The common depiction of user centered design is misleading and wrong. My Plea: get rid of it!

  6. 6. 1: How are we going to get out of here? Not compatible with project conventions No criteria for breaking out Not kompatible with prevailing models Quelle: de.wikipedia.org/wiki/ISO_13407

  8. 8. 3: It’s just plain wrong • The Standard explicitly talks about „Interdependence“ of activities • …and clarifies… Quelle: ISO-9241-210:2100, S.11

  10. 10. OK, but… Why do I care?
  11. 11. User Centered Design helps Projects AND Users • User Centred = Evidence-based* • = strong Arguments vis-a-vis powerful stakeholders • = fewer Diskussions in Projects (and more productive ones) • = fester more efficient Projects • = Better Project Results, better UI *) i.Ggs. zu Meinungs-basiert
  12. 12. If UCD is not understood
 … It will not be practiced ? Opinio-based instead of Evidence-based Design Und damit leidet die Nachhaltigkeit von UX
  13. 13. Ignorance Centred Design (ICD) • No strong Argumente, why decide exactly 
 „this way“ and not differently • long and infertile Discussions in Projects • Weakly built Prioritization • Bad Project Results • Expensive Projects That leads to …

 It is misleading and wrong

  17. 17. One of my Approaches: 
 Rapid Prototyping /Rapid User Testing • Service Approach if clients cannot lock up an entire Team into a meeting room for a week without email • Similar to Google Design Sprint: No direkt upfront Context Research • User Test without Test-Report, instead: Clients observe Kick-Off & Requirements 1. Prototype & Feedback 2. Prototype & User Test Finalising & Handover Quelle & Copyright: Arno Bublitz Rapid Prot / Rapid UT Plan the User Centered Process ✅ Understand & Specify Context of Use ✅ Specify User Requirements ✅ Produce (iterative) Design Solutions to meet User Requirements ✅ Evaluate Design against Requirements ✅

  23. 23. My closing Appeal 1. Delete the „Process“-Diagram from your Slide Decks 2. Use the Standard as checklist and be flexible about Development Lifecycles, 3. Ask the awkward and painful Questions:„Do we really know our cusomters’ context? Do we really know what the customers want to achieve??“
