How to Create a Project WBS in Primavera P6 Version 8.2

Project Planning and Control Using Oracle Primavera P6 - Version 8.2 EPPM WebCreating a Primavera P6 Version 8.2 Project WBS

A WBS Node is a term used by Primavera that is often called a WBS Code and is a single point in the WBS structure that activities are assigned to. A Primavera WBS Node may record more information than P3, SureTrak, or Microsoft Project including the following data:

  • Anticipated Dates, which are used to create a bar in the WBS Window when there are no activities under the WBS Node, but do not summarize in the Projects Window.
  • Notes, which are recorded under Notebook Topics,
  • Budget, Spending Plan and Budget Change Log,
  • WBS Milestones, which may be used for assigning progress at WBS Node,
  • WP & Docs that provide links to documents, and
  • The rules for calculating Earned Value for each WBS Node.

[like_to_read]The start and finish dates of a WBS Node are adopted from the earliest start date and latest finish date of the detailed activities under that WBS Node and use the WBS Anticipated Dates to create a bar when there are no activities assigned to a WBS Node.

The duration of a WBS Node is calculated from the start and finish dates, the database Default Calendar and the User Options.

The Project WBS function is designed to record a hierarchical WBS that has been developed on a traditional basis as outlined in many project management documents. A well-structured WBS should:

  • Include all the project deliverables, and
  • Be set at the appropriate level for summarizing project activities and reporting project progress.

The Project WBS function is used to group and summarize activities under a hierarchical structure in the same way as the WBS function in P3 and SureTrak, and the Custom Outline Codes in Microsoft Project.

It is also similar to Outlining in all versions of Microsoft Project; however, in Primavera the Activities are assigned to a hierarchical WBS Node and are not demoted under a Parent task as with Outlining with Microsoft Project. The WBS structure is used to organize and summarize your project activities, including costs and resources during the planning, scheduling, and updating of Projects.

The project should be granulated (broken down) into manageable areas by using a project breakdown structure based on attributes of the project such as the Phases or Stages, Systems and Subsystems, Processes, Disciplines or Trades, and Areas or Locations of work. These headings are normally the basis of the project breakdown structure and are used to create the Primavera WBS structure, and the WBS should present the primary view of your project.

Defining the project breakdown structure may be a major task for project managers.

Primavera also has an Activity Code function similar to the Activity Code function in Primavera P3 and SureTrak software, Codes in Asta Powerproject and the Custom Outline Codes in Microsoft Project.

This feature enables the grouping of activities under headings other than the “WBS Structure.” Unlike in Primavera P3 and SureTrak software, Activity Codes are not the primary method of organizing activities in Primavera.

Topic Menu Command
  • Creating and Deleting a WBS Node
The menu commands Add, Delete, Copy, Cut and Paste all work to create, delete, move, and copy WBS Nodes.
  • WBS Categories
WBS Categories are created in Professional P6 using the Admin, Admin Categories…, WBS Categories tab and are assigned to WBS Nodes by inserting the WBS Categories column in the WBS Window.
