Before you do other kinds of testing of prototypes/concepts, do a quick round of testing with colleagues, or client people, or passers-by to identify the big obvious problems with your product/prototype/concept or your testing plan.
- quick feedback from someone not familiar with the concept
- identifying glaring problems with the concept/prototype, or testing techniques before more expensive testing
- robust, representative results
- because your colleagues or the client's staff know the area well already, you may overlook stuff that's not so obvious to normal people
How to use
- Make a basic version of what you want to test, and set up the test exactly as you would in the real testing. Testing sketches in the form of a 'paper computer' can be faster than making a clickable prototype from digital designs
- Grab a few colleagues and run through the test with them. Observe any snags in the testing technique and note down any problems they identify.
- Alternatively, sit in a cafe and offer to buy people a coffee and snack in return for 10mins of their time running through the test.
- Revise your prototype/stimulus/testing techique as appropriate.
Some of the bigger problems with your idea/prototype and/or your testing technique.
This can take as little as 30mins, or as much as half a day
What you need
- A testing plan
- A prototype or sketches to use in testing
- Money to pay for cake & coffee (if you're testing in a cafe)
- A cafe that's happy for you to sit there all afternoon (if you're testing in a cafe)
