Explanation:
Leads and Lags:
Leads and Lags are types of float. Let’s take an example to understand this.

In project management, there are four types of dependencies:

Finish to Start (FS) – Later task does not start until the previous task is finished
Finish to Finish (FF) – Later task does not finish until the previous task is finished
Start to Start (SS) – Later task does not start until the previous task starts
Start to Finish (SF) – Latter task does not finish before previous task starts

Take the scenario of building two identical walls of the same house using the same material. Let’s say, building the first wall is task A and building the second one is task B. The engineer wants to delay task B for two days. This is due to the fact that the material used for both A and B are a new type, so the engineer wants to learn from A and then apply if there is anything to B. Therefore, the two tasks A and B have a SS relationship.

Conclusion For a project manager, the concepts of float, lead, and lag make a lot of meaning and sense. These aspects of tasks are important in order to calculate project timeline variations and eventually the project completion time.
