How to prepare the project activity list?

• The Work Breakdown Structure depicts the main project components. It has the project on the top of the hierarchy, followed by main project phases and primary components expressed as deliverables.
• The primary deliverables are then further broken down in smaller deliverables, a.k.a. sub-deliverables.
• Then break down the sub-deliverables again until suitable manageable units usually called lowest level sub-deliverables.
• The WBS components are identified by numbers from the top, the project, to the lowest level deliverables as shown 1, then 1.1, then 1.1.1. 1.1.2, and so on.
• The project tasks are determined based on work required to complete and deliver the WBS lowest level sub-deliverables. They are also called work packages, in which the task detail information, resources, budget, and estimates are described.
• The project activity list is derived from the from WBS lowest level sub-deliverables. You need to describe the principal information about the tasks such as WBS ID, task ID, task name, the estimated duration, and predecessors.
• The tasks names are different of the deliverables. The deliverable title must be a noun or compound noun, while the task title must have an action verb.

What is a Project network diagram?

• It is an illustration of the sequence of work in a project.
• There is a work sequence because some activities can just be executed after previous activities are completed – a.k.a. predecessors.
• Some activities do not require previous work, and they do not have predecessors.
• The most common way to show the activities sequence is called Precedence Diagramming Method (PDM)
•

How to prepare a Precedence diagram?

• Contact the project team and discuss with the person in charge for a task, what task or tasks must be done before he starts his tasks. Include the task or tasks ID in the predecessor column,
• After filling out the predecessors for all tasks, it is time to draw the precedence diagram.
• Start with task or tasks without predecessor and place them on the left side.
