In my master thesis I aimed to design user interface for a website. Right now I have designed several mockups (around 25) that represent the user interface. I have to evaluate these mockups as fast as possible with the minimum amount of evaluators. Do you know how can I evaluate these mockups to check the functionality and usability concerned?
Do you have 25 different solutions for 1 website? or it's the number of screens you designed to represent a scenario? If all 25 are different solutions for 1 website, I think that you should have 3 or 4 at maximum, otherwise it's very possible that you are missing something really important about your website. Did you order the information on your website depending on your user needs? I think that could reduce the number of mockups: it will help you to exclude those that don't make sense for your user. For just usability, I suggest you to read "don't make me think" by Steve Krueg. It could help you at finding a few (fast) methods for usability evaluation. Hope that helps.
At first, it is very important to understand the objective of your website, and what it determines to achieve and who will be using it and why will they be using your website? And what do you want to test and why?
These are some of the basic questions to be considered during planning phase, as they will help you select an appropriate UX/Usability method.
Consider following things:
- Interested to evaluate navigation and information architecture of your site (mockup version site) --> If yes, Use Card Sorting, or Experience Maps
- You want to do objective usability inspection without a user. --> Use Expert review techniques such as Heuristic Evaluation or Cognitive Walk through
- You are interested to test how well users perform at your site, how many errors do they do during a certain task, their task completion rate on site. --> Use Task Analysis web usability technique, Observation and/or Interviews
- You are interested to test your mockup design A with mockup design B or you want to compare your mockup with a competitor's website --> Use A/B testing.
- You are interested to test your mockup design A with multiple mockup design (B,C--N) or multiple items on page. --> use multivariate analysis or multi-dimension comparison test.
- You are interested to evaluate user emotions, first impressions, attention, engagement, cognitive load satisfaction and expectations, --> Use quantitative surveys, open-ended questions, 5/2 First Impression test and/or physiological measures (eye-tracking, facial recognition, EEG brainwaves, GSR biosignals)
Hope it helps. If you have any further questions, drop me at my twitter. @Laghari_UX
I would use usability tests as an objective way to evaluate your mockups.
There are two different kinds of testing: formative usability testing, which aims for validates a concept and finds solutions. And summative usabilty testing, which just discover problems, counts them and gives you comparable metrics.
Here are some articles explaining both in detail:
