	A common tool for visualizing a Work Breakdown Structures is by using a Gantt Chart. This schedule is waterfall based and provides a great overview of the sub-projects in a perspective of time as this kind of schedule works as a timeline. The Gantt Chart is a schedule in which all of the sub-projects or deliverables are listed vertical often with a planned start- and -end date, cost estimation, person responsible for the task and an actual cost of the task. Horizontally on the chart is a calendar in which it is marked for each sub-project when the work is planned to be done.

	To implement a Gantt Chart, the project must of course be divided into smaller projects or sub-goals. These tasks are then organized in area of work, contact person and firm. It is also important to state who is responsible for the sub-goal to be finished to the expected time and at the agreed quality. Then this is examined, it is identified if any of the works or sub-goals or deliverables are overlapping and which of the works that are depending on each other. These works must be done in a certain order. After this identification, the time estimated for each work is determined and the works are ready to be scheduled.[8]		To implement a Gantt Chart, the project must of course be divided into smaller projects or sub-goals.

	The Work Breakdown Structure should be implemented in the planning of the execution of a project. To what extent the work should be broken down and the level of details ~~planed~~ in every work package or sub-project depends on the size of the project. The bigger the project is, the more risks will occur. The more risks in the project, the more planning is needed in order to fulfil the project scope to a satisfactory extend. When something goes wrong, it must be detected as quickly as possible and dealt with. This is easier if the work and project is scheduled to a proper degree of details for the size of the project.[2]		The Work Breakdown Structure should be implemented in the planning of the execution of a project.

	Common for all Work Breakdown Structures is that the sub-projects should be deliverables or outcomes, and not on actions. This ensures that the sub-projects are manageable, definable, estimable, and measurable. For instance; if the overall project is renovating a bathroom, one of the sub-projects would be to install a new toilet. This task is definable in the way that it is easily understood by the ones working on the renovation: the toilet must be set up and installed. The task is manageable because the responsibility of setting up and installing the toilet can be handed out to a person with the ability to do it. The task is estimable because the time used to set up and install the toilet can be estimated as well as the expenses for the workforce and the resources. Last but not least, the task is measurable because the task will result in a physical installation when done and the time used on the task can be measured as the timespan from the beginning of the task till the end of the task.

	The waterfall structure in figure 1 illustrates how a process will lead to another process ~~with~~ is often the case in projects. In a building project for instance certain sub-projects must be done in other to move on to new sub-projects. If the project is to renovate a roof on a house, a scaffold must be mounted before the work on the roof can be started. The tree structure on the right side of figure 1 shows a project scope on top of the schedule. Underneath the scope is broken down into smaller works, that is needed to fulfil the overall scope of the project. These smaller works are again broken down into smaller works and analyzed for cost and work.

			A common tool for visualizing a Work Breakdown Structures is by using a Gantt Chart. This schedule is waterfall based and provides a great overview of the sub-projects in a perspective of time as this kind of schedule works as a timeline. The Gantt Chart is a schedule in which all of the sub-projects or deliverables are listed vertical often with a planned start- and -end date, cost estimation, person responsible for the task and an actual cost of the task. Horizontally on the chart is a calendar in which it is marked for each sub-project when the work is planned to be done. [8][9]

			To implement a Gantt Chart, the project must of course be divided into smaller projects or sub-goals. These tasks are then organized in area of work, contact person and firm. It is also important to state who is responsible for the sub-goal to be finished to the expected time and at the agreed quality. Then this is examined, it is identified if any of the works or sub-goals or deliverables are overlapping and which of the works that are depending on each other. These works must be done in a certain order. After this identification, the time estimated for each work is determined and the works are ready to be scheduled.[8]
			This can be done in two ways; Firstly, it can be done from the starting point of the project. The works are then scheduled from a date and forward until the estimated time for the given work is up. This step needs to take in to account, that holidays may occur in the timespan of the project. When a deadline is set for one sub-project, the next sub-project dependent on the first sub-project can be scheduled and so on. The second way to do the time-scheduling is to begin from the deadline of the project and do the scheduling backwards. This is a good way to optimate the timespan of a project, because this provides the project manager with the fasted time schedule in a natural way. An example of a Gantt Chart can be seen in figure 2.

	To summarize: The Work Breakdown Structure is a good way to make a sound estimation of a project in terms of timespan and budged. But as a rule of thumb, something will deviate from the project plan at some point doing a project. A good Work Breakdown Structure schedule will provide an overview for the project manager, who in case of deviation from the schedule can act on them at an early state and reduce any harm to either the product delivered in the end, the time schedule, or the budget. As so, a Work Breakdown Structure can be seen as a work in progress and not a finished product.
