Textbook Question
Chapter 2, Problem 11P
Suppose you are in charge of a large mailing to the alumni of your college inviting them to contribute to a scholarship fund. The letters and envelopes have been individually addressed (mailing labels were not used). The letters are to be processed (matched with correct envelope, time estimated to be 0.2 minutes each), folded (0.12 minutes each), and stuffed into the correct envelope (0.10 minutes each). The envelopes are to be sealed (0.05 minutes each), and a large commemorative stamp is to be placed in the upper righthand corner of each envelope (0.10 minutes each).
- Make a process chart for this activity, assuming that it is a one-person operation.
- Estimate how long it will take to stuff, seal, and stamp 2,000 envelopes. Assume that the person doing this work is paid $8 per hour. How much will it cost to process 2,000 letters?
- Consider each of the following process changes. Which changes would reduce the time and cost of the current process?
- Each letter has the same greeting,“Dear Alumnus or Alumna,” instead of the person’s name.
- Mailing labels are used and have to be put on the envelopes (0.10 minutes each).
- Prestamped envelopes are used.
- Envelopes are stamped by a postage meter which can stamp 200 letters per minute.
- Window envelopes are used.
- A preaddressed envelope is included with each letter for contributions (adds 0.05 minutes to stuffing step).
- Would any of these changes he likely to reduce the effectiveness of the mailing? If so, which ones? Why?
- Would the changes that increase time and cost be likely to increase the effectiveness of the mailing? Why or why not?

- Dyson, a high-tech home appliance maker, has cut ties with Malaysian supplier ATA IMS Bhd following an audit of the company's labour practices and allegations by a whistleblower. ATA is already under US investigation over forced labour allegations. Dyson has terminated its contracts and is in talks with its customer over the audit findings. ATA, which produces parts for Dyson's vacuum cleaners and air purifiers, tumbled 30% to its lowest since April 2020. The termination is a significant blow for Malaysia, a major electronics manufacturing hub, which has faced scrutiny this year over claims of abusive working and living conditions. Dyson terminated the relationship with six months' contractual notice, hoping it would give ATA the impetus to improve and enable an orderly withdrawal in the interests of the workers they employ.
