Critically evaluate the end product

In this lesson, we will critically evaluate our end product against the key specification points and identify the key strengths and areas for development, also considering the views of a range of end users. Please note this lesson will require some additional equipment, beyond a pen, pencil or paper, to fully participate. Please see the equipment slide near the start of the lesson video and make sure your child is adequately supervised if equipment is required.

A initial ideas.
Correct answer: A model of a final concept.
The final product.
Q2.
What is a design specification?
Correct answer: A list of specific points to describe how a product will look and function.
A series of sketches.
A way of evaluating a product.
Q3.
How might we test and evaluate the product?
We may create more sketches of the product.
We will compare the product to our initial ideas.
Correct answer: We will test to see if it works by comparing it to our design specification.

5 Questions

Q1.
How did we test and evaluate our final prototype?
Correct answer: We compared our end product to the design specification by testing it and identified what the advantages and disadvantages were.
We compared our end product to the initial ideas.
We created further sketches.
Q2.
Why did we test and evaluate our final prototype?
Correct answer: To check it against the design specification points by gathering feedback off users to see if it met all of the key points and identify what key improvements could be made.
To compare it to the initial ideas.
To see if we like it.
Q3.
What key components could we change to improve how the electrical system functions?
Correct answer: LED pattern or sound.
Sensors.
Switch.
Q4.
What could we do to change how the user interacts with the product? (Tick 2 boxes)
Correct answer: We could change how the user recycles the waste.
We could change the material we use.
Correct answer: We could change the type of sensor that we use.
We could change the user.
Q5.
We used a microprocessor for developing the electrical system, what is a microprocessor?
A microprocessor is a component that is used to make a simple circuit
A microprocessor is a very small personal computer.
Correct answer: A microprocessor is an integrated circuit that contains all the functions of a central processing unit of a computer. It can be programmed to support the control of key electronic components.
