When you consider the expected benefits of a solution, you focus on the positive value that a particular design option can bring to the business when it is delivered. The expected benefits can include financial benefits as well as benefits such as reduced risk, compliance with business policies and regulations, improved user experience, or any positive outcome for the organization.

A real-world example could be described as follows:

The stakeholders of an organization agree that a new website is required to represent the organization online and they would like an external website provider to manage and implement this solution. 

It is expected that the new website will run on a faster hosting platform, which could improve traffic to the website and, therefore, also increase product sales.

It is expected that a new website will provide the company with a new market image that will make them more attractive to potential new clients. It is also expected that the user experience will be much better than using the current website.

In this example, there are two key expected benefits identified with a particular design option. These benefits relate to an increase in sales (financial benefit) and an improved reputation and brand image, which will attract more customers and satisfy existing customers from a user-experience perspective.
