For this Outcome 3 in Design you will:• 3 Evaluate an existing product by:

• 3.1 Selecting evaluation factors which are relevant to the product selected

• 3.2 Planning a strategy for evaluation, using appropriate evaluation methods

• 3.3 Evaluating the product and presenting the results, including justification of the evaluation methods used

• 3.4 Drawing relevant conclusions in terms of the evaluation factors selected

• 3.5 Identifying ways in which design and manufacturing technologies impact on the environment and society

In this TASK 1 for DESIGN OUTCOME 3 your work will cover these 5 DESIGN OUTCOMES

2

• 1. Select a familiar product for analysis• 2. Select factors which have influenced the

design and manufacture of the product• 3. Plan a strategy for evaluating your product• 4. Evaluate your product and present your

findings• 5. Evaluate whether your plans for evaluation

were successful, useful and appropriate• 6. Comment briefly on how the decisions made

in designing and/or manufacturing the product will have affected the environment and society

(Activity sheets have a green background)

In this TASK(1) for Design Outcome 3 you will undertake these 6 ACTIVITIES

3

Activity 1 (T1/A1/D3.1)

• Select a familiar product for analysis.• Keep your selected product simple and

choose one which you are familiar with or have personally used.

• Write down the name of the product• Add an image of the product• What is the Primary Function• What are the Secondary Functions

Activity 1 - Selecting your Familiar Product

4

• fWhat is a Familiar Product?

A familiar product is one that you use everyday. The product you choose should be simple. Too complex and it will be difficult to evaluate well.

5


• Select factors which have influenced the design and manufacture of the product

• Check your factors are appropriate to your product choice.

Design Outcome 3.1• The candidate has suggested or identified which Design Factors are relevant to the task and the selected product.

6

Function (this factor deals with how well the product does the job it was designed to do)1. Consider the product’s goal.• Consider the screwdriver. The goal of a screwdriver is pretty

straight-forward: to drive screws. Although there’s certainly a lot of room for innovation in screwdriver design — there are screwdrivers with more ergonomic handles, ratchet-assemblies, magnetic tips, and exchangeable heads — ultimately everything in a screwdriver’s design is aimed towards the accomplishment of that single goal: driving screws.

Design Factors to consider (T1/A2/DO3.1)

Function• 2. Consider who will be using it. Perhaps the single most important consideration in the design process — and the one most often forgotten — is the intended audience for the product. What works perfectly well for one user might be completely dysfunctional for another. And if the hoped-for users fall more into the second category than the first, you’ve got a problem.

Design Factors to consider (T1/A2/ D3.1)

Function • 3. Is it clear how to use it?


The best design, as often said, "speaks for itself". It is immediately clear — at least to its target audience(s) — what a product does and how to use it. Clarity is key to functional design. Probably one of the best-designed objects in the world is the ball. With minimal instruction even infants can use it!

9

Function• 4. Is it engaging to your users?• A user acquires engaging experiences

when and after interacting with a product in a way that is frequent, intense, active, or vivid, etc.


10

Performance• http://

Market (1)• Who are the existing customers for your product?

• What are their needs from the product?

• What makes the product stand out?

• Does your product appeal to different groups of people with different needs or motivations?

Market (2)PricePrice too Low or too High or Just Right (Value for money)

• Product development

Design Factors to consider (T1/A2/D3.1)

14

Aesthetics• Elements of Aesthetics There are many different things that contribute to your overall perception of a product, and to your opinion as to whether it is aesthetically pleasing to you.• VISION• Colour• Shape• Pattern• Line• Texture• Visual weight• Balance• Scale• Movement


15

Ergonomics and AnthropometricsDefinition of anthropometrics and ergonomics• Anthropometrics is the comparative study of human

body measurements and properties. • Ergonomics is the science of making the work

environment safer and more comfortable for workers using design and anthropometric data.

• Select the best Design Factors to Evaluate your product against.

• Each Design Factor should be chosen from the six detailed previously.

