Typical Implementation Phases

Strategy and scope: Define service objectives, network scope, target operating model, and business case.
Current-state assessment: Document processes, systems, data quality, pain points, controls, and integration dependencies.
Future-state design: Establish planning policies, inventory parameters, fulfillment rules, warehouse processes, roles, and KPIs.
Vendor selection: Issue requirements, evaluate demonstrations, validate references, and assess total cost of ownership.
Data foundation: Cleanse and govern item, supplier, location, bill-of-material, inventory, lead-time, and transportation master data.
Integration design: Connect ERP, procurement, suppliers, carriers, WMS, TMS, marketplaces, finance, and analytics.
Configuration and extensions: Configure standard workflows first; limit customizations to justified differentiators.
Pilot and testing: Perform unit, integration, volume, security, user-acceptance, and operational simulations.
Deployment: Use phased, regional, process-wave, or controlled big-bang rollout as appropriate.
Change management: Train users, suppliers, warehouse staff, planners, and managers; establish governance and support.
Stabilization and optimization: Tune forecasts, safety stocks, workflows, labor standards, carrier rules, and exception thresholds.
