Introduction
Analysis of the core framework of the standard
| Module | Measurement method | Benchmark reference | Typical value range |
|---|---|---|---|
| Feasibility study fee | Differential rating progressive method | DB44/T635-2009 | 0.8%-4% |
| Development fee | Function point analysis method | SJ/T 11463-2013 | 6.91ph/FP(P50) |
| Third-party testing fee | Development fee ratio conversion | SSM-BK | 80,000-600,000 yuan |
Key technical points
1. Implementation of function point analysis method
The standard recommends 5 function point measurement methods, among which the NESMA method has significant advantages when the requirements are unclear. Scale adjustment needs to consider:
- Initial function point UFP=35×ILF+15×EIF
- Adjusted scale S=UFP×VAF×RCF
2. Cost structure model
A provincial power dispatching system development case:
Total cost C = feasibility study fee (2.1%) + development fee (62.3%) + third-party testing fee (8.7%) + implementation fee (15.5%) + supervision fee (3.2%) + engineering management fee (8.2%)
Application of industry benchmark data
| City | Man-month rate (10,000 yuan) | Productivity (ph/FP) |
|---|---|---|
| Beijing | 2.57 | 4.56(P25) |
| Chengdu | 1.69 | 6.91(P50) |
Implementation Suggestions
- In the demand phase, the Indicative Function Point Analysis Method
- Safety testing needs to distinguish between secondary/tertiary system requirements
- Construction period compression needs to be evaluated according to the D=1.277×(AE/HM1)0.404 model
