In my time as a research assistant at a drug discovery & development laboratory, Work Breakdown Structure (WBS) was utilized to effectively break up the different tasks required to publish a new drug compound. The task breakdown included R&D, Drug Design, Chemical Synthesis, Assay Testing, and Publishing. In this case the project was broken down by phases to effectively keep all researches informed about what was required of them currently and what tasks still remained. Large broad category titles were given to general phases of the project while there were numerous smaller subcategories that were enveloped within each. Also, I believe that the type of breakdown of the WBS is highly dependent on the preference of the project manager. Each projects breakdown will come down to whichever way he/she is most comfortable approaching the task at hand.
