Key question

What do we actually know, and what don't we?

It doesn't start with the solution, but with the question of what it is really all about. Those who decide what the outcome should be too early overlook the people they are designing for.

Learning objective: You are able to frame a design challenge, identify stakeholders, and prepare an interview.

Those who find the solution too early overlook the problem.

2.1 / Framing the challenge

Not too tight, not too wide.

A design challenge outlines the task the team is working on. If it's too narrow, the solution is already baked in: "Design a ticketing app." If it's too broad, nobody knows where to start: "Improve mobility."

A challenge is well-framed when it specifies a target audience and a need, but leaves open what the solution looks like: “How might we make the commute easier for commuters?”

The challenge defines the people and the goal, not the solution.

2.2 / Prior Knowledge and Participants

What we know, what we suspect, and who is affected.

First, gather what you already know and separate it from what you only suspect. Assumptions are permitted, but they must be tested.

OCCUPIED

Knowledge

Based on data, experience or sources.

SUSPECTED

Assumptions

Assumptions that are tested in the research.

OPEN

Knowledge gaps

Questions you cannot answer yet.

A stakeholder map shows everyone involved: users, decision-makers, employees and people who are indirectly affected. Pay particular attention to those who are often overlooked.

Assumptions are hypotheses, not facts.

2.3 / Preparing interviews

Good questions unlock stories.

Interviews reveal experiences, reasons and feelings. Open questions invite people to share stories: ‘Tell me about the last time you …’ Closed questions only yield a yes or no, while leading questions already suggest the answer.

Ask about specific experiences rather than opinions, and probe further with 'Why?'. Obtain consent before recording, and explain what the statements will be used for. You can find more about surveys and their limitations in Design Psychology, Section 8.4 Methods.

Ask about experiences, not opinions.

Review interview guide

Enter your questions. The tool highlights closed, leading, and duplicate questions and suggests open alternatives.

Your questions

  1. 01

    Do you use public transport often?

    Closed: can be answered with yes or no. Better: «Tell me about the last time you …» or «How do you go about it when …?»

  2. 02

    Isn't the app too complicated for you too?

    Closed: can be answered with yes or no. Better: «Tell me about the last time you …» or «How do you go about it when …?»

    Leading: suggests an answer. Phrase it neutrally, without your own opinion.

  3. 03

    Tell me about the last time you bought a ticket.

    Open and neutral: good for an interview.

  4. 04

    What was difficult about it?

    Open and neutral: good for an interview.

The check recognises typical patterns, it does not replace feedback. Read the guide to another person and ask how the questions come across.

Exercise

Stakeholder Map and Guide

Task: Prepare the research for your group challenge.

STEP 1

Frame the challenge as an open question.

STEP 2

Collect knowledge, assumptions and knowledge gaps on three colours of sticky notes.

STEP 3

Draw a stakeholder map: Who is directly affected, and who is indirectly affected?

STEP 4

Write a guide with five open questions and check it in the tool.

Evaluation: Which assumptions do you want to test first? Who did you almost forget?
