PE 10-1. You work as a lead BA for a parts manufacturer. Using the hybrid approach, at the time of initial visioning (see Figure 10-1), the company estimates the cost of systems projects using T-shirt sizing. Coupled with an estimate of the business benefits, this cost estimate is used to determine if a project is worth evaluating in more detail with more detailed requirements analysis and design work. Your firm utilizes the T-shirt sizing values shown in Table 10-1 and, further, assumes a "full-up" hourly labor rate of $90 per hour. You lead a software team that has been asked to create a T-shirt estimate for an epic user story: "As a plant manager, I want to be able to automatically schedule the assembly line so that I can more efficiently produce parts." Your team discussed the general idea of this requirement with the lead business customer for about an hour. Based on that, the team assigned a T-shirt value of XX-large to the work. This translates to an estimated development labor cost of (assuming that there are no other costs to consider in terms of infrastructure, etc.): 12 FTE months 160 hours per month $90 per hour
