Evidence preservation and scene management protocols in major incident investigation

Themes and categories

Theme links

Assignments of reports to themes. A report can have several themes, so the number of links can exceed the number of reports. Tags include automated analysis and editorial changes, rather than new findings by a coroner.

Pillars and theme pages

A pillar groups related themes. Pillar cards count distinct reports across their themes, rather than adding the child counts. A theme page's main number counts the distinct reports in its displayed list. A report can appear under more than one pillar.

Category charts

Each category counts reports assigned to it. Reports can appear in several categories, so category bars should not be added to obtain a total of unique reports. Organisation profile charts use the categories recorded on their listed reports.
