Project Management – Sequence Activities Process

Project Management – Sequence Activities Process
By Marc Derendinger, Northwest University

The sequence activities process takes all the activities you defined in the Define Activities process and orders them by precedence. You are creating a map or diagram that illustrates the relationship between these activities and identifying the order in which they need to be done. It is important to note that you are not creating the schedule itself during this process, and therefore do not assign any start or finish dates to these activities.

Your inputs for this process include: activity list, activity attributes, milestone list, project scope statement and organizational process assets. Your activity list contains your schedule activities and needs to be arranged into the order they should be performed for your diagram. Your activity attributes provides additional insight into which activities need to be performed before others. Your milestone list provides you with key milestones that might influence the order of your activities. Read the Complete Article

Critical Path Mapping with Activity Network Diagrams

Critical Path Mapping with Activity Network Diagrams
By Steven Bonacorsi

The activity network diagram is a method of displaying the timelines of all the various subtasks that are involved in any project. By doing this, the total task duration and the earliest and latest start and finish times for each task are also calculated and displayed. In addition to showing which subtasks are critical to on-time task completion, the activity network diagram can help determine where extra effort to speed a subtask will have the greatest payoff to overall speed.

The activity network diagram has had a relatively long history, dating back to the 1930s. In the 1950s, the technique emerged as the Program Evaluation Research Technique (PERT) and as the Critical Path Method (CPM). There are several ways to represent the output of the PERT/CPM process.

The method called the activity-on-arrow or, more simply, the arrow diagram will be reviewed in this article. Read the Complete Article
