WBS is also used to control access within a project. Similarly, this summarizing of data will enable you to monitor, control and report at any WBS level. You can easily see this required information if you have elements of earthworks and electrical works in your WBS. For example you may want to see what is the total duration of all earthworks in your schedule or you may want to see what is the total or actual cost of all electrical works of you project. This data can be with respect to duration, cost or resources. This means that you can summarize your data at any WBS level. WBS is used to view combined data of activities. For example if I have to update brickwork on lets say 10 th storey of a 15 storey building in my schedule then it is difficult to find this particular activity if they are not organized. It is important to organize them so that they are easily accessible and also we can communicate about activities better if they are well organized. Projects have a large number of activities.

WBS is used to organize activities of a project. Your estimates will be more accurate and you will be more confident about your planning. It is easy to plan a component of a project rather than planning a project as a whole. WBS is used to plan scope, time, resources and cost of the project. So in this example, our WBS level 2 contains the work packages. WBS elements which contain activities are also called work packages. Now we can place activities in our lowest level of WBS. We can sub divide them further if it is needed. Similarly, we can also divide first floor and roof. We can divide ground floor in to structure works, architecture works, electrical works and mechanical & plumbing works. Then we can divide these elements further according to nature of work for example we can divide foundations in earthworks and structure works. We can divide this project in to Foundations, Ground Floor, First Floor and Roof which is our 1 st level of WBS. This is a project title which is construction of a 2 storey building.
