(a) Based on the materials that you learned in class regarding economic forces/variables their impacts, and implications for managers as well as the lessons learned (using interest rate, exchange rate, price fluctuations, inflation, unemployment and trade policies), develop a general decision-making model for identifying, analyzing and assessing, managing and responding to, and monitoring economic forces/variables that might influence organizations. The format of your proposed decision-making model should be analogous to a workflow diagram, illustrating the key steps, decision points, and processes involved in the procedure. Your output for part (a) should be an illustration of a decision-making model with the format of a workflow diagram. (b) Provide a paragraph to briefly describe and justify the effectiveness of your model.
