#### Video transcript

One of the defining capabilities of a customer data platform is its ability to create a single customer view. Customers interact with brands across many channels, websites, mobile apps, email campaigns, loyalty programs, advertising platforms, and offline transactions. Each of those interactions generates data, but that data is often stored in a completely separate system. Identity resolution is the process that connects those fragmented records together to form a unified customer profile. Without identity resolution, each interaction might appear to come from a different person. With identity resolution in place, those interactions are stitched together into a single, continuous customer journey. For example, a visitor might first browse your website anonymously, later they subscribe to an email newsletter, eventually they make a purchase tied to a loyalty account. Each of those interactions may generate separate identifiers. The goal of identity resolution is to link those identifiers together so the platform recognizes them as the same customer. In Lytx implementations, identity resolution relies on persistent identifiers such as email addresses, customer IDs, a device ID, or a loyalty account ID. These identifiers act as the anchor that allow the system to merge data from multiple sources into a unified profile. As the implementation progresses, the team defines rules that determine how these identifiers should be matched and prioritized. For example, email addresses may be treated as a primary identifier because they are stable and widely available across systems. Device IDs or cookies may be used to associate anonymous browsing activity with known users once they authenticate or submit a form. During this phase, testing becomes extremely important. Identity resolution errors can have serious downstream effects. If two individuals are mistakenly merged into a single profile, segmentation and personalization logic can produce inaccurate results. This is often referred to as over-merging. On the other hand, if identifiers fail to connect correctly, the same customer may appear as multiple profiles across different channels. This is known as under-merging and it limits your ability to understand the full customer journey. To prevent these issues, teams typically run validation tests that simulate how records should be merged across systems. Additional data may be injected into the platform to confirm that identifiers connect as expected and that the resulting profiles reflect real customer behavior. As the project manager, your role is to coordinate these validation efforts. You help schedule cross-functional reviews or identify rules, ensure that identifier strategies are documented, and confirm that testing results are reviewed by both technical and business stakeholders. When identity resolution is implemented correctly, the platform gains the ability to recognize customers consistently across devices, channels, and interactions. That unified customer view becomes the foundation for segmentation, personalization, and meaningful customer engagement across the organization.

#### Key takeaways

- Connect **Identity Resolution and the Single Customer View** back to your stack configuration before moving to the next module.
- Capture one concrete artifact (screenshot, Postman call, or code snippet) that proves the step works in your environment.
- Re-read the delivery versus management boundary for anything you changed in the entry model.
