WORK BREAKDOWN STRUCTURE PART 2 CASE STUDY 2.2 Automated Interdiction System (AIS) Workstation Project The project control manager, Karen, began to think about observing the results of her plans. She knew that cost data was collected by control account and that control accounts were grouped under Work Breakdown Structure (WBS) elements. Karen also knew that the WBS submitted with the proposal was not defined in sufficient detail to permit a meaningful analysis. The customer had provided two levels with the RFP, and her company added one level in its proposal. Unsure of her latitude in extending the WBS, Karen called her project manager, Broud Stearman, and arranged a meeting. Her meeting with Broud was enlightening. Broud agreed that the WBS had to be extended; he was un- willing to extend it by more than one level. Broud was convinced that too much granularity clouded per- spective. Also, the availability of too much detail could result in problems with the customer. There was nothing to hide. On the other hand, Broud liked the law of large numbers in formal reporting. Karen retrieved the Statement of Work (Attachment 1), the preliminary Configured Item Breakdown (Attachment 2), and the WBS (Attachment 3) submitted with the proposal. Several hours later Broud walked into Karen's office and offered to help with the extension - he also had a stake in the outcome of her work. Unfortunately, Broud was unfamiliar with software development activities. Using the SOW, the preliminary Configured Item Breakdown and the preliminary WBS: 1. Expand the WBS to provide better visibility of progress. 2. Do you agree with Broud that the WBS should be extended by only one level? 3. How should multiple builds be handled? 56 Section 1 Earned Value Project Management and Organization ATTACHMENT 1 Automated Workstation Statement of Work ITEM 0001 Design, develop, fabricate and test twenty (20) Automated Workstation Consoles in accor- dance with specification. 0002 Design, develop and test Automated Workstation Software in accordance with specifica- tion.
