The involvement of human resources is a necessity in many organizations. In these organizations, there are processes that may require decisions taken by the human resources. The processes that are accomplished through human knowledge have irregular sequence of execution steps, i.e., the series of activities to be carried out are not structured. It is also important to guide such unstructured organizational processes and resources because they work towards the achievement of an organizational intention. Thus, designing models that serve as guide in order to achieve the organizational intentions are of prime importance. The intentions play a critical role in organizations because they motivate the organizational resources to work towards the overall development of an organization. Thus, supporting modeling of the intentions, strategies to achieve the intentions, capabilities required by the strategies, resources that provide the capabilities and processes that implement the strategies everything together in a holistic way is vitally important for any organizational modeling approach. The holistic way of modeling is required, because each modeling element requires modeling of its associated element. Traditional modeling approaches that are oriented to the sequence of activities, are not suitable when the sequence of activities cannot be determined in advance. Hence, there is a need for a modeling approach that enables creating models as guide in order to achieve an intention rather than providing sequence of steps required to achieve an intention. This master thesis work, proposes a modeling approach based on the derived requirements of the intention-oriented organizational modeling. The proposed approach allows creating organizational models that acts as a descriptive guide, e.g., providing information about the required strategies to achieve an intention. In the proposed modeling approach, the intentions are realized through the strategies which are associated with the capabilities that are satisfied by the resources. As a result, the unstructured organizational processes realizes the strategies that are associated with the capabilities, resources and intentions. A motivating scenario from an organization that belongs to the manufacturing sector is provided to help the reader in easily acquiring the concepts of the proposed approach. The approach is realized as a web-based modeling tool through which organizational models can be created. To assess, feasibility of the proposed approach and usability of the developed modeling tool, we also provide a case study centered around the motivating scenario.
