Chapter 4. Breaking Work intoTask-Sized Chunks
When you organize a simple activity like seeing a movie with friends, you probably don’t bother writing out the steps. You just call your friends, pick a movie, get tickets, and buy popcorn without a formal plan. However, for more complex projects—like preparing your income tax return or launching a new product line—identifying the work involved is key to planning how and when to get it done. For example, missing the April 15 deadline can cost you hundreds of dollars in penalties. That new product may make a profit only if you keep costs below $100,000 and get it on the shelves before Thanksgiving. At such times, cost, delivery dates, and other objectives are important.
That’s where a WBS (work breakdown structure) comes in. Carving up the project’s work into a hierarchy of progressively smaller chunks until you get to bite-sized pieces is the first step to figuring out how and when everything will get done. If you’re new to managing projects, don’t panic—you’ve built a WBS before. The movie example in the previous paragraph is actually a simple WBS. The structure of a WBS is much like the system of blood vessels in your body, with the aorta representing the entire project and the smaller blood vessels as progressively smaller chunks of the overall work at each level (summary tasks).
