Cookie-baking project: the recipe provides the complete statement of work, from which the work breakdown structure can be developed. The resources available for this project are two cooks and one oven with limited capacity; the raw materials are the ingredients to be used in preparing the cookie dough. As listed in following table, the activities take a total of 80 minutes of resource time. Because some activities can run parallel, the cooks should complete the project in less than 80 minutes. Following table displays some of the planning that will save time in the project. For example, once the oven is turned on, it heats itself, freeing the cooks to perform other activities. After the dough is mixed, both batches of cookies can be shaped; the shaping of the second batch does not have to wait until the first batch is complete. If both cooks are available, they can divide the dough in half and each cook can shape one batch in the same four-minute period. However, if the second cook is not available at this time, the project is not delayed because shaping of the second batch need not be completed until the first batch exits the oven. Description of Activity Duration (minutes) Immediate Predecessor(s) A. Preheat oven 15 minutes B. Assemble, measure ingredients 8 minutes C. Mix dough D. Shape first batch 2 minutes B 4 minutes C E. Bake first batch 12 minutes A, D F. Cool first batch 10 minutes E G. Shape second batch 4 minutes C H. Bake second batch 12 minutes E, G I. Cool second batch J. Store cookies Total time 10 minutes H 3 minutes F, I 80 minutes Imagine the start time is 8 am, use CPM (critical path method) to plan for this task.
