Explanation of the Gantt Chart

interpretation of the Gantt ChartIts use a simple logic calculations to identify the circumstantial way, it does include A sequence of activities has a metre epoch. Adding the timing durations from the kill till the end (forward pass), it helps to determine the too soon and late start. reimburse the timing durations from the end to the start (backward pass), it help to determine the late and early block. Deduct the early fetch up from the late finish, by that we found the total float. The early start for action A is 0, while the late finish for application R is equal to its late start.The over precise pathwayway is the longest grievous of activities in the plat with no flexibility, linked to apiece other without interruption. In other word its the path has activities with total float equal zero.While the duration of the cast off determine by the earliest and late finish of the conclusion operation in the device.Gantt chart is useful tool to start manager, in th is chart there is a calendar time scale enable to determine the project duration including , not only the working solar twenty-four hour periods, still also holydays and weekend.If the project starts on 11 January 2010 in 5 day working week, assuming there is no holidays the earliest day the project will completed is 2 April 2010. (See end of the document).a. As activity P is a comminuted activity in a searing path a one day hold will create a delay in activities Q and R, which delay the project end for one day. withal it could generate an add-on in project cost. The project manager should be able to predict this before its occurred, therefore he should analyses the network diagram and looking for maneuver margin.b. If activity N completed 1 day earlier, it could give other activities in the path such as O, P, Q, and R one day flexibility. However it doesnt mean that the project will finish earlier because other activity recourses were schedule and it could be not easy at t hat time, but still there is possibility to the project to finish 1 day before than schedule.c. Activity I is not critical activity, thats mean it has a float or slack which is in this activity is 6 days. There for a delay for 2 days in this activity will not create a delay in whole project, however there a possibility to generate increase in cost than the pictured before.In the network diagram all the project activities be represent accordance with the relations that exist amid them, the activities represented by nodes (boxes), these mentioned the beginning and the end of each activityThe benefits for the diagram areObtain a schematic representation of the project.predict the compulsory time to complete the project.distinguish between critical and non critical activity in the project, and thus determine the possible maneuver margin for each task, which kitty be by moving some resources from non-critical tasks and focus on critical activity, which contributes to reduce the tim e of the project with a fixed cost.Implementing the network diagram is summarized in these musical notesknow all the activities for the project their is a appoint of all tasks (activities) often included in the outset project ground on Work Breakdown StructureIdentify the relations between these tasks there are tasks that can be implemented in parallel, or may depend on the end of the other tasks (sequence), in this step is a list of all the project tasks and its relations with other tasks. fit the network diagram after knowing the tasks, and the relations with other activities, the project activities are drawn as Node network diagram.Estimate the required time an estimate of required time to complete each activity passed on past experiences, or by using intuition and logic, the estimate may not be free of error.identifying the critical activity and critical path of the project critical activity is an activity which, if the delay occurred during the execution of instrument, it could delay the whole project with the same amount, the critical path is the path that connects critical activities and it starts from the beginning of the project and finished at the end of the project, it is the longest path in terms of length in the network diagram. On this path there is no margin time to maneuver in the implementation of some(prenominal) task because of the lack of flexibility time in any task on this path.Update the network diagram on a regular basis during the implementation of the project, real-time registration is taken for each activity, and in the meantime, critical path may appear to show recent activities were not taken into account.
