Harvard ManageMentor — PROJECT MANAGEMENT TOOLS Worksheet for Developing High-Level Estimates Use this worksheet to divide a complex activity into smaller tasks—a process known as Work Breakdown Structure (WBS). Once tasks have been broken down into smaller, more manageable units, estimate the time, costs, and skills needed to complete each task. These high-level estimates will inform your project plan. Use multiple pages as needed. Description of the overall project: To obtain $100 in donations at a car wash on October 11, location will be the 7-11 on McCulock Rd and Alafaya. The car wash will start at 10:00am and end at 3:00 pm. What is the smallest unit of time that you want to schedule? For example, if you want to schedule to the nearest day, you will need to break down work to the point where tasks take a day to perform.
