Raadix helps you to investigate, document and analyze incidents using Root Cause Analysis, PRISMA or comparable methods.

Raadix runs in a modern webbrowser (Chrome, Edge, Firefox, Opera, Safari) on your smartphone or iPad. However, a large screen of a desktop or laptop is more practical for large trees or timelines.


Define the incident. Store your notes, photo's, video's or documents. Create a timeline. Use the causes from the timeline to create a cause tree or fact tree. Set measures with followup dates. Import your Raadix for Windows files. Export your data to Excel. Save timeline and cause tree as an image (PNG).

Work together online. Multiple people can work on the same timeline and view activities of other users in real time.

Personal group

Each user has a personal group, where all private incidents are located. No one has access to the personal group of another user.

Common group

In a common group member of the group can share their incidents. You can work together (e.g. by video call). All users viewing a time line or cause tree in a common group can directly see what others are adding or modifying. Only group members have access (e.g. department or organisation).


Raadix.com is build on Google Cloud Services. This tried and tested cloud infrastructure offers state of the art security for the data and the datacenters. All data is encrypted and stored inside the EU (currently in the western part of Germany).


Raadix.com uses the minimum amount of your personal information to safely give you access (e.g. e-mail address). NO other personal data like your browser history or your location is stored. NONE of your data is shared with third parties. All your data remains your own property and/or the property of your organisation.
