《GB/T 36964-2018软件工程 软件开发成本度量规范》由TC28（全国信息技术标准化技术委员会）归口，TC28SC7（全国信息技术标准化技术委员会软件与系统工程分会）执行，主管部门为国家标准化管理委员会。
Introduction
GB/T 36964—2018 Software Development Cost Measurement Specification Interpretation
1. Background and Significance of Standard Formulation
The software engineering field has long lacked a unified cost measurement standard, resulting in many uncertainties in project budgeting, bidding and cost management. The introduction of GB/T 36964—2018 fills this gap and provides a scientific basis for cost estimation, management and control of software development projects.
2. Standard framework comparison table
| Standard dimensions | GB/T 36964—2018 | SJ/T 11463-2013 | International IFPUG method |
|---|---|---|---|
| Cost composition | Human + non-human costs, subdivided into direct and indirect | Basic function scale and workload estimation | Function point method as the core |
| Measurement method | Equation method, analogy method, inference method | Mainly rely on function point analysis | Multi-dimensional benchmark data model |
| Scope of application | Full life cycle, covering budget, bidding and other scenarios | Mainly used in the development stage | Focus on commercial applications and real-time systems |
3. Standard implementation recommendations
(1) Cost estimation and management
Workload estimation:Based on functional scale measurement, combined with benchmark data and adjustment factors. For example, when using the NESMA method for function point counting, the appropriate adjustment factor should be selected according to the project stage (2.0 in the budget stage and 1.26 in the bidding stage).
(2) Bidding and contract management
Evaluation benchmark price setting:Refer to industry benchmark data to ensure a reasonable range. For example, the lowest reasonable bid can be set to the lower limit of the budget (25th percentile), and the highest reasonable bid can be set to the upper limit or the project budget.
