Pick n Pay, one of Africa's largest retailers, implemented SAP across its operations to standardize its fragmented systems and take advantage of SAP's alignment with its business processes. The multi-year implementation involved rolling out SAP financials, retail, warehouse management and other solutions to different regions over time. Key challenges included losing internal focus during implementation and lack of IT skills. Critical success factors were teamwork across the ERP project, top management support, minimizing customization, and appointing project champions. Lessons learned highlighted the importance of buy-in, managing costs and skills, change management, and security during a large ERP rollout.
