Capturing lessons learned in SAP OCM (typically Run phase) improves future projects, and the process design is key. Option B is correct because a predefined structure (e.g., categories like planning, execution, adoption) and scope (e.g., OCM-specific issues) ensure all aspects—successes and failures—are covered systematically. Without this, discussions might miss critical insights, like overlooked stakeholder engagement flaws. Option E is correct as clear rules (e.g., “no blame”) create a safe environment, encouraging honest input—e.g., a team member might hesitate to admit a communication delay if fearing criticism, stunting learning.

Option A is incorrect—confidentiality may limit sharing valuable lessons with the organization, contradicting SAP’s goal of building capability; transparency (with discretion) is preferred. Option C is incorrect; focusing only on negatives ignores successes (e.g., effective training), skewing the process and wasting potential insights, not saving time. Option D is incorrect—a workshop isn’t always best; surveys or interviews might suit smaller teams or remote setups. SAP OCM advocates flexibility and constructive design.

“Design lessons learned with a structured scope and clear rules like ‘avoid finger-pointing’ to ensure comprehensive and open feedback” (SAP Activate, Lessons Learned Process).
