Introduction

For those customers that want the possibility to create quantitative and semi-quantitative analyses, built on the bow-tie model, Governors has developed BowTieXL.

Features

BowTieXL introduces a Microsoft Excel compatible spreadsheet into BowTieXP, which exposes all the information in the case file as tabular data in this spreadsheet. This allows you to use that data to do spreadsheet calculations, based on that data, and feed the results back into your bow-tie model.

It also allows you to define extra variables on the bow-tie diagram itself for use in calculations. This functionality gives you a lot of freedom to create what you need. You can for instance calculate average effectiveness of controls, use the effectiveness score to colour controls, create a financial model that lets you know what the cost reduction is for each control that you add or make a questionnaire that feeds back into your bowtie.

Applications

BowTieXL was designed without any single model in mind. Instead it was designed to encompass all possible models. This means that it can be used to display for instance LOPA, or any other model that you want to superimpose on the Bowtie.

Apart from being able to do calculations based on the bow-tie model data, you can also use BowTieXL to:

• Store reference information in spreadsheets, which are stored in the case file
• Add notes and calculations which serve as underpinning of the analysis in the case file
• Add general reference information into the case file
• Use the tabular representation of the bow-tie model data to quickly edit data in bulk
