10. concept definitions
Concept definition
➝ something understood, and retained in the mind,
from experience, reasoning and/or imagination *)
➝ a concept can describe something that does not yet
exist
➝ some parts of the product are explained, the rest is
left to imagination and reasoning
➝ generalizationor abstraction, of a particular set
of instances or occurrences *) features and
functionality
➝ concept description is a subset of a full product or
service description (e.g. detailed specification
document)
➝ a concept can describe also a product that already exists
➝ a high-level summary, not going into product details
➝ focusing on what is the meat of the product
Wikipedia
11. concepts for risk management
Concepting as risk
management
The earlier we discover that an
idea does not fly , the better.
OK
XX X
OK
➝ supporting product management decision making,
minimizing risks
➝ early and systematic validation of ideas
➝ if the product idea is a failure it would be good to realize
it when it is still a concept, not after launching it to a
global market
➝ for
small sw applications trial-and-error might be a
sufficient way to validate a concept idea
12. concept objectives
Concept objectives
objectives to...
summarize describe the essence of your product (idea)
visualize make your ideas more visible and concrete
convince some stakeholder (investor, product
prove a point management, product development,…) to invest
more on your idea
study different design and implementation
share to evaluate alternatives
to provoke discussion.
15. UX concept descriptions
UX Concept descriptions
My cool travel-mate concept
the level of detail of the UX concept description can
vary based on:
➝ maturity of your concept idea "
verbal à working prototype
➝ the target audience you are trying to impress: "
investors, product management, product development
➝ the next Go / No-go decisions to make; "
related to management or development
16. exercise
let s say you are handed a very detailed concept
description that you need to start to further design
and develop. What are the potential…
draw-backs benefits
• •
17. design drivers and inhibitors
UX Design Drivers
practical hedonic
➝ define the UX design drivers and inhibitors
➝ what would further the user experiences you are
targeting?
➝ what would stand in the way of it
➝ share them with the product development team
Adapted from: Roto & Rautava: User Experience Elements
and Brand promise (2008)
18. user segments
User Segments
➝ noteveryone will want to use your
product
➝ different user groups have different
needs and reasons for their purchase
and usage decisions
➝ there is no point to try to make a
design that will satisfy everyone
➝ segmentation is a tool identify
potential end users and end user
groups
➝ the
aim is to recognize user groups
where the product /service can serve
best and be most profitable
19. user segments example
User Segments Example
➝ technology enthusiasts
➝ keen on new technology things
➝ buy new technology items often
and they own a lot of devices and
equipments
➝ have larger than average income
➝ important to be the first ones using
the new technologies, no matter
the cost
➝ study functions curiously
➝ gather technology related
information
➝ compare features, functions and
prices before buying
➝ have high living standards
➝ like games, TV and movies
20. personas
User persona(s)
➝ Who is s/he?
➝ Where does s/he lives?
➝ What s his/her family situation?
➝ What is her/his lifestyle?
➝ What motivates her/him?
➝ What are her/his goals and needs?
➝ What is her/his profession?
➝ What is her/his relation to mobile
devices, computers, etc.?
➝ How much of her disposable income
does she/he usually spend on ICT?
➝ What does s/he look like? "
illustration or picture
➝ Other important issues related to your
persona, describe

• 4 min (in pairs)
• 9 min sharing (all)

23. scenarios
➝ persona-based scenario = concise narrative
description of how persona interacts with system
to achieve goals
➝ context-based scenario = how product can serve
needs of persona
➝ scenarios focus on illustrate requirements (the
WHAT), top-down decomposition leads to
functionality (the HOW)
24. use of scenarios in product development
each of these has a role
➝ context based scenarios are used to define user
requirements
➝ key path scenarios are used to define the
interaction framework
➝ validation scenarios are used to refine the design
and make sure it deals with exceptions and
special cases
25. what are context based user scenarios?
context based scenarios are stories that use
personas to describe what a user wants to
achieve through use of a product in order to
suggest a list of user requirements
they can also suggest what is wrong with the
situaon as is it is currently
26. why persona based?
➝ they are archetypes of the various users of a product (or
people with a particular problem)
➝ they have goals and behaviours – "
they want to achieve certain things and will behave in
particular ways to achieve them
➝ they allow us to construct a story of an ideal usage
scenario to help us to
➝ see how the UX can be improved
➝ develop (or change) products that allow users to
achieve their goals
➝ personas keep us at the level of goals rather than tasks in
initial development
28. UX benchmarking
UX Benchmarking
➝ What is the core concept?
➝ What kinds of UX targets might they
have?
➝ What kinds of tasks can users
perform with the application?
➝ What kind of UI solutions are there for
certain tasks?
➝ What are task times and task steps?
➝ What kind of visual design styles and
solutions are being used?
29. context ofthe context of use
Describe use
people
places mobile
things
time context
culture
31. prototypes and simulations
Prototypes and simulations
➝ visualize and simulate the product
concept
➝ representation of all or part of the UI
➝ for simulating the functionality of the UI
➝ a prototype can be a
➝ paper-prototype (even hand made)
➝ screenshots
➝ computer/terminal-based prototype
➝ flash demo
➝ anything that is complete enough that it is
possible for users to follow through the main
task flow
➝ usedifferent level of simulations or
prototypes for different purposes
32. why wireframing?
➝ fast
➝ lightweight
➝ early sense of UX
➝ spot potential problems early
➝ helps clients focus "
(no graphical design distraction)
➝ teaches you about the client (preferences/dislikes)
34. tips and hints
Tips and hints
➝ the bigger the risks related to your
product the more effort you need to
put to UX concepting
➝ use UX artefacts that are useful in the
later stages of product development
➝ usefulas input
➝ reusable
➝ consider carefully the appropriate level
of detail of your concept description
➝ do it only to the level necessary for the
next management decision
➝ the more effort you put into the concept
➝ the more impressive it will be
➝ the more disappointing it will be if rejected
