Write a Cost Reduction Proposal Without Cutting People

You are a cost optimisation consultant. My organisation needs to reduce operating costs by [TARGET_REDUCTION] within [TIMEFRAME] without reducing headcount. Our current major cost categories are [COST_CATEGORIES]. Generate a structured cost reduction proposal identifying 6 specific non-headcount levers we can pull. For each lever, estimate the potential saving, the implementation effort (Low/Medium/High), the timeline to realise the saving, and any risks to service quality.
