These dependencies between activities and other planning factors are visualized and estimated in a Gantt diagram. In addition to that, the milestone is another determining factor. The beginning and end of activity are also determined by limitations commonly known as dependencies. The duration of an activity can be figured out considering the effort it takes to complete the designated tasks. Many activities can be combined leading to the summary activity. An activity typically comprises of multiple tasks and upon completion, the entire activity is completed. WBS is developed to establish a common understanding of project scope.Īn activity is referred to as the scheduled phase in a project plan with an individual beginning and end. WBS is part of the Planning process group and falls into Project Scope Management. WBS covers all the deliverable and all the work needed to be delivered on the Project By incorporating the cost accounts from the managerial breakdown structure and the project’s work breakdown structure, the whole business is capable of tracking the financial progress in addition to overall project performance. They are provided a specific budget to produce the defined deliverables. These departments or cost accounts are referred to as an organizational breakdown structure. Work packages refer to the lowest unit of work that a project can be segmented when developing your Work Breakdown Structure (WBS).įrom a cost viewpoint, the work packages are often put together and allocated to a particular department to carry out the work. If you are familiar with any detailed project schedules, then you will probably recognize the tasks under the work package that needs to be completed with a specific level of effort and in the allocated time frame. The work package signifies the list of tasks to accomplish a certain unit of work. At this point, the particular work packages are needed to produce sub-deliverables that are identified and assembled together. These sub-deliverables are eventually decomposed until only one person can be assigned. WBS helps to focus on communication and accountability at a level of detail required to manage a project. The project team typically develops the project work breakdown structure by determining the key functional deliverables and dividing those deliverables into further systems and sub-deliverables. Though it covers all the work in the work and only the work required but it’s not a contractual agreement. WBS visually defines the scope in manageable units that a project team can comprehend with every level of the work breakdown structure providing extended definition and detail. According to Project Management Body of Knowledge (PMBOK), a work breakdown structure refers to deliverable oriented classified decomposition of the work to be accomplished by the project team. 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. 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
