This report analyzes production and profitability through the lenses of break-even thresholds, profit modeling, customer value segmentation, and statistical outlier detection. It blends daily and monthly operational performance with customer-centric insight.
Key Highlights: - #r round(mean(df$units_produced > 100) * 100, 1)`% of production days exceed break-even - Contribution margin provides clearer visibility than flat accounting cost models - RFM segmentation identifies top-tier customers and at-risk segments

Insight: Extreme losses are primarily under the accounting model and often tied to small transactions with high fixed cost load. The contribution model minimizes variance and outliers.

Insight: Champions and Loyal customers consistently deliver stronger contribution margins and volume. At-Risk segments show weaker economics and may warrant reactivation efforts.
This report has surfaced key operational and customer-level patterns. Here are the most actionable takeaways:
Adopt Contribution Margin Modeling
Traditional accounting profit penalizes small orders due to unscaled
fixed costs. Contribution margin offers fairer unit economics and more
stable analysis.
Re-engage or Retire Low-RFM Customers
βAt-Riskβ and low-score segments produce low volume and margin.
Reengagement campaigns or segmentation-based pruning may enhance
ROI.
Optimize Delivery Modes
Certain delivery modes consistently underperform in margin. Target cost
reduction or pricing tweaks by delivery tier.
Monitor & Refine Cost Model Noise
Outlier losses suggest room for refining pricing structure, assumptions,
or noise introduced in total costs. Flag transactions for review if
outside IQR.
Consider Scaling this Model into Power BI
This same structure can be converted into a refreshable dashboard with
live segmenting, break-even logic, and margin overlays per
dimension.
