First of all, float and slack are two words that mean the same thing it is perfectly fine to use either term in project management float is a measure of flexibility in the project schedule.

A latest start schedule for the example project (within a predefined project deadline of 19 time periods) slack calculations in table 1, the earliest and latest start and finish times are displayed for the project network of figure 1 under two scenarios. Free slack is the amount of time in a schedule that can be taken before the next task is delayed total slack is the amount of time in a schedule that a task can be delayed before an entire project's completion date is delayed. The basic foundation of managing a project is creating an efficient and realistic project schedule during project planning, the pm is given the chance to give it some fine-tuning this is the best time for him to be creative as he identifies the best strategy for completing the project.

Slack for project management slack helps project managers run projects efficiently without compromising quality learn how you can use slack to keep your entire project team (and stakeholders) in the loop at all times — without overloading them with unnecessary emails and meetings. The difference between that early project completion date and the project's contractual completion date - variously called project float, terminal float, terminal buffer, or project schedule margin - is essentially a risk buffer for absorbing critical path slippage within the contract time. Scheduling is one of the first and most important aspects of getting your project started on the right track in the following video, jennifer bridges, pmp, explores the right way to schedule a project’s activities, estimates, dependencies and resources. 10 project schedule planning bpayne and adrienne watt in order to develop our schedule, we first need to define the activities, sequence them in the right order, estimate the resources needed, and estimate the time it will take to complete the tasks.

Pmbok ® guide definition logical relationship: a dependency between two project schedule activities, or between a project schedule activity and a schedule milestonethe four possible types of logical relationships are: finish-to-start, finish-to-finish, start-to-start, and start-to-finish. This gives the schedule more 'slack' you may then utilize the other relationships as ways to shrink the duration of the overall schedule if you use finish-to-start and as soon as possible, you will be able to change the schedule in project insight, project management software , with just a couple of mouse clicks.

In this lesson you will learn about project scheduling and how to include items such as total slack, critical path, and free slack you will also learn the outputs of schedule planning. This can be a predefined delay which is required to put in between the activities to fine tune the project and to meet the quality classic example of this is we need lag between plaster of wall and paint so that cement can set up first.

Lag is sometimes inserted into the scheduling of an activity in cases in which the project work components require overlapping personnel requirements and there is a need to build in a delay to assure that the succeeding activity is properly manned and properly staffed.

A lead/lag should only be used for an unchanging period of time that occurs between one activity and another and a lead/lag should not take resources so, they work perfect to model situations like you metioned (paint drying) and not for introducing delays. When it comes to project activity management, activity sequencing is one of the main tasks among many other parameters, float is one of the key concepts used in project scheduling float can be used to facilitate the freedom for a particular task let's have a look at the float in detail the float.
