Definition:
The latest time an activity can begin without delaying the overall project schedule.
Key Components:
- Critical Path Consideration: Determines the latest safe start time for tasks.
- Float Dependency: Non-critical tasks may have flexibility.
- Schedule Optimization: Helps balance workload distribution.
Use Cases/Industries:
- Construction: Scheduling flooring installation as late as possible without delaying occupancy.
- Energy Sector: Starting transformer commissioning just before the grid connection deadline.
- Manufacturing: Postponing raw material procurement while avoiding production delays.
Advantages:
- Reduces unnecessary early resource allocation.
- Helps optimize scheduling flexibility.
- Prevents bottlenecks by delaying non-critical tasks when necessary.
Challenges:
- Delaying too much may introduce unexpected risks.
- Changes in dependent tasks can shift the late start date.

Example:
A pipeline welding task has an early start date of May 1, but its late start date is May 10, meaning it can be delayed up to that point without affecting the final project completion.
