Textbook Question
Chapter 4, Problem 2P
An alternative airplane design is given here. Follow the assembly instructions and test the airplane. Are the instructions clear? Compare the performance of this airplane design with the one described in Problem 4.1. Which plane was easier to construct? How would you improve the design of this plane or the manner in which the design is communicated?
- Begin with an 8½ in. by 11 in. sheet of paper.
- Fold it lengthwise in alternating directions. The folds should be about 1 in. wide.
- Hold the top of the folded paper in one hand and fan out the back portion with the other hand.
- Make a small fold in the nose of the plane to hold it together, and let it fly.

Exploring the elements of design review questions
From the marketing and problem definition stages of the PDP, designers should have a list of Customer Requirements (CRs), from which Engineering characteristics (ECs) can be defined, and the design team necessarily goes through the trouble of translating CR’s into EC’s.
Why would designing off of CR’s be potentially difficult? And in what ways is designing based on EC easier or more beneficial?

The product design group of Iyengar Electric Supplies, Inc., has determined that it needs to design a new series of switches. It must decide on one of three design strategies. The market forecast is for
200,000
units. The better and more sophisticated the design strategy and the more time spent on value engineering, the less will be the variable cost. The chief of engineering design, Dr. W. L. Berry, has decided that the following costs are a good estimate of the initial and variable costs connected with each of the three strategies explained below.
Low-tech:
a low-technology, low-cost process consisting of hiring several new junior engineers. This option has a fixed cost of
$40,000 and variable-cost probabilities of 0.5 for $0.56, 0.1 for $0.47,and 0.4 for $0.41.
Subcontract: a medium-cost approach using a good outside design staff. This approach would have a fixed cost of
$75,000 and variable-cost probabilities of 0.7 of $0.49, 0.2 of $0.46, and…

Sara noted that because Granger has experienced such tremendousgrowth, the systems development process has evolved into its current state without muchdirection. Given Granger Container’s current size, Sara questions whether their currentprocesses are reasonable.

An artist has captured the experience in a drawing and is hoping to reproduce it and sell framed copies to current and former residents. He thinks that if the market is good he can sell 400 copies of the elegant version at $125 each. If the market is not good, he will sell only 300 at $90 each. He can make a deluxe version of the same drawing instead. He feels that if the market is good he can sell 500 copies of the deluxe version at $100 each. If the market is not good, he will sell only 400 copies at $70 each. In either case, production costs will be approximately $35,000.
