SAB4_#57Lista_activities_vs_WBS

1. Activity List

   • Activity List is a table of schedule activities that has a sufficiently detailed scope of work description along with an activity identifier.
   • An Activity List is a list of the activities we will engage in during the project.
     • the Activity List is best prepared by the actual workers who will be doing the work. If they describe how they will do their own work
       • As team members prepare the activity list, they get highly motivated and focused, so the project is on its way to success.
   • The Activity list must be prepared so that we can create our PERT chart. The activity list and the Gantt define the tasks needed to deliver each component and work package in the WBS.
   • the activity list and the Gantt chart correspond to the project time management process.

2. WBS

   • deliverable oriented hierarchical decomposition of the work to be executed by the project team." 
   • A WBS is a list of the components of the deliverable.
     • the work of building the WBS is done primarily by the project manager
   • The WBS is created as the finest level detail of defined project scope, after progressive elaboration. It completes our work on scope planning, and prepares us to plan all eight other areas of project management, including time. And the first step in detailed time and cost estimation is the creation of the Activity List.
   • In construction, the WBS is made by the architectural designer on his team. Then the general contractor will check and modify the WBS, and, working with the actual construction foremen, develop the Activity List.

3. the right order is: Make the Work Breakdown Structure first, and make the Activity List second.

   • The WBS has to do with the WHAT of the project, while the schedule has to do with WHEN and HOW.
