There are a total of 20 iterations of this activity required for the project. The project activity takes 2.5 hours at its steady state rate and the learning rate is 75%. Calculate the initial output time for the first unit produced, using the learning curve formula: Y, = ax to the computerized accident-reporting and claims adju ment system you have in place. Your system is basic, will out many features, but it needs some general modification based on complaints from customers and claims adjuste at your firm. You know that your programmer is cap ble of handling 3 function points in a person-month a your programmer makes $60,000, so her cost is $5,000 month. The costs for the project are based on the followi requirements: Number of Screens 9 where Y, = the time required for the steady state, x, unit of output = the time required for the initial unit of output X = the number of units to be produced to reach the steady state b = the slope of the learning curve, represented as: log decimal learning rate/log 2 4 Function Input Output Interfaces Queries Files Complexity Medium Low Medium High Low 7 7 12
