The baseline MCS software cost analysis is as follows
Effort = 465 Person-months
Schedule = 27 Months
Cost = $3722522
Total Equivalent Size =100000
Phase Distribution
Phase Effort (Person-months) Schedule (Months) Average Staff Cost (Dollars)
Inception 27.9 3.5 8.0 $223351
Elaboration 111.7 10.4 10.7 $893405
Construction 353.6 17.4 20.3 $2829117
Transition 55.8 3.5 16.0 $446703
all the baseline COCOMO II cost driver ratings are Nominal.
Relative to the baseline case, perform a return on investment analysis to calculate
ROI = (Savings - Costs) / Costs
for an investment in software tools for both the development cost savings and the lifecycle cost savings. Use the following information:
• The cost of the tools is $500K. This is the investment cost under consideration.
• The investment in tools will improve the MCS project's Use of Software Tools rating from Nominal to High for both the Development and Maintenance phases.
• Using the tools during development will reduce the MCS projects' Language and Toolset Experience rating from Nominal to Low. During maintenance, the experience with the tools will return the rating to Nominal.
