Project Scope Management

[email protected] Co., Ltd

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





•Breaks the project into smaller and more manageablepieces called “Work Package”

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

•Decomposition approach:

• Functional

• Lifecycle/ Phase

• Product component/ Deliverable

Project Time Management


Activity Sequencing

Identifies and documents dependencies among schedule activities

4 Types of dependencies/ relationships

• SS – Start-to-Start

• SF – Start-to-Finish

• FS – Finish-to-Start

• FF – Finish-to-Finish

Dependency Determination

• Mandatory dependencies

• Discretionary dependencies

• External dependencies

Lead and Lag i.e. SSCD = -5d, FSAB = 3d

Uses Network Diagram – AON, AOA


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

a. It makes it easier to manage.

b. It increases the project risk.

c. It requires more people.

d. It makes it more expensive.
