Hubungan Ketergantungan antar Aktivitas

2. Bentuk Hubungan Antar Aktivitas

Gunakan Lag time untuk overlap atau delay.

dalam "Finish-to-Start" relationship, successor tidak bisa mulai sampai predecessor selesai dilaksanakan

Dalam hubungan "Start-to-Start" relationship, successor tidak boleh mulai sampai predecessor mulai

dalam ketergantungan "Finish-to-Finish" , successor tidak boleh selesai sampai aktivitas predecessor selesai.

Gunakan Lead time untuk menjadualkan kegiatan lebih awal

2. Check hubungan antar aktivitas melalui Relationship Diagram

Relationship diagram is a special version of Network Diagram

While working on a large project, this graphic view helps you to focus on one task and the tasks to which it is linked.

This view displays the current task in the center of the pane

If a conflict exists, caused by multiple dependencies or a combination of dependencies and constraints , Project will give you this warning.

3. Peringatan bila terjadi Conflict akibat pola hubungan antar aktivitas

Change the conditions that make the successor task dates fixed

Remove the relationship definition so that a successor relationship to the task in the message no longer exist

Change the conditions governing the finish date for the predecessor (the task named in the late date message) so that you can schedule the task to finish by the late date.

4. Tips bila terjadi Activity Dependency Conflict

Identifying the Critical Path.

Crashing the Schedule :

•Review with an intent to reduce task duration that are unnecessary long

•Examine the predecessor and successor relationships and try to identify the relationship that can change from Finish to Start to one of the overlapping relationship (SS,FF, Lead-Lag schedule)

•Increase Resource Assignment for task that are not fix-duration tasks.

6. Melihat Schedule dalam bentuk Calender & Precedence Diagram

Calendar view is useful when entering a simple project and reviewing what needs to be done on a specific day

The Network Diagram view displays the general flow of work and the relationships between the tasks of your project

Specify how large or small you would like to view the diagram.
