# Pricing Model Lab

Pricing Model Lab is a synthetic Python project that compares observed values against model-derived values and flags material deviations for review.

It demonstrates a simple, structured decision-support workflow designed to turn raw inputs into consistent, reviewable outputs.

## Workflow

- Load structured data
- Validate required inputs
- Calculate deviations between observed and model values
- Apply threshold-based review logic
- Output a clean, ranked result

## Example Output

| item_id | observed_value | model_value | deviation | review_flag |
|--------|----------------|-------------|-----------|-------------|
| A-104  | 102.50         | 98.20       | 4.38%     | Review      |
| A-219  | 75.00          | 74.10       | 1.21%     | OK          |

## What This Demonstrates

- Python data pipelines
- Data validation and input control
- Comparative / pricing analysis
- Decision-support workflow design
- Reproducible, structured outputs
