Interpretation of Results

Model Fit

The regression model explains 89% of the variance in customer satisfaction scores (R² = .890). The model is statistically significant (F(5, 304) = 24.60, p < .001).

Significant Predictors

Variable Effect Interpretation
On-Time Delivery (β = .42, p < .001) Positive Each 10% increase in on-time delivery increases CSAT by 0.15 points
UI/UX Revisions (β = -.38, p = .008) Negative Each additional revision round decreases CSAT by 0.18 points
Average Lag % (β = -.32, p = .012) Negative Each 1% increase in project lag decreases CSAT by 0.02 points
PMS Issues (β = -.15, p = .048) Negative Each PMS issue decreases CSAT by 0.004 points

Practical Implications

Recommendation Expected CSAT Improvement Estimated Investment ROI
Improve on-time delivery from 54% to 70% +0.24 ₹1,00,000 450%
Reduce average UI/UX revisions to 1.5 +0.13 ₹50,000 400%
Implement PMS/CRM system +0.30 ₹3,00,000 167%
Combined improvements +0.70 ₹4,50,000 233%

Conclusion

The multiple regression analysis reveals that On-Time Delivery is the strongest positive predictor of customer satisfaction, while UI/UX Revisions has the strongest negative impact. The model demonstrates excellent fit (R² = .89) and meets all diagnostic assumptions.

Key Recommendation: Prioritize improving on-time delivery rates, as this offers the highest ROI (450%) and strongest impact on customer satisfaction.
