MYP 5 Criterion D: Evaluating
Maximum: 8
Students evaluate the solution. At the end of year 5, students should be able to:
i. design detailed and relevant testing methods, which generate data, to measure the success of the solutionii. critically evaluate the success of the solution against the design specification
iii. explain how the solution could be improved
iv. explain the impact of the solution on the client/target audience.
Product testing
This is a stage in the design process where versions of products (for example, prototypes) are tested against the design need (specification), applied to the context and presented to the end-user or target audience. These tests may include the collection and analysis of data. Types of testing include:
User trial and observation: (usability and intuitiveness)
Field/ performance test: (functionality and performance)
Expert appraisal: (beta testing, consumer testing)
Authentic tests: The tests are relevant to the project and are completed by appropriate testers to gain high-quality quantitative and qualitative feedback
Strand (i)
Students need to a wide range of effective tests to evaluate the solution against the requirements of the design specification (including expert appraisal, user trials, field testing and user observation). For advice on testing methods refer to IBO Design Support guide Criterion D: Evaluating

i) Design Testing Methods
What Does This Look Like in Student’s Work?
Designs with detail (3-4) authentic product testing methods that includes (i.e. clearly describe who the testing was completed by; why is the test used; how many people; what questions were asked; what actions were performed; etc.)
Product tests provide relevant (accurate) feedback/data (both qualitative and quantitative) that will help prove the success of the product.
All testing results are summarised.
i) designs detailed and relevant testingmethods, which generate data, to measure the success of the solution
Strand (ii)
When critically evaluating the success of a solution, students must objectively judge the solution against the specifications. This objective evaluation comes from analysing the data gathered by carrying out the tests designed.
Students must analyse this data and make conclusions that identify strengths and weaknesses of the solution, along with opportunities for further development.

ii) Evaluate Success of the Solution
ii) critically evaluatesthe success of the solution against the design specification based on authenticproduct testing
What Does This Look Like in Student’s Work?
The student carefully considers the Design Specification and critically evaluates whether or not they were successful in meeting each success criteria.
The conclusions that the student reaches for each specification is based on authentic, effective testing methods, which are clearly described and referred to through evidence that prove his/her level of success.
The student clearly indicates overall whether or not they felt that they were successful in the creation of their final product In a concise manner identifying strengths and weaknesses of the solution.
Strand (iii)
Through the objective evaluation of their solution, students should have identified weaknesses in their solutions. These weaknesses provide opportunities for further development and allow students to consider how they would refine their solution further.
Students can suggest and undertake these improvements in many forms, including:
· written text—paragraphs or tables
· diagrams and charts
· annotated photographs/screenshots of the prototype
· sketches.

iii) Explain How the Solution Could Be Improved
iii) explains how the solution could be improved
What Does This Look Like in Student’s Work?
The student clearly explains a number of suggestions for how their final product could be improved.
The student provides reasons for why they would make these changes based on results of testing andexplains how making these changes would actually improve their final product.
The student provides evidence of making these changes to their manufacturing plan andimprovements to their product’s design.
Strand (iv)
To identify or predict the impact that a solution will have on a client or target audience, students must refer to the original problem, the design brief, the specification and the evaluation. Students should use these aspects to draw conclusions about how well the design brief has been met.
These conclusions may be presented in written form, as a list or as a table.
The following questions may help students to explain the impact of the solution of the client or target audience:
To what extent has the client’s or target audience’s problem been solved?
How does this solution improve the client’s or target audience’s situation?
To what extent has the design brief been met?
Are there any negative effects this solution could have?

iv) Explain the Impact of the Solution
iv) explains the impact of the product on the client/target audience
What Does This Look Like in Student’s Work?
The student clearly explains how successful the solution was in meeting the client/target market’s needs with reference to the Design brief and the original problem.
The student makes a number of suggestions for how these needs could be better met.
