Sub Estimation Overview

You can use Function Point Modeler to define the sub estimation of each subsystem and to quantify each subsystem separately by using COCOMO cost factor. You can also use Function Point Modeler to define some factors for whole project by using COCOMO scale factor. Your project might contain two application systems, one of them is system A based on the J2EE and other is system B based SAP . You have to estimate your project as a whole. You can define the COCOMO cost factor in the CocomoBase estimation for whole project. You might create two CocomoSub estimation for the system A and system B.

You'll define sub estimations, assign COCOMO cost factor values of each sub estimation, etc. The sum of the CocomoSub estimations is the total project estimation.
