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?

Entirely in the EU (Hetzner, Nuremberg, Germany). No application data leaves the European Union. Analytics is self-hosted and cookie-free. A data processing agreement per Art. 28 GDPR is in place with the hosting provider.
