Dynamic Work Breakdown Structure (DWBS) is based on a single chart which is called "Tree Chart".
A tree chart is a Hierarchic orderly tree, where each node brick or son has a single father-like file in the folder.
The strongest advantage of the chart is that each work package is represented according to the basis on which it is built.
If work package W1.3.2 whose number in the Work Breakdown Stricture tree, is 1.3.2 and is under branch 1.3.
P2.5 is a product package numbered 2.5.
The system makes it possible to register, that work package W1.3.2 consists of product packages P2.5 from the Package Breakdown Structure and should be delivered as part of stage S1.2 from the Stage Breakdown Structure, while testing risks R3.1 from the Risk Breakdown Structure, for stakeholders H1.2 from Holders Breakdown Structure.
The use of such a methodology makes it possible to understand the motives of each activity and product in the project including the requirement to elaborate.
Using the tool it is possible to make better managerial decisions based on the demand-product-work done so far and the design that contributed to the process planning through the work packages.
A Framework of six criteria for Work Breakdown Structure completeness is given.
These criteria are:
1.The status of the work package is measurable. The task is adequately defined, and when questioned, the exact status can be given.
2. Events involving the start and end of action items are defined clearly.
3. All activities include deliverables. Action items should be clearly linked to a product that will be completed once the activity is completed.
4. Duration and cost are easily estimated.
5. The duration of activity follows the 8/80 rule. No work package should be less than eight hours nor should it be more than 80 hours.
6. Work packages are independent of one another. Once work has begun, it can continue until complete. Dependencies are noted, and a task that has begun should not stall because it has everything it requires contained within it.
