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

These documents serve different purposes: The issue log tracks the status and resolution of current problems. The lessons learned register captures knowledge — insights, recommendations, and best practices — that can improve future projects. Both should be updated, but with different information.

**Why not A:** This reverses the purposes. The issue log does not document lessons — it tracks the status and resolution of active problems. The lessons learned register does not track status — it captures knowledge and insights for organizational improvement.

**Why not B:** These are not redundant documents. The issue log and lessons learned register serve distinct purposes and both should be updated. The issue log records the resolution of the specific problem, while the lessons learned register captures the broader insight gained from the experience for future benefit.

**Why not D:** The issue log should be updated for all resolved issues, not only escalated ones. Every issue's resolution should be documented regardless of whether it was escalated. Similarly, the lessons learned register captures insights from significant experiences, not necessarily all issues.
