start to relationship in project management

Building relationships is as important within the project team as it is But relationships really count when the project or related activities start to. The start-to-finish relationship seems to be the model that causes the most confusion for students of the Project Management Professional (PMP)® exam. The least common relationship is the start-to-finish relationship. Project Insight, project management software, supports all four dependency relationships.

A lead has the opposite effect on the schedule. A lead is the amount of time that a task can start before the completion of the first task.

Many schedulers refer to lead as a negative lag. Note that the use of leads is discouraged by scheduling guidelines. These summary tasks are elements of the work breakdown structure, and will not have assigned relationships.

This relationship assignment has no lag, so leave the lag as 0d. Next select the Task tab, Schedule ribbon group, and link icon, Figure 7. Your Finish-to-Start relationship for these two tasks is applied as displayed in Figure 8. Figure 9 Again, your tasks with the Finish-to-Start relationship will be as shown in Figure Figure 11 The result is in Figure This is the input for the standard business time lag. However, our lag is not standard.

In the Lag column of the Task Information dialog for Predecessors, Figure 13, type in 5ed, which stands for five elapsed days. Figure 13 Click OK, and your elapsed time lag will be as displayed in Figure Figure 14 Assigning a Finish-to-Finish Relationship Now we are going to assign two tasks a Finish-to-Start relationship, and edit it to make the relationship Finish-to-Finish.

Figure 15 Next double click on the Gantt chart relationship arrow connecting the two tasks, and the Task Dependency dialog shall appear, Figure The Insulate Piping task and associated relationships will be as shown in Figure Figure 18 So the Insulate Piping task may commence after the completion of the Test Piping System at Pressure task and completes shortly after the completion of the Strike Forms task.

The Finish-to-Finish FF relationship allowed us to begin insulation of the piping while waiting for the concrete to cure. It, thus, enabled us to compress the schedule by performing tasks in parallel, which is called fast tracking.

Round Out the Schedule Complete the schedule by assigning a Finish-to-Start relationship between the remaining tasks, Figure The project with assigned relationships will be as displayed in Figure Figure 19 Now select the Format tab, Bar Styles ribbon group, and Critical Tasks to display the schedule with critical path, Figure Figure 20 You now have the true length of the schedule, which is compressed slightly via the tasks performed in parallel.

Summary Microsoft Project provides four types of relationships between tasks, allowing you to model tasks both in series and parallel. The critical chain method necessitates taking into account resource constraint-derived dependencies as well. Leads and Lags[ edit ] Dependencies can be modified by leads, and lags. Both leads and lags can be applied to all 4 types of dependencies. PMBOK defines lag as "the amount of time whereby a successor activity will be delayed with respect to a predecessor activity".

When building two walls from a novel design, one might start the second wall 2 days after the first so that the second team can learn from the first. This is an example of a lag in a Start-Start relationship.

In accordance to PMBOK a lead is "the amount of time whereby a successor activity can be advanced with respect to a predecessor activity For example, on a project to construct a new office building, the landscaping could be scheduled to start prior to the scheduled punch list completion. This would be shown as a finish-to-start with two-week lead".

It would be much faster and less expensive, to install the pipes first, place the concrete to actually build the wall around the pipes, and finally paint the walls. Shoring of the trench has to be done not necessarily immediately after excavation, but within certain time, otherwise the trench will collapse. Vaccination of baby has to be done not immediately after birth, but within certain time Renewal of the passport has to be done some time after the current one has been issued, but before it expires.
