CAPM Practice: Demonstrate an understanding of common problem-solving tools and techniques

The failure to identify a key risk because each group assumed the other was monitoring it is an organizational assumption failure — a classic case of the 'diffusion of responsibility' or 'assumption gap.' The lesson learned should recommend improving risk identification processes to explicitly assign ownership and avoid assumption-based gaps in coverage.

**Why not A:** While clearer role definitions could help, the root issue is not about resource management. The problem is that each group assumed the other was monitoring the risk — this is an assumption failure in risk identification processes, not a staffing or role assignment issue.

**Why not B:** While communication may have contributed, the core problem is not about communication plans or reporting. The fundamental failure was in the risk identification process where assumptions about ownership went unvalidated, creating a gap that no communication update would have addressed.

**Why not D:** Scope creep involves uncontrolled expansion of project scope. The scenario describes a missed risk due to assumption gaps, not unauthorized additions to the project scope. Change control would not have prevented this type of organizational assumption failure.
