What are the approaches to developing the WBS?
The five approaches are: using guidelines; an analogy approach; a top-down approach; a bottom- up approach; and mind mapping. Using guidelines. The first technique in creating a WBS is using guidelines.
Which type of WBS is preferred?
Deliverable-oriented WBS structures are the preferred type according to PMI’s definition.
What is the top-down approach in project management?
The top-down approach to project management means that you start with the final deliverable (project goal) and break it down into smaller, more manageable tasks. These tasks can be further broken down into subtasks — great details — and then assigned to individual teams and/or team members within that team.
Why is it important to develop a good WBS?
The benefits of creating a WBS include: it defines and organizes the work required. it facilitates the quick development of a schedule by allocating effort estimates to specific sections of the WBS. it can be used to identify potential scope risks if it has a branch that is not well defined.
What is difference between top down and bottom-up approach?
While the top-down approach focuses on breaking down a big problem into smaller and understandable chunks, the bottom-up approach first focuses on solving the smaller problems at the fundamental level and then integrating them into a whole and complete solution.
Which is more accurate top down or bottom up WBS?
The top-down approach, in my opinion, generates a complete and more accurate WBS. In this approach, the WBS is derived by decomposing the overall project into sub-projects or lower-level tasks. This decomposition is based on general project characteristics and not on detailed design elements.
Which is the best approach for creating WBS?
Top-down Approach: Top-down approach states that you need to take the biggest task or module in the project and break them down. It requires more logic and structure and generally it is a preferred method for creating WBS.
What is Work Breakdown Structure ( WBS ) and the approaches?
A WBS is a deliverable-centric grouping of work activities, broken or decomposed into smaller task or work packages. The WBS defines and documents the scope of work within any project. The multiple approaches to create WBS are as described below (Schwalbe, 2012).
Is there a top down or bottom up breakdown structure?
There are essentially two ways to create a Work Breakdown Structure – the top-down or the bottom-up approach. The top-down approach, in my opinion, generates a complete and more accurate WBS.
