Question

evaluate test data

choose engineers use a design matrix to identify the top two or three solutions, they build prototypes for testing. many tests provide numerical data that can be completed mathematically. every aspect of a solution can be tested, including the cost of materials and the time needed to implement the solution. three students are testing a parachute from the balcony of a design model to see how long it takes to drop. they will compare data from several tests and different designs to identify the best solution.

an important part of evaluating a design is building a design model and testing the model to measure the designs performance against criteria and constraints.

review the data and design

the purpose of testing is to provide data that can be used to evaluate solutions. after data collection, each solution is evaluated against the criteria and constraints. the data provide evidence about the strengths and weaknesses of each proposed solution. the data may also indicate ways a solution can be improved upon. using the data, team members can then provide constructive criticism of each solution. this analysis, which is based on evidence, helps to improve solutions.

1. sometimes parts of different solutions can be combined to make a better solution. what benefit does this offer? choose all that apply.

a. it allows for the best part of each solution to be used in a final design.
b. it gives the design team time to redefine the problem.
c. it allows the designers to meet customer demands for new designs every year.
d. it allows a solution to be developed that is better than earlier solutions.
e. it allows each test variable to be tested fully in each test model.

Explanation:

Combining parts of different solutions can leverage the best aspects of each to create a superior final design. It also enables the development of a better - overall solution compared to earlier ones. Option B is about redefining the problem which is not related to combining solutions. Option C is about meeting customer demands for new designs annually which is not the main benefit of combining solutions. Option E is about testing variables which is not the key benefit of combining parts of solutions.

Answer:

A. It allows for the best part of each solution to be used in a final design.
D. It allows a solution to be developed that is better than earlier solutions.
