The PMP Certification Exam will ask you about sequencing activities. After identifying all the activities that need to be accomplished, the next step is to put them in order. Sometimes you will order them in conjunction with identifying activities; sometimes you won’t.

All activities should have a predecessor (except the first one), and all activities should have a successor (except the last one). For those activities that take place throughout the project, such as risk management or stakeholder management, you can create an activity that starts at the beginning of the project and goes until completion.

Sequence Activities. The process of identifying and documenting relationships among the project activities.

At this point, you aren’t establishing how long activities will take: only the sequence in which they will occur. To do this, you use all the outputs you generated in the previous processes:

  • Schedule management plan

  • Activity list

  • Activity attribute (if you need these)

  • Milestone list

You may also reference the scope statement in case you have any assumptions or constraints that indicate the order of events. Any information from past projects can be useful as well.

Relationships between activities are logical relationships. This doesn’t mean there are such things as illogical relationships: It simply refers to the way activities are sequenced in relationship to one another. For example, one activity has to end before another can start, or two activities should happen simultaneously.

Logical relationship. A dependency between two activities, or between an activity and a milestone.

The four possible types of relationships are

  • Finish-to-start

  • Finish-to-finish

  • Start-to-start

  • Start-to-finish
