软件健康指数

指标归入加权类别,统一采用 1–100 量表。总体分先取类别加权平均,再依据公开记录的分布进行校准,使各等级具有百分位含义;当公开证据触发高风险司法辖区政策时,评级会按政策调整,并设置 34(存在风险)的上限。

44
卓越93-100公开记录中的最高层级(约前 5%);基本满足所有检验标准
优秀80-92各方面均表现强劲;仅有少量不足
良好65-79健康;不足之处有限且可控
中等50-64可接受,但存在明显不足;建议进行审查
薄弱35-49多个领域存在实质性薄弱环节
存在风险20-34存在重大薄弱环节;采用时应保持审慎
危急1-19问题严重(项目被弃置、仅有单一维护者、缺乏基本工程规范)

评分画像

每条轴代表一个类别。形状比平均值更重要——健康的对象会填满整个图形,而“一峰一谷”式画像意味着某一维度的优势正掩盖另一维度的风险。

加权总体分 46 经校准后在公布的指数量表上为 44(记录校准 2026-08-02)。
