Explanation

Information Management Model (IMM) is purpose-built for exactly this task - it provides a structured framework to decompose user roles, processes, and data relationships into increasingly granular levels until ambiguity is eliminated, making it the go-to tool for ISSEs organizing complex information environments.

Why the distractors are wrong:

• A. PERT Chart - a project scheduling tool that maps task dependencies and timelines, not roles or information structure
• B. Gantt Chart - another project management tool showing task duration over time, unrelated to role/information decomposition
• C. Functional Flow Block Diagram (FFBD) - shows the sequence of system functions, but doesn't drill down into user roles and information to resolve ambiguity

Memory tip: Think of IMM as "Information Mapping = Meaning" - its whole purpose is to map out information until everything has a clear, unambiguous meaning. If the question mentions reducing ambiguity around roles, processes, or information, that's the IMM's signature job description.
