Resource estimation
techniques to estimate resources
analogy with similiar projects
Estimated PM = PM of simmilar project
Est Dev time = ---''-----
performance of personnel with similiar projects
Estimated PM = Total Estimated PM / Average FP/PM for past projects
project breakdown
brake down a complex project into smaller project
critical path is established in this model of estimation
optimistic , likely, and pessimistics estimates
via LOC
Expected LOC , L= (a + 4m + 2b) / 7
where
a = optimistics LOC
b pesimistics LOC
m = Likely LOC
via FP
#
via PM
#
resource Models
COCOMO belongs to this model
dynamic models
take time into account
LOC = cK^1/3 T ^ 4/3
where
K = development effort
T development time in years
c = technology advancements
