The evolution of lean six sigma at 3m, inc. (in the case studies section at the end of the textbook). read and reflect on the case study. in a 3 to 4 page double-spaced paper, discuss your answers to the five questions at the end of the case (under the heading, "challenges at 3m"). revisit chapter 7 in the text as you prepare your paper (lean thinking and lean systems).1. what are the benefits and costs of a lean six sigma program and how should they be tracked? 2. how should the various functional areas in the organization be included in the lean six sigma initiative, and what role should senior and middle management play in this change initiative? 3. do you agree with any of the points made by skeptics about the original six sigma program at 3m? explain why they believe that skepticism is warranted? 4. how will lean six sigma affect the innovative culture at 3m, and is lean six sigma enough? 5. how does lean six sigma in 3m differ from traditional tqm programs?

Your goal is to have $2,000,000. you have a total of $40,000 today. you invest the $40,000 and want to add to it each month. at 10% annual interest, how much do you need to invest each month in order to bring the total up to $2,000,000 30 years from now?

Suppose that xtel currently is selling at $40 per share. you buy 500 shares using $15,000 of your own money, borrowing the remainder of the purchase price from your broker. the rate on the margin loan is 8%. a. what is the percentage increase in the net worth of your brokerage account if the price of xtel immediately changes to (a) $44; (b) $40; (c) $36? (leave no cells blank - be certain to enter "0" wherever required. negative values should be indicated by a minus sign. round your answers to 2 decimal places.) b. if the maintenance margin is 25%, how low can xtel’s price fall before you get a margin call? (round your answer to 2 decimal places.) c. how would your answer to requirement 2 would change if you had financed the initial purchase with only $10,000 of your own money? (round your answer to 2 decimal places.) d. what is the rate of return on your margined position (assuming again that you invest $15,000 of your own money) if xtel is selling after one year at (a) $44; (b) $40; (c) $36? (negative values should be indicated by a minus sign. round your answers to 2 decimal places.) e. continue to assume that a year has passed. how low can xtel’s price fall before you get a margin call? (round your answer to 2 decimal places.)
