Question 1 (marks 10\%) Assume that the annual change traffic for maintenance (modification) of an embedded software system (comprising 72KSSI at the beginning of year 1 ) would be about 15% per year (6% is deleted code; 5% is the modified code; and 4% is the new code). Assume the cost driver (CD) of the system is nominal 1.5, and complexity factor (CF) is 0.93 for the modification. a) What would be the modification cost for year 1 if one MM costs QR. 1000 ? (4\%) b) How many staff should be recruited for this project if it is to be completed within 3 months in year 1?(2%) a) What would be the total size of the software in terms of KDSI (KSSI) after 3 years of maintenance with the same rate of annual change in every year? (4\%) You must show every step of your calculations. Only providing final computed value will attract O grade
