BCS Exam RE18 Topic 11 Question 32 Discussion

Isamu is a business analyst working on a project. Unfortunately, it is not progressing as hoped or planned.

He has identified that the main issues with the users on the project are:

1) They manage complex processes and they do not seem to be able to articulate their needs.

2) They claim they cannot engage in requirements elicitation as they simply do not know what is possible.

Which elicitation technique would best address both these issues?
