Control mechanisms can never be uniform in every country. International firms have to face severe constraints based on which they modify their control mechanisms in every country. Here is a list of major constraints that affect an organization in setting its managerial control mechanism −

●      Distance − Geographical distances and various forms of cultural disparities is a big constraint of control systems. Nowadays, email and fax transmissions have replaced the human communication, changing the meaning of distance among units and employees of an organization.

●      Diversity − It is hard to apply a common control system to everyone due to diversity. It requires the managers to be locally responsive to address the needs of the country in which the firm operates. Diverse attributes may exist in the form of labor, cost, currency, economic factors, business standards, etc.

●      Degree of Uncertainty − Data relating to the reporting mechanism may be inaccurate and incomplete, raising serious challenges to control mechanisms. Due to uncertainities, control mechanisms must focus on setting goals and developing plans to meet the goals.
