Cognitive (Mental) model

Understand Your Users: Exploratory Studies

Motivational system Contextual knowledge & beliefs

  • A cognitive representation

(understanding) of how something works / organised

  • Based on previous experience &

beliefs; defines reasoning

  • Goals and tasks (“need”)
  • Desirability (“want”)
  • Emotional charge (“fears”,

frustration, pleasure, etc.)

Exploratory Study

Translating Needs Into Functionalities Make data actionable Where and when things go wrong in individuals work practice Points in time or space when individuals have a problem accomplishing the task that should

they are using Unpacking the tacit dimension for possible design solutions

Translating Needs Into Functionalities Make data actionable External influences - because: “Work takes place in a culture, which defines expectations, desires, policies, values, and the whole approach people take to work”

Beyer, Hugh, and Karen Holtzblatt. Contextual design: defining customer-centered systems.

Includes:

  • Influencers (represented as bubbles)
  • Extent of influence (overlap of bubbles)
  • Influences (as arrows - mind direction)
  • Breakdowns

Translating Needs Into Functionalities Make data actionable Physical objects that support the work (created and/or used in the process) -

because you want to know what objects people need and interact with

  • Structure
  • Related purpose and tasks

Physical work environment (plan) -

because you want to know how people adapt their environment to accomplish work

Includes: Complete with comments and notes

  • Structures that limit and define space
  • Walls, desks, file cabinets, etc.
  • Hardware, software, communication tools
  • Artifacts and their location in relation to

each other

Sequence

  • f

work steps and the intention behind steps - because you want

to know how work is organized in stages

Includes:

  • Intent behind step
  • Triggers, that initiate sequence
  • Steps, at a high level of details (actions, not

movements)

  • Loops and branches showing order and

iteration

  • Breakdowns (where things go wrong)

  • Interviewee (in the middle - circle)
  • Other groups/people (circles)
  • Physical/virtual places (usually rectangles)
  • Artifacts as they pass between people
  • Breakdowns (where things go wrong)
