Mythical Man Month
\( T = \frac{E}{n^p} + bn + \frac{cn(n - 1)}{2} + pS \)

\( T \) = calendar effort (in months)
\( E \) = total effort (in man-months)
\( n \) = Number of people working on the project
\( p \) = Degree of partitionability (where 0 = not partitionable, and 1 = totally partitionable)
\( b \) = base training/ramp-up time (months per person)
\( c \) = average intercommunication overhead between two people (in months/person*person)
\( S \) = base sub-task communication overhead (in months)
