Discuss the company Apple, inc., which variance(s) you believe (is) are the most important one(s). You may focus on the cost variances that we discussed in chapters 9 and 10 or look at some that we did not get to look at or at least not in great detail, e.g. variances between budgeted and actual sales revenue or budgeted and actual cash in/outflows. Please share why you feel this variances is of crucial importance and how often you believe a manager should look at the reports (e.g. daily, weekly, monthly, quarterly).
