UX Exam (modules 1-2) Flashcards
UX design is…
A philosophy & methodology, user/human centered, inclusive design
What is user centered design?
A design strategy that focuses on understanding people, their tasks, the technology available, and the large social and organizational context of where they live, work and play. Keeps the customer involved in the design process
What is the user-centered design cycle/process?
Plan, Understand, Specify, Make, Evaluate (ISO 9241-210)
What is involved in the ‘Plan’ stage of the 5 processes of user-centered design?
- Work out your approach – customise the lifecycle
- Assess and mitigate any risks
- Plan out the project but be prepared to iterate
- Planning-driven, not plan-driven
What is involved in the ‘Understand’ stage of the 5 processes of user-centered design?
- Observe the users in their real context
- Understand their characteristics, goals, tasks
- Understand the physical, social, technical environment
- Understand tools currently used and any problems
- Start with an open mind – not too focussed
- Progressively focus and hone in on the problems
What is involved in the ‘Specify’ stage of the 5 processes of user-centered design?
- Create research artefacts to communicate the context of use
- Describe the users’ needs
- Define attributes and behaviours of appropriate solution(s)
- User stories
What is involved in the ‘Make’ stage of the 5 processes of user-centered design?
- Outputs of this process are extremely varied
- Most often mockups or prototypes of a user interface
- Can also include anything else that will help to increase understanding of the problem and its solution(s)
- Designed as experiments
What is involved in the ‘Evaluate’ stage of the 5 processes of user-centered design?
- Test the design with users
- The results should either support or disprove your ideas
- Evaluation ≠ validation
- Usability testing ≠ user acceptance testing
What are the benefits of user-centered design?
- Enhances effectiveness and efficiency
- Improves human well-being
- Improves user satisfaction
- Improves accessibility
- Improves sustainability
- Counteracts possible adverse effects of use on human health, safety and performance
What are the 2 ISO standards for user-centered design?
ISO 9241: 11 Ergonomics of human-system interaction - Part 11: Usability: Definitions and concepts
ISO 9241: 210:2019 Ergonomics of human-system interaction - Part 210: Human-Centred Design for Interactive Systems
What is usability according to the ISO standard?
The extent to which a system, product or service can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use (ISO 9241-210).
What are the components of usability?
From ISO 9241-11:
* Effectiveness - “The accuracy and completeness with which users achieve specified goals” including:
o Accuracy - “The extent to which an actual outcome matches an intended outcome”
o Completeness - “The extent to which users are able to achieve all intended outcomes”
* Efficiency - “The resources used in relation to the results achieved”
* Satisfaction - “The extent to which the user’s physical, cognitive and emotional responses that result from the use of a system, product or service meet the user’s needs and expectations. This includes the extent to which the user experience that results from actual use meets the user’s needs and expectations. Anticipated use can influence satisfaction with actual use”
What are some problems with poor usability?
- Directly lead to success or failure of a website or system
- Loss of sales e.g. online stores
- Safety e.g. medical systems, airplane cockpit
What are the key principles of user-centered design?
ISO 9241:210:
* The design is based upon an explicit understanding of users, tasks and environments
* Users are involved throughout design and development
* The design is driven and refined by user-centred evaluation
* The process is iterative
* The design addresses the whole user experience
* The design team includes multidisciplinary skills and perspectives
What is user experience (UX)?
User experience (UX): A person’s perceptions and responses resulting from the use and/or anticipated use of a product, system or service (ISO 9241-210).
User experience includes all the users’ emotions, beliefs, preferences, perceptions, physical and psychological responses, behaviours, and accomplishments that occur before, during, and after use.
What are the periods and elements of UX?
Before usage: anticipatory UX
During usage: momentary UX, episodic UX
After usage: cumulative UX, reflective UX
Which is more important? User or business needs?
UX design is not about achieving user goals at the expense of business goals. Before even considering the specific site or system goals and objectives, it is an important need to understand business objectives, goals and priorities. Understanding these business needs would help define your project goals.
What are some methods to understand the current state of the site/system?
- Review site statistics and performance e.g. generation of sales or quotes compared with other channels such as call centres
- Conduct a site survey (also useful for benchmarking purposes)
- Talk to client facing staff - do they receive complaints about the site/system
- Review site/system feedback if available
- Have an expert review done by an external usability specialist or by an internal usability specialist not familiar with the site/system
- Conduct some brief exploratory usability testing
How can you identify target or potential users?
- Speak with business/content experts
- Speak with client facing staff
- Look at available customer data if available e.g. customer databases
- Look at any marketing reports or strategies
What is the basic criteria for a research participant in user research?
Research participants needs to be representative of your potential users, but it also requires to be inclusive.
How do you identify primary users?
Focus on people with:
* Similar tasks and goals
* Operating in the same environment
* With access to the same resources
Then:
* Within that population, aim for a wide diversity and range of characteristics
Who should you not be designing for?
- Don’t aim to design for the widest user population
- Don’t design for the average user – they often don’t exist
- Business stakeholders
