I am in the midst of adding about 100 images to one of my current projects after completing a round of usability testing on a low/medium fidelity prototype yesterday. I included ideas for 4 pages in the test. Finding and editing the images for this next round of testing could take a week or two and involve a good deal of back-and-forth with the client.
Page #1: 80% of users preferred version A over version B.
Page #2: Users saw two ideas. 55% of users preferred one of them; 45%, the other.
Page #3 showed users four ideas, and one of them was preferred by 80% of users.
Page #4 showed users three ideas, with some support for all three and no ideas getting a majority.
I'm doing this project as a volunteer for my portfolio. So saving time is important, but so is launching the sites on schedule, getting good press for this redesign, and landing future projects with paying clients. I'm planning two more iterations of usability testing after I get the site to beta (it is a WordPress site).
According to best practices, do I need to continue developing each of these ideas and show each idea again in the next round of testing? Should I throw out each idea that didn't win in this round of testing? Or which ideas should I continue to develop?
