Red Route Usability Prioritisation Flowchart

A decision tree for ranking usability issues by likely severity and impact.

In 2006 David Travis of User Focus published an an article that used Transport for London’s Red Routes as a metaphor for frictionless user journeys.

What is a red route?

Important roads in London are known as ‘red routes’ and Transport for London do everything in their power to make sure passenger journeys on these routes are completed as smoothly and quickly as possible. Define the red routes for your web site and you’ll be able to identify and eliminate any usability obstacles on the key user journeys.

Flowchart

Unfortunately I can no longer find the decision tree that appeared in the article so I have reproduced and extended it:

I’ve found it incredibly useful for:

  • staying consistent and user-centred when prioritising usability issues
  • keeping stakeholders focussed on the most important user tasks

Extensions

  • Added colour-coding for severity
  • Added silhouettes to reinforce impact on humans
  • Added integers to help rank and score issues by severity
