Consider the following process chart that describes a mailing list process to recent Sprott School of Business alumni$$to contribute to a scholarship fund. The letters and envelopes were individually addressed $($mailing labels were not used$).$ The letters are to be processed $($matched with the correct envelope, time estimated to be $0\mathrm{.}2$ minutes each$),$ folded $(0\mathrm{.}12$ minutes each$),$ and stuffed into the correct envelope $(0\mathrm{.}10$ minutes each$).$ The envelopes are to be sealed $(0\mathrm{.}05$ minutes each$),$ and a large commemorative stamp is to be placed in the upper$-$righthand corner of each envelope $(0\mathrm{.}10$ minutes each$).$

A$.$ Estimate how long it will take to process $2,000$ letters. Assume that the person doing this work is paid $$17$ per hour. How much will it cost to process these $2,000$ letters?

B$.$ Evaluate the impact of each of the following process changes and indicate the resulting savings or increases in time and cost for processing $2,000$ letters $($note: evaluate each question separately$)$:

I. Each letter has the same greeting, $$Dear Alumnus or Alumna,$$ instead of the person$$s name.

ii$.$ Mailing labels are used and have to be put on the envelopes $(0\mathrm{.}10$ minutes each$).$

iii. Pre$-$stamped envelopes are used.

iv$.$ Envelopes are stamped by a postage meter that can stamp $200$ letters per minute.

v$.$ Window envelopes are used.

vi$.$ A pre$-$addressed envelope is included with each letter for contributions $($this adds $0\mathrm{.}05$ minutes to the stuffing step$).$

C$)$ Would any of these changes likely reduce the effectiveness of the mailing campaign? If so$,$ which ones? Why?

D$)$ Would the changes that increase time and cost likely increase the effectiveness of the mailing? Why or why not?
