Core Responsibilities

Primary Functions

  • Develop and own SKU-level demand forecasts and inventory plans for assigned categories using historical sales, trend analysis, promotional calendars, seasonality adjustments, and market intelligence to meet service level and margin objectives.
  • Create and maintain cadence-based replenishment plans (weekly/monthly) using ERP/MRP systems and automated planning tools, translating forecasts into purchase orders, allocation plans, and transfer recommendations.
  • Collaborate with merchants to build assortment strategies, product lifecycle plans (introduction, replenishment, clearance), and launch/phase-out schedules that align with merchandising goals and space constraints.
  • Set and monitor target inventory metrics (turns, sell-through, weeks of supply, cover) and drive actions to correct deviations through reorders, price/promotional recommendations, or inventory transfers.
  • Manage promotional planning and event forecasting, coordinating with marketing and category teams to model lift, cannibalization, lead time changes, and temporary allocation strategies.
  • Conduct SKU rationalization and lifecycle analysis to identify slow-moving SKUs, propose consolidation or discontinuation, and recommend clearance strategies to reduce carrying costs and free up working capital.
  • Partner with supply planning and vendor management to negotiate lead times, minimum order quantities, and production schedules, ensuring alignment between commercial plans and supply capacity.
  • Monitor and report on forecast accuracy, bias, and variance at SKU and category levels; implement corrective actions and model enhancements to continuously improve forecast performance.
  • Build and execute replenishment rules, safety stock algorithms, and order templates within planning systems to automate routine ordering while ensuring governance and exception management.
  • Lead daily/weekly exception management reviews: prioritize critical stockouts, overstock risks, and inbound discrepancies; coordinate corrective actions with operations and suppliers.
  • Analyze and model price elasticity, markdown cadence, and promotional ROI to inform pricing recommendations and markdown timing that minimize margin erosion.
  • Provide detailed inventory and sales analyses to senior merchandising and finance partners to support assortment decisions, inventory investments, and promotional funding requests.
  • Maintain master data hygiene for SKUs (lead times, pack sizes, case pack, UPC, category attributes) and work with data governance teams to correct or enhance item attributes that drive planning accuracy.
  • Coordinate seasonal buy planning and financial plan reconciliation, ensuring that planned receipts and inventory align with merchandising financial targets and P&L expectations.
  • Drive cross-functional release and allocation of limited inventory for high-demand launches or constrained supply situations with fair and strategic distribution methodologies.
  • Implement continuous process improvements and automation opportunities (macros, macros-to-MRP, macros-to-BI) to reduce manual work and accelerate decision cycles.
  • Execute root cause analysis for supply chain disruptions (delays, quality issues, purchase order changes) and lead mitigation plans to minimize lost sales and excess inventory.
  • Partner with E-commerce and omnichannel teams to optimize inventory visibility and fulfillment rules for click-and-collect, ship-from-store, and ship-to-customer strategies.
  • Prepare and present weekly and monthly planning reviews, inventory health dashboards, and KPI scorecards for merchandising leaders and operations stakeholders.
  • Drive compliance with company inventory policies, purchase order change protocols, and vendor lead-time agreements to protect supply reliability and financial controls.
  • Manage ad-hoc analysis for product line extensions, test-and-learn assortment pilots, and geographic rollouts to quantify inventory impact and expected ROI.
  • Oversee returns and reverse logistics considerations for planned inventory, including refurbishment, resale, and disposition strategies that recover margin.
  • Mentor and train junior planners and cross-functional partners on planning tools, forecasting methodologies, and exception management best practices.
  • Participate in systems selection and upgrade projects (APS, OMS, ERP, Forecasting tools) providing category-specific requirements and UAT testing to ensure planning workflows are supported.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis.
  • Contribute to the organization's data strategy and roadmap.
