The heatmap is a graphical representation of data where individual values contained in a matrix are represented by colours. This is a useful visual tool for the Safety Manager to identify the trends for Safety Cases. Using the ‘Show filters’ button allows the display to be manipulated / interrogated depending on the filtering options chosen.
Start Date and End Dates – Here you can filter for specific dates. For example, you might only want to see Reports that have been submitted within the last 6 months.
Scoring for Closed Cases – Closed cases scored as zero or include closed cases in score
Multiple categories – Double count or split equally
Rows – The ability to filter through available options
Columns - The ability to filter through available options
Understanding the Heatmap
The heatmap displays based on the filtering options that have been selected. There is a total score displayed, this is the cumulative score of all cases that have been classified and have an ERC score.
The number in the circle shows how many cases have been reported in this subsystem in total.
Clicking on this score area and scrolling down the screen displays the cases and their different phases that they are in.
Depending on what is selected within the filter the heatmap displays the Safety Cases which match that selection.
Expanding a Row
If a Row has a downward pointing arrow next to its title (highlighted by the RED frame), then clicking on this arrow will expand the selection. When a selection is expanded if it shows a further arrow, it can be expanded again to view more granular detail.
Expanded row
Expanding a column
The same is true for the Columns. If there is an arrow pointing downward the selection will expand. If there is another arrow displayed you can filter further for granular information.
Expanded column
Column numbering - Within each cell there are two numbers. The first number is the total Score of all the Safety Cases ERC scored added together (Depending on what is selected within the Scoring Dropdown, this may include closed Cases).
The second number (within the circle) represents the number of Cases that are within this Cell including both Open and Closed Cases (Despite what is selected within the Scoring Dropdown).
Clicking on the column arrow expands the view for the selected filters in place providing granular detail.
Clicking on an individual cell will display the cases relating to it below the heatmap.
There is also a download feature on this page.
Colour Legend
Under the ‘Show filter’ button is an option to select Colour coding of the Heatmap.
The default is ‘Automatic’ which will colourise the heatmap on a gradient colourisation depending on its score.
There is a further option of ‘Standard’ which provide scoring based on three levels (individual cell, row total, grand total).
Total Score - The Total Score displays the Colour displayed for the entire Heatmap, this is then filtered further by selecting different column and row views to drill down to the detail of safety cases.
