# ROS/RMS Analysis
## Metadata
- **Name**: ros-rms-analysis
- **Description**: Return on Sales vs Relative Market Share analysis
- **Triggers**: ROS, RMS, economies of scale, competitive advantage, profitability
## Instructions
Analyze relationship between Return on Sales (ROS) and Relative Market Share (RMS) to identify competitive advantage from scale.
## Framework
### The ROS/RMS Equation
```
ROS = Operating Profit / Revenue
RMS = Our Market Share / Largest Competitor Market Share
```
### Key Insight
**If ROS > Industry Average AND RMS > 1 →**
Both superior profitability AND scale advantage = strong competitive position
**Economies of Scale Logic:**
- Larger RMS → Should have lower costs → Higher ROS
- Smaller RMS → Acceptable to have higher costs → Lower ROS
### Chart Types
**Scatter Plot** - ROS on Y-axis, RMS on X-axis (log scale)
**Trend Line** - Industry average ROS vs RMS
**Sector Chart** - Multiple competitors positioned in quadrants
## Output Process
1. **Define industry** - Boundaries, products, geography
2. **Gather data** - Revenue, profits, market shares
3. **Calculate metrics** - ROS for all players, RMS for us
4. **Benchmark** - Industry average ROS, competitive thresholds
5. **Create visualization** - Scatter or sector chart
6. **Interpret results** - Identify positioning and scale effects
## Output Format

## ROS/RMS Analysis: [Industry/Company]
### Company Positioning
| Competitor | Revenue | Profit | ROS | RMS | Position | Scale | Position |
|------------|---------|--------|------|----------|---------|
| [Company A] | $X M | $Y M | Z% | 0.5 | Small | ❌ Cost disadvantage |
| [Company B] | $X M | $Y M | Z% | 1.2 | Medium | ❌ Cost disadvantage |
| [Company C] | $X M | $Y M | Z% | 0.8 | Large | ⚠️ Mixed |
| [Company D] | $X M | $Y M | Z% | 2.5 | Leader | ✅ Scale advantage |
### Trend Analysis
| Metric | Our Value | Industry Avg | Assessment |
|--------|-----------|-------------|------------|
| ROS | X% | Y% | 🟢 Below average |
| Market Share | Z% | - | 🟡 Losing share |
| Growth Rate | X% | Y% | 🟢 Below market |

### Economies of Scale Analysis
**Regression Line:** ROS = a × (1/RMS) + b
- If 'a' is significant and positive → Strong economies of scale
- If 'a' is insignificant → Weak or no scale economies

## Tips
- Use multi-year averages for ROS (3-5 years)
- RMS on log scale (1.0 = equal to leader, 0.5 = half)
- Industry ROS varies by sector - don't assume universality
- Look for outliers - they tell important stories
- Consider market share trends - gaining share can compensate for lower ROS
