Our take
Where o9 Solutions leads
- Stronger evidenced coverage on 13 of the 28 capabilities where they differ (led by digital supply chain twin / simulation and supply chain control-tower visibility).
Where RELEX Solutions leads
- Stronger evidenced coverage on 15 of the 28 capabilities where they differ (led by assortment planning and price optimization).
Where they differ
The 28 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.
