Abstract: A requirement generation system receives user input selecting, from among key performance indicators stored in key performance indicator data defining key performance indicators available for selection in defining a requirement for a project, one or more key performance indicators to include in a requirement for a project. The requirement generation system defines the requirement for the project based on the received user input selecting the one or more key performance indicators and determines technical requirements for the requirement for the project based on mapping data defining formula and one or more data structures used in determining a measure of the one or more selected key performance indicators. The requirement generation system generates a data model mapping document for the project based on the determined technical requirements and outputs the generated data model mapping document.
