What other well known processes or approaches for creating an user experience (such as an app or website) exist except the user centered design approach and what are their strengths and weaknesses?
If you looking for different processes rather than methods, there are
- User Centered Design / Goal Directed Design
- Usability Engineering
- Design Thinking
- LeanUX / LeanStartup
- Data (or Metrics) Driven Design
- Open Innovation / Participatory Design
- Lead User Design / Design-driven Innovation
Four of them did I examine for innovation capabilites in a past thread (UCD and innovation):
So, one could say UCD is more an engineer attitude - problem found, problem solved. And in an engineers' attitude, all decision are traceable back to a requirement.
And Design Thinking is a designers' attitude - problem seen, play around, solution found. The ideation phase isn't really traceable, so the solution is a bit arbitrary.
LeanUx is out of a startup-mind - solution proposed, solution tested, solution refined. The emphasis lies on a fast product launch and gradual advancements.
Finally, Data Driven Design comes from a marketing perspective - set up business goal, test refinements, take best measured. It is not aiming for innovation, but optimization.
I'e always liked this overview of design decision styles by Jared Spool: http://www.uie.com/articles/five_design_decision_styles/
He lists: 1. unintended design 2. self design 3. genius design 4. activity-focussed design 5. user-focussed design
The last one is described as "This design style is the high-end approach and is necessary if the team is looking to create an excellent experience overall. To do that, the team will use user-focused techniques, such as field research and robust persona creation, ensuring the team understands the contextual nature of the users' experience." That, to me, is user-centered design.
The following are the different design methods:
User Centered Design
Goal Directed Design
LeanUX / LeanStartup
Data (or Metrics) Driven Design
Open Innovation / Participatory Design
Lead User Design / Design-driven Innovation
And yes! UCD and Goal directed design(UCD) are different. The reason for my deduction of considering the both designs as different is purely based on the fact the GDD is now evolving in a complete different direction. Also, There's no single opinion on this, as visible from the links. Please find the link here: http://dl.acm.org/citation.cfm?id=1621997 http://jonkarpoff.com/gdd-goal-driven-design/
There's also the Steve Jobs Approach:
Which is basically: If you want a big design breakthrough, don't ask people - just do it.
We figure out what we want. And I think we're pretty good at having the right discipline to think through whether a lot of other people are going to want it, too. That's what we get paid to do. "So you can't go out and ask people, you know, what the next big [thing.] There's a great quote by Henry Ford, right? He said, 'If I'd have asked my customers what they wanted, they would have told me "A faster horse." '
