Developing a Work-Breakdown Structure (WBS) for an Enterprise-wide Wireless LAN

Developing a Work-Breakdown Structure (WBS) for an
Debra, the project manager developing the project plan and feasibility study for the
wireless LAN, received acceptance of the project scope from upper management of
the manufacturing company. She is now ready to develop a WBS identifying the necessary
actions the project needs to accomplish.
The following list gives an overview of each phase of WarehouseTrack:
• Requirements phase—Defines the needs of the eventual users of the wireless
LAN and existing systems (if any). This phase provides the basis for the solution.
• Design phase—Consists of selecting a set of technologies, standards, and products
that satisfy the requirements.
• Development phase—Consists of developing application and connectivity software
that resides on the appliances and server.
• Operational support preparation phase—Consists of the planning necessary to
effectively support the system after it is installed. Preparations include training
development and delivery, and plans for support elements, such as maintenance,
system administration, and security.
• Installation and testing phase—Consists of physically installing the system components
and running tests to verify proper operation.
The following represents a WBS for the implementation of the wireless LAN:
1. Requirements phase
1.1 Elicit end user information
1.2 Elicit system information
1.3 Define the requirements
1.4 Update the project plan
2. Design phase

4. Operational support preparation phase
4.1 Prepare training courses
4.2 Define system administration staffing and procedures
4.3 Establish help desk support
4.4 Define network-management methods and procedures
4.5 Establish a maintenance process
4.6 Define configuration control procedures
5. Installation and testing phase
5.1 Plan the installation
5.2 Stage system components
5.3 Install the components
5.4 Test the installation
