Final answer:
The contingency approach is most suitable for Avec's organization in a rapidly changing environment, as it provides the flexibility and adaptation needed to respond to external changes.
Step-by-step explanation:
Considering Avec's organization is in a rapidly changing environment, the management perspective most suitable would be the contingency approach.
Unlike the administrative and behavioral perspectives which focus on hierarchical roles and large-scale group issues, respectively, the contingency approach emphasizes the importance of flexibility and adaptation to external changes.
This approach argues that there is no one best way to manage and organize because circumstances and factors vary greatly from one situation to another.
Indeed, Cinner and Aswani's recommendation for hybrid management systems underlines the significance of adapting to changes such as population increase, technological change, urbanization, and new legal systems. These can have varied impacts depending on the context of the organization.
Therefore, with this adaptive management perspective, Avec can incorporate various techniques and processes that are most applicable to their specific situation.
