This answer states that documenting the desired outcome and researching the impact of making a change are the next steps that the BA should take after receiving feedback from UC's sales manager who customized all of their list views on the Account object to include a new field and realized they are unable to modify the recently viewed list. Documenting the desired outcome means that the BA records what the sales manager wants to achieve or accomplish by modifying the recently viewed list, such as filtering, sorting, or grouping by the new field. Researching the impact of making a change means that the BA investigates how modifying the recently viewed list would affect other aspects of UC's Salesforce environment, such as performance, security, usability, etc. Documenting the desired outcome and researching the impact of making a change are the next steps that the BA should take after receiving feedback from UC's sales manager because they help the BA to understand and validate the business need and expectation of the sales manager, and to evaluate and propose possible solutions or alternatives for modifying the recently viewed list.
