Work breakdown structure components

The work breakdown structure is therefore a method of describing the work to be done in the project in terms of deliverables and the tasks to be accomplished. It involves defining major deliverables and accomplishments during the project and fisting a hierarchy of sub-deliverables and accomplishments. The deliverables and accomplishments are a sum of their sub components and the WBS is a sum of all the elements. A more detailed description of this can be found in any of the general books on Project Management [D-13]. 

Thus, the charter must be complete enough to settle on these components of the plan. There are a number of project management tools that are useful, such as project network diagrams and work breakdown structures (WBS). The WBS is a deliverable listing by phase of the project. As the plan is developed, the list of issues to address should be expanded. 

Figure 15.3 provides yet another view of the supply chain project called the Work Breakdown Structure, or WBS. The WBS is a deliverable, or work product, view. For the supply chain project, this overall deliverable is the Implemented SCM Strategy shown at the top of the WBS. The components of the implemented strategy range below in the WBS structure. Projects A, B, and C, which could include partnership development, process improvements, or new systems or facilities, will also have their own deliverables. Table 15.2 summarizes each of the WBS deliverables. 

Level of assembly refers to the natural hierarchy of elements within a system. A system is composed of subsystems, assemblies, subassemblies, components, and parts, all of which can be categorized by level of assembly or system hierarchy. Level of assembly is a decomposition of a system into a hierarchy of levels that incrementally reduce the complexity description of the system. Levels of assembly are typically used for describing development, analysis, and test configurations of a system. This type of system breakdown is also referred to as system indenture levels and can also be part of a system work breakdown structure (WBS). 

The facility is divided into its systems, components, and subcomponents, forming a work breakdown structure (WBS). 

Table 2.1 shows a cost breakdown for a relatively simple plant for anunonium sulphate manufacture. The figures in the table correspond to the proportion of the total capital cost (%) with the 100% total at the foot of the last column. It can be seen that, in order to convert the main plant items (MPI) to a working system, many other cost components are involved, such as piping, support structure, civil engineering and foundations, etc. It is both surprising and significant that piping costs in this case (last column) are almost equivalent to the total MPI cost. In the case of...
