如何计算Critical Path
learn.whatIsHeading
Identifies the longest sequence of dependent tasks determining minimum project duration. Changes to critical tasks directly impact completion date.
分步指南
- 1List all project tasks and dependencies
- 2Calculate duration for each task
- 3Find all paths through tasks
- 4Identify longest path (critical path)
- 5Monitor critical tasks closely
例题解析
输入
A→B→C 12days
结果
12 day min
常见错误注意事项
- ✕Not identifying all dependencies
- ✕Assuming adding resources to critical path always helps
常见问题
Why focus on critical path?
Delays on critical tasks delay entire project; non-critical tasks have flexibility.
How do I reduce project duration?
Focus on critical path: parallelize tasks, reduce scope, add resources, reduce dependencies.
