Features of BowTie Pro

Some of the key features that make BowTie Pro the fast and easy to use risk analysis tool

When analysing the controls, it is easy to record detailed categorisations and information such as tasks, task assignment to people, documents with hyperlinks, verification methods and deficiencies. The deficiencies can be built up in various places in a diagram and an action plan can be generated.

BowTie Pro™ can produce a Risk Register listing all the Risk Matrix results allowing easy identification of the high risk tasks.

BowTie Pro™ is a very feature rich program which can go far beyond the bowtie and lead into Human Factors, Equipment Analysis, Layers of Protection (LOPA) etc all for the same cost.
