Criteria and Constraints in Analysis

Mr. Regan explains how to identify criteria and constraints in problem-solving. Criteria are the requirements for a successful solution, while constraints are the limitations on these criteria. He provides questions to help differentiate between them and discusses qualitative and quantitative aspects. Examples using car design illustrate these concepts, showing how criteria and constraints guide the creation of solutions.

What is the primary focus when identifying criteria in problem-solving?

• Determining success requirements

• Identifying limitations

• Finding alternative solutions

• Evaluating past solutions

Which of the following best describes a constraint?

• A potential solution

• A requirement for success

• A limitation on criteria

• An optional feature

How can you determine if something is a criterion?

• By asking what must be done to succeed

• By identifying the limitations

• By evaluating past failures

• By considering alternative methods

What type of analysis involves looking at qualities that can be changed?

• Quantitative analysis

• Comparative analysis

• Qualitative analysis

• Statistical analysis

What question helps identify a constraint?

• What restrictions make it difficult?

• What must be done to succeed?

• What are the potential benefits?

• What are the alternative solutions?

Which aspect of analysis focuses on specific measurements or quantities?

• Comparative analysis

• Quantitative analysis

• Descriptive analysis

• Qualitative analysis

In the context of car design, which of the following is a criterion?

• The car must fit a minimum of four people

• The car must travel 50,000 miles without repair

• The car must have four wheels

• The car must be reliable

Which of the following is an example of a constraint in car design?

• The car must be a family vehicle

• The car must have a specific color

• The car must have four wheels

• The car must be affordable

In the car design example, what is a quantitative constraint?

• The car must be reliable

• The car must have four wheels

• The car must travel 50,000 miles without repair

• The car must be a family vehicle

What is the role of scientists when considering criteria and constraints?

• To ignore constraints

• To create solutions based on both

• To focus only on criteria

• To eliminate all constraints
