Bowtie Perspectives

There are many uses for a bowtie and with each use comes the requirement for a consistent visual format that highlights the important.

Bowtie Perspectives let you capture and apply all aspects of the presentation format to any number of bowties, delivering a fast method to simplifying and standardise another aspect of company risk communications.

Have a look at this video to get an overview of how bowtie perspectives work:


Applying Bowtie Perspectives

Bowtie Perspectives are available via the drop-down menu on the toolbar when editing a bowtie:

Bowtie Perspectives Menu

Clicking on any selection will format the current bowtie according to the settings saved in the Perspective.

All Perspectives created by Administrators are available to all other Users. The locks above on the left hand side of each Perspective show that the Administrator has locked some perspectives but not others. Once locked, they can only be edited by the Administrator. Any user with access to view bowties also has the ability to create and manage their own Perspectives.

Defining a Perspective

You can create a Perspective by clicking on the New Perspective link at the bottom of the drop-down list. The following dialog will be displayed:

Start Page

The Start Page allows you to set the context for the Perspective, by selecting the Analysis Type it is to be used for and if will be showing Current and/or Proposed Risk values. These can be changed at any time during the Perspective building to see how the perspective will handle those different values, as they are set and maintained within each Bowtie.

General Page

The General Page allows you to set the Name and the overall look and feel of the bowtie:

The functionality specified on a field by field basis is:

  • Name: a unique name to aid in recalling it later.
  • Automatically apply layout: so that the layout algorithm is applied every time a new node or edge (the link between nodes on a bowtie) is created or deleted, without the user having to press the Layout button manually.
  • Allow pathway wrapping and Length: wraps long lines of controls so that the bowtie is easier to read and at higher resolutions. No wrapping looks like this:

  • Edge Widths, Min, Max and Likelihood Source for Edge Width: delivers variable thickness edges on the bowtie based on the selected likelihood source for edge width.
  • Title Options and Show entire node title: cuts the node title to a defined number of lines or allows them to flow without limit.
  • Node Selection Border Options, Width and Colour: allows you to specify the colour and thickness of the selected item highlight.
  • View Style: Let’s you choose between the classic style and the tabular style bowties. Classic style is as per above. Tabular style is as follows:

Once the general properties are setup, we can move to each of the node types, starting at the Top Event.

Top Event

Clicking the Top Event tab, displays this page:

As for all node types, the Colour Source lets you specify from which property located on the node should the Perspective get the colour of the node. Original means the default property a number of others can be selected as seen here. Note that every node will only show those properties that exist within that node. And of course, when the property changes so will the colour of the node.

On the right hand side is the Preview of the node, in this case, the Top Event:

All of the fields can be moved up and down, removed, swapped with items from the Available Fields list, and field headers and prefixes can also be included.

The fields shown in the Available Fields list will vary according to the selections in the Risk Analysis Type, Show Current Risk and Show Proposed Risk fields, as will the contents of the Preview. This is because from within each Bowtie’s properties, these settings can be individually altered.

Those fields shown with an (i) to the right are conditionally visible based on whatever criteria, as seen below:

This also helps with identifying fields that might otherwise have the same name.
