Compare · evidence reviewed 16 July 2026

Different tools, different strengths.

This comparison uses current vendor pages, not memory or sales shorthand. It describes product positioning; it is not a certification or legal opinion.

Short answer: Safran Risk already provides automated schedule validation and integrated cost-and-schedule risk. @RISK is a mature Windows Excel add-in for Monte Carlo analysis. Acumen Fuse provides broad schedule diagnostics and forensic comparison. Risk Studio brings four explicitly named assessment frameworks, source trace and a governed review workflow together, with internal quantitative results produced as cross-check evidence.

What Risk Studio adds: analyst-run tools assemble the evidence by hand; Risk Studio captures every run on an HMAC-chained audit log, byte-identically replayable, with every figure traced to its source row and a recorded per-finding accept decision. Your approved engine of record stays the system of record — this is independent, governed cross-check evidence, not a replacement.

01 · Safran Risk

Safran already covers validation and integrated risk.

Official source checked 16 July 2026: Safran Risk product page.

Area	Safran's official position	SOMA's current position
Schedule validation	Safran says Schedule Check automatically monitors and validates schedules.	Risk Studio runs 75 checks across SOMA QSRA Readiness, DCMA, CIOB PP21 and an Acumen-aligned metric set, with source trace.
Cost and schedule risk	Safran describes integrated cost and schedule risk analysis on one platform.	QSRA and Schedule Lens available; QCRA in supervised evaluation; QSCRA not offered.
Interoperability	Safran lists Oracle P6 XER, Microsoft Project XML and MPXJ interoperability.	Risk Studio supports verified schedule and risk-register workflows, and works alongside the approved engine of record.
Best fit today	A mature external engine for relied-upon quantitative analysis, including integrated cost and schedule.	Teams who want traceable validation and independent cross-check evidence alongside the approved engine.

02 · Lumivero @RISK

@RISK is Excel-native and mature.

Official source checked 16 July 2026: Lumivero @RISK product page.

Area	@RISK's official position	SOMA's current position
Working environment	A Windows-based Microsoft Excel add-in designed to keep analysts in the spreadsheet.	A web application with governed data structures and audit metadata; not a drop-in Excel replacement.
Modelling breadth	Monte Carlo simulation with more than 90 built-in distribution functions and cost/schedule use cases.	Six supported distribution types. QCRA is in supervised evaluation and does not replace @RISK.
Best fit today	Teams needing mature Excel-native quantitative modelling on Windows.	Teams evaluating a controlled, traceable assurance workflow alongside their approved tools.

03 · Deltek Acumen Fuse

Acumen Fuse provides broad schedule diagnostics.

Official source checked 16 July 2026: Deltek Acumen Fuse product page.

Area	Deltek's official position	SOMA's current position
Diagnostics	Deltek describes more than 600 industry-aligned metrics, automated forensic comparisons and configurable scoring.	Risk Studio exposes 75 checks across four named framework views with source trace.
Ecosystem	Fuse integrates with Deltek Open Plan, Oracle Primavera P6, Safran Project, Microsoft Project, Phoenix and Powerproject.	Risk Studio is tool-neutral in selected import/export workflows but does not claim equivalent ecosystem depth.
Named deliverable	Use Acumen where a contract requires the official Acumen/Fuse product or branded output.	SOMA's Acumen-aligned checks are an internal framework view, not an official Acumen certification or branded report.

When Risk Studio is not the right choice.

When the contract names a specific approved tool or branded deliverable.
When combined cost-and-schedule analysis is required now: QSCRA is not offered.
When independent reliance on SOMA's internal quantitative result is required: that is outside the current availability boundary.
When the organisation cannot support the agreed identity, client-controlled storage and assurance controls.

Vendor pages change. This comparison must be rechecked against primary sources before any material commercial use.
