The re-planning of the project shows that the critical path has changed and the project
duration has also increased by 14 days.

4. Maintenance of the original target training date
For maintaining the original target training date, resources will be transferred only within
the available slack and those will be allocated to the critical activities. The levelling of resources
within available slack will help to maintain start date for the training and development project.

1. Critical path
The critical path for this project is A-D-E-G-I-J with a duration of 97 weeks.

Explanation on management of critical path activities
The critical path activities have direct impact on milestones of a project and significant
impact on the end date of a project. The critical activities must be focused more than non-critical
activities as those directly contributes to changes in duration of a project. The critical path of a
project is considered as the shortest path for a project and thus there is a need to manage the
critical activities. The critical path requires closer scrutiny but at the same time other paths have
also to be monitored as those maybe related to the critical path or even may become a critical
path. It is also necessary that project manager should not ignore the non-critical activities while
managing the critical activities. Thus, it is essential that critical path have to be managed
effectively rather than non-critical activities. The critical path is related directly to the overall
project thus changes in the critical activities impacts the entire project.
One such instance of changes in critical activities can be found in Exercise 1 where, it has
been demonstrated that the critical path has changed with duration of “activity a”. Hence,
managing the non-critical activities in the developed schedule will not help to maintain the
original target date. The previously found non-critical activities has become critical activities
after changes in “activity a” thus it is necessary that critical path activities should be managed
differently from non-critical activities.