• Choose the Design Factors that will best suit the product you have chosen.

Activity 2Plan a strategy for evaluating your product

For InstanceIn evaluating the design of a lamp Function, Market, Performance and Aesthetics might be your chosen design factors. Anthropometrics and Ergonomics might be ignored. However the light switch may need to be considered under Anthropometrics.

19

Use a Table similar the that shown below to indicate why you have chosen each design factor for your product.

Activity 2Select your Design Factors for evaluating your product and give your reasons

Plan a strategy for evaluating your product• The candidate has devised a plan for evaluation and they have considered the methods they will use — these will be, in the majority, appropriate to the product.• Once you have selected your design factors, begin to plan how you might evaluate your product against them. Be logical and ensure you can actually carry out the evaluations or tests. Keep personal safety and the safety of others in mind.Remember the purpose of an evaluation.Evaluation is a systematic determination of a subject's merit, worth and significance, using criteria governed by a set of standards

TASK1 – Design Outcome 3.2The candidate has devised a detailed plan for evaluation and they have considered the methods they will use — these will be appropriate to the product

21

• Methods of Evaluating a Producthttp://www.technologystudent.com/designpro/eval1.htm

• 1. User Experience• This is where several people use the product

and give their opinions on how well it worked. Their opinions must be noted. This can be in the form of a questionnaire. User trials can be used to test for function, performance, market, aesthetics and ergonomics.


Plan a strategy for evaluating your product 1

22

• User experience evaluation means investigating how a person feels about using a system (product, service, non-commercial item, or a combination of them).

• Detailed guidance for user experience evaluation is hard to give, since there are many different dimensions to consider when choosing the evaluation approach:

• Goal: Summative (score) or Formative (areas for improvement)• Approach: Objective or Subjective• Data: Quantitative or Qualitative• Utility: Does the user perceive the functions in the system as

useful and fit for the purpose?• Usability: Does the user feel that it is easy and efficient to get

things done with the system?• Aesthetics: Does the user see the system as visually attractive?

Does it feel pleasurable in hand?• Identification: Can I identify myself with the product? Do I look

good when using it?• Stimulation: Does the system give me inspiration? Or wow

experiences?• Value: Is the system important to me? What is its value for me?



23

Physical Testing• Test your product to see that it

works in the way that was intended. Record your results.

• Test for durability by repeating a simple drop test, decide on the height and repetitions of drops.

• Always inspect before and after the test and record your results.



24

Information Retrieval• Using any method available do research on how your

chosen product should perform against the Design Factors you are using to evaluate your product.

• Record the information you find.



25

• Use a similar table as shown below to write down which methods you will use to evaluate each design factor. Quick notes.



DESIGN FACTOR METHODS OF EVALUATING THIS FACTORAfter completing the table on the left you must now explain exactly how you will evaluate each factor in more detail.

You are now ready to begin your product evaluation and present your results.

The next set of slides will explain how to do this.

26

Activity 4 Evaluate your product and present your findings

• It is important that you display the results of the evaluations clearly and neatly. This can be accomplished by using the methods listed below.

• Tables of results with comments• Short reports• Pie and Bar chartsDisplay your results for each design factor. Some of the ways to do this are shown on the next two slides.

Activity 5 Evaluate whether your plans for evaluation were successful, useful and appropriate

• You must now comment (only short notes required) as to how successful your findings were in evaluating your product against each of the design factors.

• The purpose of this evaluation is for you to look back at all the different tasks you carried out during the evaluation of your product. Make Honest and Fair comments about how well they performed to evaluate the product.

Activity 6 Comment briefly on how the decisions made in designing and/or manufacturing the product will have affected the environment and society

• The next slides have examples of the types of presentations and issues you need to discuss.

• Comment on:• Materials your product is made from and where they come

originate• Recyclability of your product• Pollution during Production of your product• Pollution during use of your product• Power consumption of your product over it’s lifecycle
