1. Method for determining a risk/reward model for a service to be provided by a service provider to a serviced entity comprising provision of a service provider value function for the service being dependent on at least one service provider value parameter, provision of a serviced entity value function for the service being dependent on at least one serviced entity value parameter, provision of weighting values for both the serviced entity value function and the service provider value function, provision of a serviced entity base case being characteristic for at least one serviced entity value parameter without provision of the service by the service provider, provision of a set of projects and their interdependencies being eligible for providing the service, each project having a given impact on a subset of one or both of the at least one serviced entity value parameter and at least one service provider value parameter, determining the risk/reward model by way of performing a selection of the set of projects, resulting in a selection set, taking into consideration the serviced entity value function, the weighting value for the serviced entity value function, the service provider value function, the weighting value for the service provider value function and the serviced entity base case and the risk/reward model providing a risk/reward line for the service to be provided relative to at least one serviced entity value parameter, the risk/reward line being characteristic for whether a reward or a penalty is accredited to the service provider depending on achieved results relative to the risk/reward line.
