Work Breakdown Structure (WBS) is a fundamental project deliverable that arranges the team’s work into manageable divisions. But, as things get more complicated, it’s crucial to understand the difference, and to do a good job creating each one. Well! yes on small projects, the difference doesn’t matter much. I understand that for many of us, the project manager it doesn’t make a lot of sense to have two activities as we usually deliver both in Single sitting and also as one document without a very clear demarcation between WBS and activities. Even in small projects, however, ad hoc or haphazard coding systems can lead to problems as the system is revised and extended over time.Before embarking our journey to understand the mentioned terms, let’s understand Decompositionĭecomposition as a means of breaking down scope into work package or work packages into smaller activities As a general rule, the record keeping and communication advantages of standard systems are excellent arguments for their adoption. In devising organizational codes for project activities, there is a continual tension between adopting systems that are convenient or expedient for one project or for one project manager and systems appropriate for an entire organization. Nevertheless, MASTERFORMAT provides a useful starting point for organizing information in different construction domains. Different coding systems have been provided by other organizations in particular sub-fields such as power plants or roadways. First, more specific information such as location of work or responsible organization might be required for project cost control.Īs a second problem, the MASTERFORMAT system was originally designed for building construction activities, so it is difficult to include various construction activities for other types of facilities or activities associated with planning or design. While coding systems provide a very useful means of organizing and communicating information, it has some obvious limitations as a complete project coding system. In North America, the most widely used standard coding system for constructed facilities is the MASTERFORMAT system developed by the Construction Specifications Institute (CSI) of the United States and Construction Specifications of Canada.Ĭoding Systems involve a hierarchical coding system with multiple levels plus keyword text descriptions of each item. Finally, electronic data storage and retrieval operations are much more efficient with standard coding systems. Common coding systems also aid in the retrieval of historical records of cost, productivity and duration on particular activities. A common coding system within an organization also aids consistency in definitions and categories between projects and among the various parties involved in a project. These codes reduce the length or complexity of the information to be recorded. In particular, coding systems are adopted to provide a numbering system to replace verbal descriptions of items. The use of a common nomenclature or identification system is basically motivated by the desire for better integration of organizational efforts and improved information flow. Each activity defined for a project would be identified by a pre-defined code specific to that activity. One objective in many construction planning efforts is to define the plan within the constraints of a universal coding system for identifying activities.
