The product development team at Northern Trail Outfitters is creating a process within Salesforce to onboard new retail employees. The business analyst (BA) creates a current state process map by interviewing a few members of the onboarding team using email questionnaires. After presenting the process map to the entire onboarding team, the BA receives feedback that it is incorrect.

What should the BA do to provide the product development team with more accurate information about the onboarding team's process?
