In order to determine the value of an alternative implementation for biometric enterprise architecture, Team Biometrics resolved to assess the relative cost of implementing and maintaining the software that comprises each implementation of biometrics enterprise architecture; the āAs-Isā (or current implementation) and the āTo-Beā (prospective implementation). The Team has created a Biometrics enterprise architecture using the CORE modeling tool, incorporating the requirements from our requirements document. Using that architecture an assessment of the function points was conducted and recorded in Function Point Basis Tables. These function points were fed along with other factors (cost drivers) into a cost modeling tool called the Constructive Cost Model II (COCOMO II) to arrive at a cost level of effort to produce and maintain both the As-Is and To-Be implementations of the biometrics enterprise architecture.
