Requirements

• A live Open Banking feed already connected, with its own re-authentication tracker already running — covered in the Open Banking Capsule elsewhere in this catalogue
• A list of every third-party tool you believe has access to your bank data, even an incomplete first guess
• Excel or Google Sheets. No other software, and no legal or compliance background
• About 15 minutes for the diagnostic, 20 minutes for your first full baseline, then a quarterly review of roughly the same length
• Work in this order: complete the Readiness Diagnostic first, being honest about what you don't currently know.
• Watch Segments 1 and 2 before building the baseline. Understanding what this Capsule actually requires, and the four ways it quietly fails, changes what you'll look for.
• Extend your existing Open Banking re-authentication tracker with the two new compliance columns from Segment 3, rather than building a second tracker.
• Run your first full baseline as taught in Segment 4, and log it — even a partial or gap-revealing result — as your first audit-trail entry.
• Set a quarterly reminder and re-run the full checklist every time, logging the outcome whether or not anything needs fixing.
