Which of the following components are included in the "Harmon" model?

The "Harmon" model emphasizes a holistic approach to business process modelling, focusing on various elements that interact within the framework of an organization. The correct choice highlights the key components recognized in this model: the external environment, suppliers, processes, and customers.

In this context, the external environment represents the broader conditions and factors that influence an organization, while suppliers are the entities that provide inputs necessary for the organization's operations. Processes pertain to the specific workflows and activities carried out within the organization, and customers refer to those who purchase or use the organization’s products or services. Together, these components reflect how an organization operates within its ecosystem, making it essential for understanding how business processes are shaped and function alongside external influences.

Other options, while they touch on important aspects of business processes, may not fully align with the specific framework that the Harmon model is focusing on. The components included in the other choices emphasize tasks, resources, competition, and goals, which are all valuable in their own right but do not encapsulate the comprehensive view of interaction and relationships that the Harmon model aims to represent.
