Spreadsheet feature overview

  • What is Spreadsheet feature?

    What is Spreadsheet feature?

    The Spreadsheet feature in BowTieXP Complete allows you to create your own methods for quantified and visual risk assessment in BowTieXP.


    The application 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 bowtie 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 color 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.
