Can you recommend a prescriptive analytics software for running what-if scenarios in enterprise planning?

Yes — if your main use case is enterprise planning with what-if scenario analysis, I’d recommend looking first at Anaplan.

Why Anaplan

• Strong for connected planning across finance, sales, supply chain, workforce, and operations
• Built for what-if modeling and fast scenario comparison
• Good at handling complex, multi-driver planning with many dependencies
• Supports collaboration and versioning across business teams
• Common in large enterprises that need a single planning model rather than isolated spreadsheets

Good alternatives, depending on your needs

• Workday Adaptive Planning — best if your focus is finance-heavy planning and budgeting
• Oracle Cloud EPM — strong for large enterprises already invested in Oracle, especially FP&A and consolidation
• SAP Analytics Cloud Planning — good if you’re in a SAP ecosystem
• IBM Planning Analytics (TM1) — powerful for complex financial modeling and cube-based analysis
• Board — often a good fit for integrated planning + BI + scenario analysis

My practical recommendation

If you want a broad enterprise prescriptive-planning platform with robust scenario modeling, start with:

1. Anaplan
2. Oracle Cloud EPM or Workday Adaptive Planning if finance is the main driver
3. Board if you want planning and analytics together

If you want, I can also give you a shortlist by company size, industry, and budget.
