In project management, Slack isn't the popular communication app you might be thinking of! Here, Slack refers to the buffer time you have for a task before it delays the entire project. It's essentially the wiggle room you have to absorb unexpected setbacks without throwing the whole schedule off track.
Think of it like this: imagine a project as a train journey. Each task is a stop along the way. Ideally, everything runs smoothly, and the train arrives on time. But sometimes, delays happen (like waiting for a new part or clarifying requirements). That's where Slack comes in. It's the extra time built into your schedule to account for these bumps in the road, ensuring your train (project) arrives on time.
There's no magic number for ideal Slack time. It depends on your project's complexity, dependencies between tasks, and overall risk. However, a good rule of thumb is to aim for 10-20% buffer across your critical tasks. This provides some breathing room without making your schedule excessively loose.

Slack or Float is the amount of time an activity can get delayed without delaying the overall end date of a project
According to Malhortra/Krajewski/Ritzman, In their book "Operations Management", The maximum length of time that a task can be delayed without procrastinating the whole project is called activity slack. Activity on a critical path has Zero slack. Information on slack is useful because it summit activities that call for close attention. In this respect, activity slack is the amount of timetable slippage that can be accepted for an activity before the entire project will be delayed. Slack at an activity is lessened when the assessed time duration of an activity is surpassed or when the planned start time for an activity must be put off because of resource considerations (1). 1- Malhortra Krajewski Ritzman, "Operations Management" , 9th Edition, Prentice Hall, NJ
Total slack refers to the amount of time a task can be delayed without affecting the project's overall timeline. If a task on the critical path has total slack, it means that the project's completion date can be extended without impacting the critical path. This can provide flexibility in managing the project's schedule and resources.
Slack is important when managing a project because it's is very rare that things don't change while working on a project. Budgets change, schedules change, available resources change and so do task priorities. Without slack time it'll be very challenging to be able to manage the project in a flexible way without causing tasks to be stuck or not have time to handle urgent things that were introduced (that weren't planned ahead of time).
Program Management does not equate Project Management. Put it simply, Program Management is about handling multiple projects at the same time to serve a strategic, broader business need, while Project Management is about managing and focusing on (usually) one project at the time. A Program Manager usually oversees Project Managers.
What is slack time in project management
Slack time in operations refers to the amount of time that a task or project can be delayed without affecting the overall schedule or deadline. It is a critical concept in project management and scheduling, allowing for flexibility in resource allocation and task execution. By identifying slack time, managers can better prioritize tasks and optimize workflows, minimizing the risk of delays in project completion.

The critical path is the longest path through a project, indicating the shortest possible time needed to complete the project. Slack time is the amount of time a task can be delayed without delaying the project completion. Tasks on the critical path have zero slack time, while non-critical tasks have slack time.

Free slack: The free slack of an activity is the time this activity can be delayed without impact on the following activity. Total slack: The total slack of an activity is the time this activity can be delayed without impact on the finish date of the project.
Total slack refers to the amount of time a task can be delayed without affecting the project's overall timeline. If a task on the critical path has total slack, it means that the project's completion date can be extended without impacting the critical path.
