These times are calculated using the expected time for the relevant activities. The earliest start and finish times of each activity are determined by working forward through the network and determining the earliest time at which an activity can start and finish considering its predecessor activities. The latest start and finish times are the latest times that an activity can start and finish without delaying the project.
LS and LF are found by working backward through the network. The difference in the latest and earliest finish of each activity is that activity's slack. The critical path then is the path through the network in which none of the activities have slack. The variance in the project completion time can be calculated by summing the variances in the completion times of the activities in the critical path.
Given this variance, one can calculate the probability that the project will be completed by a certain date assuming a normal probability distribution for the critical path. The normal distribution assumption holds if the number of activities in the path is large enough for the central limit theorem to be applied. Gantt charts are used to show calendar time task assignments in days, weeks or months.
The tool uses graphic representations to show start, elapsed, and completion times of each task within a project. Gantt charts are ideal for tracking progress.
The number of days actually required to complete a task that reaches a milestone can be compared with the planned or estimated number. The actual workdays, from actual start to actual finish, are plotted below the scheduled days. This information helps target potential timeline slippage or failure points. These charts serve as a valuable budgeting tool and can show dollars allocated versus dollars spent.
To draw up a Gantt chart, follow these steps:[ 1 ]. Benefits of using a Gantt chart include:[ 8 ]. Since operations managers are responsible for planning, projecting, and analyzing various aspects related to production, they are very dependent on the accuracy of the data. With an ERP system, operations managers can generate accurate real-time data related to inventory, production, and sales.
This system also allows inter-departmental integration so employees from different divisions and even locations can collaborate with each other through the same system. Save my name, email, and website in this browser for the next time I comment.
