	It is beyond any reasonable doubt that the ''Work Breakdown Structure (WBS)'' is an exceptionally useful tool for planning, estimating, scheduling and controlling any kind of project. The term WBS describes the procedure of subdivision of the project deliverables and workload into smaller more manageable segments. More specifically, “The WBS is a hierarchical decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create the required deliverables.” (PMBOK® Guide-Fifth Edition, 2013, p. 126)<ref name="one">Project Management Institute. “A Guide to the Project Management Body of Knowledge (PMBOK® Guide)”- Fifth Edition, 2013, p.126</ref>		It is beyond any reasonable doubt that the ''Work Breakdown Structure (WBS)'' is an exceptionally useful tool for planning, estimating, scheduling and controlling any kind of project.

	'''Annotation''': The aim of this book is to enrich the knowledge of each project and program manager on how Work Breakdown Structures work. Therefore, it analyzes the process of developing a WBS and also implementing it in the context of any project. Furthermore, there are several new concepts for Work Breakdown Structures presented within this book.

	The initial forms οf the Work Breakdown Structure (WBS) were developed by the U.S. Department of Defence (DoD) and the National Aeronautics and Space Administration (NASA) at the mid-1960s with a view to regulating projects which had the ultimate goal of enhancing military and space systems respectively. Moreover, the management of these projects was undertaken by a central administration office and many different industrial contractors were recruited in order to contribute to the accomplishment of the huge variety of tasks. So, the WBS tool was used to “…ensure that the total project is fully planned and that all derivative plans contribute directly to the desired objectives” (NASA, 1962). After two decades; namely in 1987 the Project Management Institute introduced the Project Management Book of Knowledge (PMBOK) which provided the necessary guidance on how work breakdown structures could be applied in any kind of project.<ref>Eric S.

	As we can see from '''Figure 9''', the top level of the WBS consists of a deliverable, which is the construction of the house and at the same time the main objective of the project. Moving to the second level, the number of deliverables is increased to three. The sum of the work rate of these deliverables is 100%. Also, the points that characterize each element represent the effort required to achieve that goal. The third level, which is the lowest level of this WBS, includes activities that require a greater degree of disintegration. Finally, the decomposition process can be continued by the project manager until he obtains the desired data.
