What is evaluation? | Involves users and user representitives, in the technology design and development process in a structured manor. Capturing responses to a design or design artefact Can be carried out at ANY point of the design process |
What is the evaluation framework? | Why are you conducting the evaluation? What do you have to evaluate (prototypes?) Who is going to help you? (users, experts) When in the development process? Do you need a 'clean' environment, or context? What method are you going to use? |
What are some things to consider who is going to be involved? | Do you need to match against certain characteristics? Age, gender, education, prior knowledge Physical, cognitve and attidudunal implications Do any of your users pose particular challenges Older adults, children, children with special needs Can you use beginners, or experts? How many? (depends on methods) |
What are some factors for deciding when to evaluate? | Fomative (low fidelity) To inform the design process Exploratorive, using partically completed artefacts (prototypes) Maybe more qualitative or subjective Summative (high fidelity) A confirmation exercise To ensure intended aims are met Often against recognised standard or set of benchmarks |
Factors to consider when deciding where? | Use a usability lab earlier in the process Simulation where envirnment is safety critical Real World |
