🔹 What is Software Measurement?

Software Measurement ka matlab hai software process, product, ya project ke kisi aspect ko quantitatively (numbers ke form me) measure karna.
👉 Ye measurement help karta hai quality improve karne, project progress track karne, aur decision making me.

🔹 What are Software Metrics?

Software Metrics wo parameters hote hain jo software ke quality, complexity, performance, aur maintainability ko evaluate karne ke liye use hote hain.

---

🔹 Types of Software Metrics

1. Product Metrics

• Software product ke features aur quality ko measure karte hain.
  📌 Examples:

• Lines of Code (LOC)

• Function Points

• Cyclomatic Complexity

• Defect Density

---

2. Process Metrics

• Software development process ki efficiency aur effectiveness ko measure karte hain.
  📌 Examples:

• Defect Removal Efficiency (DRE)

• Effort (person-hours)

• Schedule Variance

• Cost of Quality

---

3. Project Metrics

• Project management aur overall progress track karne ke liye use hote hain.
  📌 Examples:

• Effort Estimation

• Productivity (LOC per developer per month)

• Team Velocity (Agile projects me)

• Budget Variance

---

🔹 Importance of Software Metrics

• ✅ Quality Assurance – Defects aur bugs track karne me madad

• ✅ Productivity Measurement – Developer/team ke efficiency ka pata chalta hai

• ✅ Project Control – Time, cost aur resources manage karna easy hota hai

• ✅ Decision Making – Data-driven choices liye jaa sakte hain

🔹 Real-World Example

Online Banking App

• Product Metric: Lines of Code = 50,000 LOC

• Process Metric: Defect Removal Efficiency = 92%

• Project Metric: Development completed 2 weeks before schedule

👉 Ye metrics show karte hain ki project high quality, efficient aur cost-effective tha.

🔹 Summary

• Measurement → Collecting numerical data about software.

• Metrics → Interpreting those numbers for quality & performance analysis.

• Metrics help in → Better quality, cost control, and successful project delivery.
