Testing Estimation Interview Question:

Explain Work Breakdown Structure (WBS)?

Submitted by: Administrator

A big project is made manageable by first breaking it down into individual components in a hierarchical structure, known as the Work breakdown structure, or the WBS.

The WBS helps to project manager and the team to create the task scheduling, detailed cost estimation of the project. By using the WBS motions, the project manager and team will have a pretty good idea whether or not they've captured all the necessary tasks, based on the project requirements, which are going to need to happen to get the job done.

In this technique the complex project is divided into smaller pieces. The modules are divided into smaller sub-modules. Each sub-modules are further divided into functionality. And each functionality can be divided into sub-functionalities. After breakdown the work all functionality should review to check whether each & every functionality is covered in the WBS.

Using this you can easily figure out the what all task needs to completed & they are breakdown into details task so estimation to details task would be more easier than estimating overall Complex project at one shot.

Work Breakdown Structure has four key benefits:

Work Breakdown Structure forces the team to create detailed steps:
In The WBS all steps required to build or deliver the service are divided into detailed task by Project manager, Team and customer. It helps to raise the critical issues early on, narrow down the scope of the project and create a dialogue which will help make clear bring out assumptions, ambiguities, narrow the scope of the project, and raise critical issues early on.
Work Breakdown Structure help to improve the schedule and budget.
WBS enables you to make an effective schedule and good budget plans. As all tasks are already available so it helps in generating a meaningful schedule and makes scheming a reliable budget easier.
Work Breakdown Structure creates accountability
The level of details task breakdown helps to assign particular module task to individual, which makes easier to hold person accountable to complete the task. Also the detailed task in WBS, people cannot allow hiding under the “cover of broadness.”
Work Breakdown Structure creation breeds commitment
The process of developing and completing a WBS breed excitement and commitment. Although the project manager will often develop the high-level WBS, he will seek the participation of his core team to flesh out the extreme detail of the WBS. This participation will spark involvement in the project.
