ERP systems include planning modules (SAP IBP, Microsoft Dynamics, Oracle NetSuite, and others), and they're convenient. But convenience doesn't mean capability.

Common shortfalls: Slow data refresh cycles limit real-time visibility, hard-coded logic restricts flexibility, scenario planning often requires separate tools, and workflows are built for finance-not supply chain users.

McKinsey research shows that ERP-native planning modules struggle with today's volatility, especially in multi-tier or global networks. ERP excels at execution, but planning is a different challenge. When you need to model trade-offs, mitigate risk, or react quickly, it becomes a bottleneck.
