Increasing project complexity makes it substantially difficult to define project goals and thus predetermine deviations from an early stage on. Ultimately leading to delay and disruption. Despite being part of project delivery, no congruent claim management exists. A conducted quantitative survey among claim experts illustrates that current claim management models are not only time- and cost-consuming but also lead to little success. Furthermore, current models do not take the type and complexity of a project and a claim into account. However, complex claims require professional claim management to ensure sufficient causation and comprehensible quantification of entitlement. Therefore, the process design must be based on type and complexity of the project and the deviation. Agile contract models offer the possibility of adaptive organizational structures. Considering that with increasing complexity an increasing level of cooperation is needed, cooperative quantification may ensure a conflict-free process. Empirical data was gathered, allowing for the design of an adaptive organizational structure to assess claims. During the project design phase the complexity of the project is evaluated. Based on the results, an appropriate organizational structure can be integrated during the contract design. During project execution in the event of a deviation, its complexity is to be graded. Following the classification of the deviation, the appropriate contractual model can be selected.weiterlesen
