Aprenda Evaluating Business Performance Through Metrics

Evaluating business performance requires a disciplined approach to tracking and analyzing a core set of metrics. These metrics provide a pulse on the health of your organization and allow you to spot trends, identify issues, and uncover opportunities for growth. Common business metrics include Daily Active Users (DAU), revenue, customer churn rate, and Net Promoter Score (NPS). By monitoring how these metrics evolve over time, you can make informed decisions and prioritize actions that have the greatest impact on your business objectives.

The first step in performance evaluation is to regularly collect and visualize these metrics. Plotting trends allows you to quickly spot anomalies, seasonality, or shifts in business dynamics.

# Example dataset: business metrics over time
data = {
    "date": pd.date_range(start="2024-01-01", periods=12, freq="ME"),
    "DAU": [1200, 1250, 1300, 1400, 1450, 1500, 1550, 1520, 1480, 1550, 1600, 1650],
    "revenue": [10000, 10500, 11000, 12000, 12500, 13000, 13200, 12800, 12600, 13400, 14000, 14500],
    "churn": [0.07, 0.065, 0.06, 0.058, 0.055, 0.053, 0.054, 0.056, 0.058, 0.052, 0.05, 0.049],
    "NPS": [32, 34, 36, 38, 37, 40, 41, 39, 38, 42, 45, 46]

df = pd.DataFrame(data)

# Plot trends for each metric
fig, axs = plt.subplots(2, 2, figsize=(12, 8))
axs = axs.flatten()

metrics = ["DAU", "revenue", "churn", "NPS"]
titles = ["Daily Active Users", "Revenue", "Churn Rate", "Net Promoter Score"]

for i, metric in enumerate(metrics):
    axs[i].plot(df["date"], df[metric], marker="o")
    axs[i].set_title(titles[i])
    axs[i].set_xlabel("Date")
    axs[i].set_ylabel(metric)
    axs[i].grid(True)

plt.show()


              1234567891011121314
            
import pandas as pd

# Using the same dataset from before
# Calculate correlation matrix
correlation = df[["DAU", "revenue", "churn", "NPS"]].corr()

print("Correlation matrix:")
print(correlation)

# Identify leading and lagging indicators
# Example: Check if DAU changes precede revenue changes (simple shift)
df["DAU_shifted"] = df["DAU"].shift(1)
lead_corr = df[["DAU_shifted", "revenue"]].corr().iloc[0, 1]
print(f"\nCorrelation between previous month's DAU and current revenue: {lead_corr:.2f}")

By systematically analyzing business metrics, you can uncover relationships and patterns that drive performance. Correlation analysis helps you understand which metrics may influence others, highlighting possible leading or lagging indicators. For example, a strong correlation between DAU and future revenue can suggest that growing your user base will likely result in increased sales. Regularly reviewing these insights allows you to adjust your strategies, set realistic targets, and focus on the most impactful areas for ongoing business improvement.
