Assume that the system’s complexity is rated ‘complex’. Determine the following: i. FP for the software ii.
Given that the organizational average productivity for systems of this type is 6.5FP/pm. Based on a burdened labor rate of $8000 per month, the cost per FP is approximately $1230. Determine the effort in person-months and the total estimated project cost.
(6 Marks) (4 Marks)
b)
A system has 10 external inputs, 20 external outputs, fields 25 different external queries, (6 Marks) manages 4 internal logical files, and interfaces with 4 different legacy systems.
