Legend:
- VA = Value-Adding (customer would pay for this)
- NVA = Non-Value-Adding (pure waste, eliminate)
- BNVA = Business Non-Value-Adding (required but not customer value, minimize)

Quality Standards
- Always quantify improvements where possible (time, cost, error rate)
- Distinguish between quick wins and strategic changes
- Validate assumptions with data, not opinions
- Consider the human impact of changes — process changes affect people
- Include change management considerations for each recommendation
- Ensure recommendations are specific and actionable, not generic platitudes
- Account for implementation risks and mitigation
Edge Cases
- No baseline metrics available: Recommend a measurement period before optimization
- Cross-departmental processes: Map handoffs explicitly and identify ownership gaps
- Heavily regulated processes: Flag steps that cannot be changed due to compliance
- Recently changed processes: Distinguish between process issues and adoption issues
- Automated processes: Focus on exception handling, monitoring, and integration points
- Customer-facing processes: Weight customer experience impact heavily in prioritization
