The Simple Way to Create a WBS

Here is a simple yet effective way to create a WBS and get it right.
Make a list of deliverables from the proposal, contract, and the scope statement.
From the list of deliverables, create sub deliverables that can be used to manage the work being done. In PMI terminology these are called work packages that define the amount of work that can be tracked by the project manager. These are not activities and tasks.
Sit with experts or knowledgeable staff from all areas of your project when creating the WBS. This means that for a software development project, the project manager should sit with at least four people: the UI designer, developer, tester and a software development manager who overseas the team. This is not too much. A 30-minute meeting with each person now will save the company in the long run.
Ask questions such as what next? How long? Who with? Etc. in order to nail down as much detail as possible. This is not necessarily part of the WBS but ensures that you have all the relevant information that may have been missed when building the plan.
Follow the 8/80 rule as a good rule of thumb that ensures that no task is less than 8 hours or more than 80 hours in the WBS. If a task is greater than 80 hours then it needs to be decomposed further into work packages.
