Yes, and the external review has a dashboard. It ran for roughly 12 weeks. The most recent one started in the fall of 2023. It just wrapped up in March 2024. It shows the absolute number of tickets and the breakdowns between critical, high and medium. It will show that, as I sit here, 99% of the issues raised during the process have been resolved. I'm very happy to present that evidence.
I think the important point is that for the external testing, businesses were invited in to use real-world scenarios. I take confidence from the fact that we did identify dozens of issues and repaired them through the process.
I think it would be misleading for me to say we're going to release this system and there are going to be no issues. There are going to be issues. What we're trying to do is prove that we have the discipline and mechanisms to address the inevitable tickets, questions and concerns that come from any big IT project.
We had five critical problems during that four-month period. Our service standard to resolve a critical problem is 24 hours.
What makes me confident is that we road-tested the ability to find a critical problem, get the right people to talk about it and resolve it within 24 hours. When you're running a $40 billion-a-year revenue system, you're going to invariably encounter issues. I take comfort from the fact that we tested our ability to find and fix problems.
