The full picture, in one view.

A bowtie diagram shows the full picture in one view — every cause on one side, every consequence on the other, and every barrier in between. Anyone from the frontline to the boardroom can see at a glance how a risk is being managed, and whether it's under control.

BowTie Risk was developed by professional risk consultants, as barrier risk management software built on decades of barrier-based risk assessment practice — used in aviation, healthcare, energy and government.

Every design decision — from the cognitive science behind the layout to the offline-first architecture — reflects real-world risk assessment and compliance needs, not a feature checklist.

Built on cognitive science

Miller's Law

In 1956, psychologist George Miller demonstrated that the human brain can only hold 7 (±2) items in working memory at once. Overload that limit and decision-making breaks down.

BowTie Risk is designed around this principle. The bowtie structure deliberately organises complex risk information into focused, bounded groups — threats on one side, consequences on the other — so your brain can process each element clearly without becoming overwhelmed.

Chunked information

Threats, controls and consequences are each grouped separately, keeping each chunk within cognitive limits.

Visual clarity over data overload

A single bowtie replaces pages of text — letting you see the full risk picture at a glance, not wade through it.

Better decisions under pressure

When risks are structured to match how the brain works, teams respond faster and more accurately in critical situations.

Native Architecture

Built for Professional Risk Assessment. Native, on your own hardware.

BowTie Risk was built from the ground up as native Apple software: the same professional bowtie methodology, running entirely on your own Mac, iPad or iPhone. No virtualization, no browser, no compromise.

Legacy Bowtie Software BowTie Risk
Platform Windows-only, no native mobile app Native on Mac, iPad and iPhone
Works without signal Cloud versions need an internet connection Yes — full functionality offline, on-site

This isn't necessarily an either/or — plenty of risk teams keep a heavyweight system of record for enterprise reporting and use BowTie Risk alongside it, as the fast way to actually build and share a diagram with the people who need to understand the risk. See the full comparison →
