work from slipping through cracks Provide the big picture to the project team and where their works fit

1 Project Scope Management Work Breakdown Structure (WBS) Created in Planning Process -> Scope Area Benefits of Work Breakdown Structure Organizes and defines the total scope of the project Helps prevent work from slipping through cracks Provide the big picture to the project team and where their works fit in Gets team buy-in and builds the team Facilitates communication and cooperation Is the foundation of the project

Package Work not in the WBS is outside the scope of the project

2 Work Breakdown Structure (WBS) Work Breakdown Structure (WBS) Breaks the project into smaller and more manageable pieces called Work Package Work not in the WBS is outside the scope of the project Decomposition approach: Functional Lifecycle/ Phase Product component/ Deliverable

8 Project Scheduling Critical Path Method (CPM) Is a project network analysis technique used to predict total project duration Calculates the shortest time necessary to complete a project Uses Most likely duration Identified by calculating the earliest and latest start and end dates for every task The Critical Path is the route with zero float (slack) Project Scheduling Float (Slack) the amount of time you can delay the activity with no affect to other parts Total Float (TF) = the amount of time you can delay the earliest start of a task without delaying the ending of the project (Formula: TF = LS-ES) Free Float (FF) Project Float Forward Pass - ES, EF; Backward Pass LS, LF Backward Pass Forward Pass
