Student Name: _______________________ Student ID # : _______________________ GNG1103 Sample of Final Exam Page 2 of 15 PART A: True/False ( 10 marks ) Marks Achieved: _________ Indicate whether the statement in the table below is true or false. Each right answer is worth 1 mark. # Statement True/False Q1 Diversity and open-mindedness should be considered when creating a successful design team. Q2 An engineering design problem statement is a claim of up to four sentences in length that outlines the problem that will be addressed by the design process based on the customer's needs. It must be short, specific, and attractive. Q3 A metric is a measurable attribute which can be used to evaluate design solutions. Q4 Customer needs are always technical and reflect their perception and their vision of the world. Q5 To manage the failures and risks of a system designed, a planning poker technique can be used. Q6 To solve a design problem, engineering designers must consider functional requirements, non-functional requirements, and constraints. Q7 Any conflict is unhealthy and negative for the success and innovation of the team. Therefore, an effective team should always avoid conflicts. Q8 Positive as well as negative feedback can influence designer behaviours. Q9 FMEA is a powerful technique to manage projects and project risks. Q10 In an oral presentation, an effective presenter should pay more attention to verbal communication than nonverbal communication because verbal communication represents 65% of the entire communication.

Smaller than the product of the probability of failure of each component. B. Greater than the product of the probability of failure of each component. C. Equal to the product of the probability of failure of each component. D. Smaller than the probability of failure of each component. E. None of the above.

Rescue toboggans are used by ski patrollers and mountain rescuers to carry an injured skier or snowboarder safely down the hill where they can receive medical treatment. Rescue toboggans are usually made of aluminum or fiberglass. The table below shows some existing rescue toboggans on the market and their characteristics. RescueTob Inc. is a Canadian company specializing in designing, servicing, and manufacturing smart rescue toboggans worldwide. At RescueTob Inc., you lead a team of five engineers (you included) whose mandate is to design a new rescue toboggan to meet the needs of the customers and users whose statements are listed below: 1. I need a toboggan to transport injured people down the hill easily and safely. 2. When I get a rescue call, I need to take the toboggan up the hill. 3. I like when toboggan is cheap. 4. I don't like that it is hard to control. 5. If I lose control, there is no way to stop it. This is sad. 6. I don't like that it is heavy. It is better if it is more compact to store. 7. When there is a patient, I sometimes lose control and the stretcher becomes hard to stop. 8. I want to be able to determine the current location of the toboggan and the trained operators using it. 9. Most rescuers have a smartphone and I want them to be able to locate the toboggan with their smartphone. 10. I like when the toboggan app has alert functions to inform the nearest available rescuers and enable the real-time monitoring of injured persons. Apply the “Design Thinking” process to solve your specific problem , listing the specific steps that you and your team have taken to ensure a successful design. Explain how each step was applied to your problem and provide concrete examples for each . Justify your process and decisions along the way. The objective here is to show that you can apply what you have learned in the course to a real design problem, so make sure that you don’t just talk in generalities. Exhaustive detail is n ot required, but the amount of detail should be reasonable for each stage. You can focus your design only on the physical product or software product (app) . Note that the clarity, precision, and conciseness of your answers are important. Your solution does not have to meet all the customer statements listed above , but you should be clear about the customer and user statements that your solution must meet.
