Beau-Tie

Map any risk as a clear bow tie diagram - causes, impacts, and the controls between them. Build from 10 templates, rate on a 5×5 matrix, export as PDF or image.

Beau-Tie turns risk analysis into clear, shareable bow tie diagrams — built for your iPhone and iPad by Monty & Co.

A bow tie puts your risk event at the centre, its causes on the left, its impacts on the right, and the controls that stand between them on the lines where they act. One picture that shows what could go wrong, why, and what you're doing about it.
