When GDPR was announced most companies didn't notice. Some companies did. Working at CRMT meant we had a lot of customers dealing with a lot of customer data and GDPR meant that the current methods most companies were using to collect and store, and allow customers to view and change what was being stored was no longer viable.
What arose from this was the need for a single place where the marketing information for individuals could be stored, and accessed, along with allowing them to opt-in and out and remove any preferences they had set. Thus we built the preference centers.
Wireframe for internal use
Initially a wireframe was constructed which we could use as a basis for all other examples to keep it simple and templated
The wireframe proved successfull so this was then used for a client test
Real Life Testing
Finally this was deployed for use on a real life use case.
