This answer states that canceling the workshop and rescheduling it to a date when all stakeholders are available is what the BA should do after receiving the calendar responses for an initial live process mapping session with all stakeholders for revamping its support process to improve the customer experience. A process mapping session is a collaborative activity where the BA and the stakeholders work together to document and analyze the current state of a business process, identify pain points and opportunities, and design the future state of the process. Canceling the workshop and rescheduling it can help the BA to ensure that all stakeholders are present and engaged in the session, and that their input and feedback are captured and considered.
