Our take
Where GMDH Streamline leads
- Stronger evidenced coverage on 22 of the 29 capabilities where they differ (led by forecast accuracy & bias reporting and order-quantity / eoq optimization).
- Stated SAP integration the alternative doesn't list.
Where Inventory Planner by Sage leads
- Stronger evidenced coverage on 7 of the 29 capabilities where they differ (led by excess & obsolete inventory identification and causal & external-signal modeling).
Where they differ
The 29 capabilities (of 62 in the demand & supply planning taxonomy) where the evidence separates them, biggest gaps first. “Not evidenced” means our research found no public documentation of this capability — the vendor may still offer it. Confirm on a demo.
