What Is a Key Worker?
In the dual code network plan, the key work is the work with the smallest total time difference. The job with the smallest difference between the latest completion time and the earliest completion time or the smallest difference between the latest start time and the earliest start time is the job with the smallest total time difference, which is the key job.

- In the dual code network plan, the key work is the work with the smallest total time difference. The job with the smallest difference between the latest completion time and the earliest completion time or the smallest difference between the latest start time and the earliest start time is the job with the smallest total time difference, which is the key job.
- The critical work is connected end to end, which constitutes the path from the start node to the end node. The total duration of each task on this path is the largest. This path is the key line. There may be virtual work on critical lines.
- The nodes at both ends of the critical work must be critical nodes, but the work at both ends of which is a critical node is not necessarily critical work.
- Critical and non-critical tasks
- The key work is the focus of progress control. Once the key work is delayed, it will inevitably lead to the delay of the entire progress. Therefore, controlling the progress of key work also controls the construction progress. Although non-critical work is not the focus of schedule control, when the delay of non-critical work exceeds the total time difference, it will be converted into critical work. Therefore, due attention should be paid to non-critical work with a small total time difference.
