Model Comparison Summary

Model	Effort (PM)	Schedule (Months)	Team Size	Cost (@ $75/hr)
COCOMO	1.2	2.7	0.5	$14,793
COCOMO II	1.3	3.9	0.3	$15,205
Function Points	0.4	1.7	0.2	$4,238
SLIM	1.2	0.2	7.9	$14,793
Putnam	7.3	1.6	4.7	$88,145
AVERAGE	2.3	2.0	1.1	$27,435

Note: These are theoretical estimates based on historical models. Actual project costs vary significantly based on team experience, requirements clarity, technology choices, and project management practices. Use these as rough guidelines for planning and budgeting, not as precise predictions.
