Planning Using Primavera SureTrak Project Manager Version 3.0 Revised 2006

Activity codes may be used to sort, select, summarize and group activities under headings that may be displayed as bands. They are used to present different views of your project during planning, scheduling and statusing. These headings are often based on your Work Breakdown Structures (WBS) and/or Organization Breakdown Structure (OBS).
Defining the code structure can be a major task for project managers. The establishment of templates may make this simpler as your organizations standard codes are then predefined and do not have to be typed in or transferred from another project.
Breakdown Structure
Projects should be broken up into manageable areas by using a Work Breakdown Structure and is usually based on a breakdown of the project deliverables.
SureTrak Activity Codes are created to reflect the breakdown or a project. A code would be created for each level in the WBS and values assigned to represent the components of the project. These values are then assigned to each activity allowing it to be grouped with other activities belonging to the same component.
Organization Breakdown Structure
Organization Breakdown Structure (OBS) is a term used to describe reporting hierarchy of people with areas of responsibility just like an organization chart within a company. Again, SureTrak Activity Codes are created for each level of the hierarchy and values assigned to reflect the various positions and roles. These values are then assigned to each activity for grouping together.
Other Breakdown Structures
Other common breakdown structures in use are:
