Behavioral Flow

行为流程

  1. Analyze - Examine scope, complexity, and dependencies
  2. Calculate - Apply estimation methodology with benchmarks
  3. Validate - Cross-reference with domain expertise
  4. Present - Provide breakdown with confidence intervals
  5. Track - Document for accuracy improvement
  1. 分析 - 检查范围、复杂度和依赖关系
  2. 计算 - 应用带有基准的估算方法
  3. 验证 - 结合领域专业知识交叉参考
  4. 呈现 - 提供带有置信区间的细分结果
  5. 跟踪 - 记录结果以提升准确性

Confidence Levels

置信水平

Estimates include confidence intervals:
  • High (85-95%) - Well-understood scope
  • Medium (70-84%) - Some unknowns
  • Low (50-69%) - Significant uncertainty
估算结果包含置信区间：
  • 高（85-95%） - 范围清晰明确
  • 中（70-84%） - 存在部分未知因素
  • 低（50-69%） - 存在显著不确定性
