Abstract: A communication and data processing system for use between one or more employers and one or more service providers, at least including a mathematical model for calculating a quantity Hi(T), where Hi(T) denotes a size of a fee to the one or more service providers and T denotes the true time use. Calculating Hi(T) at least includes using the following manipulated parameters: TN, estimated time for completing the project; T, actual time for completing the project; Z, chosen portion of total project value; and at least one parameter indicative of real-time data for the project. The communication and data processing system is implemented as an application on a computer, the application acquiring real-time data automatically at predetermined times and other parameters being entered manually via a user interface.
