The Work Breakdown Structure $($WBS$)$

Background

The Work Breakdown Structure $($WBS$)$ The first essential component in an integrated approach to developing cash flows is the work breakdown structure $($WBS$).$ The WBS is a basic tool in project management and is a vital aid in an engineering economy study. The WBS serves as a framework for defining all project work elements and their interrelationships, collecting and organizing information, developing relevant cost and revenue data, and integrating project management activities.

The activities below are the DE Manufacturing of Computers Company

Remove fasteners or screws.

Remove the metal casing.

Unfasten $CD$ drive.

Remove support and floppy drive.

Remove power and data cables from the power supply.

Remove the motherboard.

Unfastened drive housing.

Remove rubber feet.

d$-$ Critical Path and Total Float $("$Slack$")$

e$-$ Total Float $("$Slack$")$

f$-$ Using Microsoft Project $($Gantt chart$)$ or Excel for the project plan.

g$-$ Conclusion: Program Evaluation and Review technique $($PERT$)$ during the circle of initiating, Planning, Execution or Operation, Monitoring, and Closing.
