-unit inventory transparency, all while running parallel ERP transformation projects that could not absorb additional IT complexity.
Since go-live in February 2026, Weinig AG has achieved: −85% in manual planning effort, +30% in spare parts availability, and −56% in order backlog, measurable across all three original pain points simultaneously, not as a trade-off.
PartsOS Planning calculates individually for each part number: historical demand, volatility, and the data-justified safety stock level. Instead of blanket safety buffers, every SKU receives a tailored planning strategy, consistent and transparent across all business units and locations.
