Title: User problems, scenarios and storyboards


1
User problems, scenarios and storyboards
  • UCD Hoorcollege blok 1 week 7

2
Learning goals
  • By the end of the colleges and reading you
    should
  • Know what a context based scenario is
  • Understand the role of scenarios is product
    development
  • Know how to use personas to construct context
    based scenarios

3
Agenda
  • Types of scenarios
  • What is a context based scenario?
  • Steps in developing context based scenarios
  • The next stage
  • Summary

4
Types of scenario
5
Types of scenario
  • Alan Cooper identifies three types of scenario
  • Context based scenarios
  • Key path scenarios
  • Validation scenarios

6
Use of scenarios in product development
  • Each of these has a role in product development
  • 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

7
Context based scenarios
8
What are context based user scenarios?
  • Context based scenarios are stories (narrative
    tools) 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
    situation as is it is currently

9
Why persona based?
  • Personas are archetypes of the various users of a
    product (or people with a particular problem)
  • Personas have goals and behaviours
  • They want to achieve certain things and will
    behave in particular ways to achieve them
  • Personas allow us to construct a story of an
    ideal usage scenario to help us 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

10
Tasks versus goals
  • Tasks describe how someone makes a product
    achieve their goals
  • Goals describe what they want to achieve by using
    the product

11
Activity Discuss the following questions with
your neighbour
  • What task do I have to carry out when using an
    email system?
  • What goals might I have for when using an email
    system?

12
Goals first, tasks later
  • If we focus on tasks first we get into detail too
    soon
  • We do not know what is important and unimportant
  • We have not thought about the users real
    problems
  • The first questions should be
  • Why do they want to use a system (their goals)
  • What does the system have to offer to allow them
    to do this?
  • Goals allow us to focus on the why and what
    questions so that we can better fit the hows to
    the users goals
  • Context based scenarios allow us to focus on why
    and what rather than how in the initial stages of
    product development
  • (Of course we have to look at how to create a
    product, but this is done later in the process)

13
Steps in developing context based scenarios
14
Steps in developing context based scenarios
15
Create problem vision statements
  • The problem statement defines the objective of
    the product (or design for Cooper)
  • It defines what needs to change for both the
    personas (users) and the organization
  • The vision statement defines at a high level what
    the ideal solution will look like for both the
    user and the organization

16
Example
  • Problem statement
  • Company X has recently tried to grow its market
    share in the profitable 55 holidays market
    segment by 15, but has not been successful as it
    conducts its business online only. This is
    because 55 users feel that online travel agents
    lack the personal touch to design a holiday
    specifically for them and so they continue to use
    high street travel agents
  • Vision statement
  • Company Xs new online booking system will allow
    55 users to create individually tailored
    holidays comparable with those purchased at high
    street travel agents in a way equivalent or
    better than via a high street travel agent. This
    will allow company X to reach their goal of
    increasing their market share by 15

17
Brainstorm solutions
  • Brainstorming is a process of generating ideas on
    a specific topic quickly
  • In context based scenarios its role is to get
    your initial ideas for solutions out of your head
    so that you can look at the problem more openly
  • These solutions might not be the final solution!
  • But getting rid of preconceived ideas can open
    your thinking to other solutions

18
Identify persona expectations
  • The purpose of this stage is to identify the
    goals and expectations of the personas
  • Based on the personas you should be able to
    decide what they would expect the product to
    deliver (their end goals) and how they would
    expect it to work in an ideal world (their
    experience goals)
  • This can also be done via brainstorming too (but
    only after the solution brainstorming)

19
Construct context scenarios
  • Context scenarios are stories that put the
    persona into a real-life situation where they
    use the product
  • Imagine situations where the persona(s) have to
    use the product to achieve their goals in
    everyday terms
  • Write them down and storyboard them
  • Do not focus on tasks, just what they want to
    achieve
  • Pretend for now that the product is magic
  • Be general

20
Things to consider in constructing context
scenarios
  • What are the key activities that the persona
    needs to do to achieve their goals?
  • What is their expected end goal(s) from using the
    product
  • Where and when will the product be used?
  • Will be used for a long or for a short amount of
    time?
  • Is the persona frequently interrupted?
  • What other products are used with this product?
  • What is the skill, knowledge levels of the
    persona - is complexity allowed?

21
Storyboards
  • Cooper does not recommend making a storyboard for
    context based scenarios
  • However, they can be useful
  • Visualizing the story helps
  • Clarity
  • Consistency
  • Communication
  • We recommend that you do this here

22
Example storyboard
23
Identifying user needs
  • Having written (and storyboarded) your scenario
    you can now look to see what the user needs are
  • Needs consist of
  • Objects - actual things they need such as
    screens, buttons, etc.
  • Actions - things they need to be able to do such
    as sending email, paying, etc.

24
Next stages - good advice
25
Summary
  • Scenarios are used in the early stages of a
    product development process to
  • Identify user needs
  • Develop initial interaction design
  • Refine design and deal with exceptions
  • Scenarios are based on personas
  • Focus on goals not tasks
  • Context scenario development is the first stage
    of the process
