RelQuest: Fault Tree Modelling for Commercial Development
The Challenge
Enable simple qualitative and quantitative modelling of complex system failure probabilities with a simple toolset based on Visio.
Description
RelQuest is a tool to support Fault Tree Analysis of hardware and software system reliability. It is based on a simplified modelling approach, which allows analytical (and therefore almost instantaneous) evaluation of the model. It supports base events, AND, OR and VOTE gates.
RelQuest is implemented as a Visio™ Add-In.
I originally developed it as a personal tool to support a reliability study I was performing for an early version of the Sky digital platform. After that I was able to adapt the idea for further commercial development.

Outcomes
Viable solution which helped resolve the problem for my client at the time, and which I was then able to offer as a commercial product.
Timescale
1998
Current Status
Would need rework to latest tool versions, but still available on request
