The SIOP Manager   is responsible for   building a world-class, data-driven Sales, Inventory & Operations Planning (SIOP) process by integrating direct demand signals from key customers and strategic distributors into the ERP planning system. Reporting to the Supply Chain leadership, this role serves as the business owner for the SIOP process and the Infor LN SIOP module implementation.  

Unlike a traditional demand   planner focused on forecasting internally, this role will   establish   collaborative planning with customers, measure forecast accuracy and create a closed-loop continuous improvement process that increases visibility, inventory productivity, and service levels.  

The   objective   is to transform planning from internally generated forecasts into a collaborative, technology-enabled process supported by ERP automation and real-time demand intelligence.  

Key Responsibilities  

• Lead the implementation and continuous   improvement of the Infor LN SIOP module.  

• Develop and   maintain   the monthly SIOP process across Sales, Supply Chain, Operations, and Finance.  

• Establish direct demand planning collaboration with key customers and top distributors.  

• Collect,   validate , and integrate customer demand signals into the ERP planning system.  

• Create a formal closed-loop process that measures forecast accuracy by   customer   and   distributor   and provides regular feedback to improve future planning.  

• Develop dashboards and KPIs to   monitor   forecast accuracy, bias, inventory impact, and service performance.  

• Partner with IT and ERP teams to implement enhancements, automation, and system improvements.  

• Standardize planning assumptions, master data governance, and planning parameters.  

• Identify   gaps between customer forecasts and actual demand and drive corrective actions.  

• Facilitate monthly SIOP meetings, including but not limited to Executive SIOP   meeting , by presenting demand trends, risks, and recommended actions.  

• Support inventory optimization   by improving forecast quality and planning discipline.  

• Work cross-functionally with Sales, Operations, Purchasing, Finance, and IT to improve planning capabilities.  

• Lead continuous improvement initiatives that simplify processes and reduce manual work.  

Required Skills & Competencies  

Technical Skills  

• Strong understanding of SIOP, demand planning, and supply chain processes.  

• Experience implementing or administering ERP planning modules (Infor LN preferred; SAP, Oracle, or similar acceptable).  

• Advanced   analytical and statistical forecasting capabilities.  

• Strong knowledge of inventory planning and replenishment principles.  

• Experience building dashboards and KPIs using Excel, Power BI, or similar tools.  

• Ability to translate business requirements into system enhancements with IT teams.  

• Understanding of   data integration and automated planning workflows.  

Leadership Competencies  

• Process-oriented with a continuous improvement mindset.  

• Strong project management and implementation skills.  

• Ability to influence   cross-functional teams without direct authority.  

• Excellent communication and presentation skills.  

• Customer-focused and collaborative.  

• Data-driven decision   maker   who   challenges   assumptions with facts.  

• Strong change management capabilities.  

Preferred Experience  

• 5+ years of experience in SIOP, Demand Planning, Supply Chain, or Integrated Business Planning.  

• Experience implementing ERP planning modules or planning systems.  

• Manufacturing environment experience preferred.  

• Lean or Six Sigma experience is a plus.  

• Experience collaborating directly with large customers or distributors on demand planning.  

Success Measures  

The successful candidate will deliver measurable improvements through:  

• Successful implementation and adoption of the Infor LN SIOP module.  

• Increased forecast accuracy from key customers and distributors.  

• Monthly forecast accuracy scorecards shared with demand providers.  

• Closed-loop   planning process that continuously improves forecast quality.  

• Reduced inventory while   maintaining   or improving service   levels.  

• Improved production stability through better demand visibility.  

• Increased automation and reduced manual planning activities.  

• Establishment of a collaborative planning culture between customers, distributors, Sales, Supply Chain, and Operations.  

Critical Success Mindset  

This role is less about creating forecasts and more about building a planning system. The ideal candidate thinks like a process architect— leveraging   technology, analytics, and customer collaboration to create a self-improving SIOP   process where better demand signals lead to better operational decisions.
