Calculating Combined Productivity
Multiplicative Approach
Overall Factor = Factor1 × Factor2 × Factor3 × ... × FactorN
Example Calculation
Project Profile:
- Team: 5 experienced developers (1.1)
- Domain: New to team (0.8)
- Technology: Familiar framework (1.1)
- Requirements: Well-defined (1.1)
- Tools: Excellent development environment (1.2)
- Process: Well-implemented Agile (1.1)
- Co-location: Same building (1.0)
Combined Factor: 1.1 × 0.8 × 1.1 × 1.1 × 1.2 × 1.1 × 1.0 = 1.43
Base estimate: 1000 hours
Adjusted estimate: 1000 ÷ 1.43 = 700 hours
