It is geared to please the lazy scheduler. This is also mostly implemented across the board and not at the activity level, in both cases a wrong approach, shall not be automated. What blow out our mind is that some PMI members are proponents of the Non Continuous PDM Method, a method that allows for automatic activity spitting, this is wrong in the case you want to keep the activity continuous, this hides that individual segments do have early and late dates and floats of their own. This is not necessarily true after progress is reported or when using non continuous PDM (split activities). Just burn the PMI document as it is inconsistent, at times it defines float using start dates while at times it defines float using finish dates. It is the difference between an activity’s early finish date and the earliest start date of the closest of its successors. Represents the amount of time an activity can delay its early finish without impacting any successor activities early start. It is computed as the difference between the late and early dates of the activity, calculated from the forward and backward passes respectively. Represents the amount of time an activity can delay its finish without impacting the late finish of the project. Free float is calculated by subtracting the early finish date of the activity from the earliest start date of the closest of its successors. Total float is calculated by subtracting the early finish date from the late finish date (start dates can be used instead). Who can tell if my or ur plan are more efficient ?įrom the PMI Practice Standard for Scheduling.įloat values are calculated by comparing the early and late dates as follows:

Who can tell that my plan is better than zaher or samir or mike or x or y plan ?
#What is the slack client programmed in free#
If anyway body think about it will find it not an easy task in fact its the final touch to make ur plan optimizedĬause also so much free time available will reflect on ur resources values and also your project estimated budgetĭuration means time and time means money salaries and wages so anybody here made such optimization? The question is if i know this and i have a feeling about it how can i optimize my plan after i check the slack time and after i see it on the Gantt chart

The machine transport can cause delay or machine erection can make more delay the weather when i left such heavy machine on the roof for example can cause delay If i have an installations to be done in a ceiling of a building and from my site experience i know that such installations needs only 1 week and i give to it 2 weeks so the closing of the ceiling which depend on my finishing of such installations will lose one week cause i over estimate my time which is not wise of course u can cheat any client with it so i know and i feel i need to be realisticīut in the same time with factor of safety in every tasks or if im more specialist with tasks that i know it can cause delay like machine handling to the site The efficiency of your planning of a project is depending and i have feeling of this on the slack time you have so if i made so much slack values this mean im not a good planner cause i allow so much time free time available for every task to have a delay like I dont want a fight here its hard thing to understand even prof planners cant understand

If remaining duration is less than 0.75 days 0 is not an option but fraction of a day might. If required to round remaining durations I would round up greater than 1 day remaining durations to the current integer if fractional is I favor using hours as the planning unit and not be so concerned about the precise hour the activity is scheduled to start because you never know ahead of time the exact hour, better manage on the optimistic schedule than a delayed schedule.This is one of the many reasons why we should schedule considering management of buffer time.On the other hand for many activities it makes perfect sense to start as soon as possible even if it is not at first hour of the work day. No matter what, in practice some activities will be delayed on the field for reasons such as it does not make sense to start the activity if it is not going to be finished the same day, another reason will be after certain hour it does not make sense to start certain activity.Instead of using %duration you can use whole days for remaining duration, but this will have the effect of delaying some unwanted activities.Say 50% duration on a total of 3 days equal 1.5 days. If applying % to total duration it is to be expected to get some fractional days as remaining duration.
