Understand the journey for the multiple personas involved in the process. You need to understand the journey for each persona that participates in or interacts with the customer onboarding process, such as the customer, the client specialist, or the manager. You can use tools such as personas, journey maps, or user stories to capture the needs, goals, pain points, and expectations of each persona and how they experience the process from their perspective.

You need to determine the best e-signature solution to use for collecting and processing digital signatures from customers during the onboarding process.
