This is where the customer onboarding process becomes such a crucial component of the overall customer experience. Of course, you can't create a comprehensive onboarding program without the help of other parties such as technical support, product specialists, and customer service. However, you can provide a seamless experience for the client by coordinating communication and acting as the point person during the onboarding process. You can also solicit feedback from the client and ask for their help in drafting an onboarding plan. Since the end users of your product are likely to be a diverse group of individuals, it is important to work with the technical team to develop a training program that is accessible for users with many different learning styles.
