Comparison

DecisionOS vs Excel and slide decks

Spreadsheets and slide decks are a fine starting point for small decisions. They break down the moment multiple stakeholders, compliance scopes and weighted criteria enter the picture. DecisionOS replaces the spreadsheet-plus-deck pattern with one structured workflow that keeps criteria, evidence, stakeholders and risks in a single auditable artefact.

TL;DR

Spreadsheets work until the second stakeholder shows up.

Choose DecisionOS when

  • ✓More than three stakeholders touch the decision.
  • ✓The decision is auditable under NIS2, DORA, ISO 27001 or SOC 2.
  • ✓You expect to defend the decision 12+ months later.
  • ✓The decision is part of a recurring pattern (EDR, IAM, cloud, ERP).

Stick with Excel when

  • ·Informal decisions between two options with no compliance scope.
  • ·Personal or team-internal tooling with no external exposure.
  • ·One-off trade-off analysis with no re-use value.

How DecisionOS is different

A spreadsheet is a grid. A slide deck is a narrative. A decision memo is an object of record. DecisionOS treats the decision itself as the primary object, with criteria, evidence, stakeholders and risks as its structured attributes. That allows per-role briefs, readiness scoring and audit export to be derived automatically instead of manually re-produced per audience.

Questions we get about this

Can I import my existing spreadsheet into DecisionOS?

Vendor lists, criteria and cost data can be imported during onboarding. DecisionOS does not force a rewrite of your prior work; it structures it.

What happens to the Excel files once we adopt DecisionOS?

Most teams keep Excel for ad-hoc one-off analysis and move recurring decision patterns into DecisionOS. Export to PDF is always available for stakeholders who expect a document.

Where is DecisionOS hosted?

The application, its databases, the self-hosted analytics and all backups run on dedicated servers in Germany operated by a European provider, under an Art. 28 GDPR data processing agreement. There is no hyperscaler, no US fallback and no cross-border replication of stored data. Two steps do leave the EU: decision memos and document extraction are generated by an AI provider in the USA and carry case content, and traffic reaches you through a content delivery provider that terminates TLS in front of the origin. Vendor research runs on anonymized prompts and carries no customer identity. These transfers rest on EU standard contractual clauses, and every sub-processor is listed by name, purpose and location at nexalign.io/hosting. Whether a given workload can accept them is a question we would rather you decide with the facts than discover later. The self-hosted analytics is cookie-free.
