Each participant received a laptop for repairs, computer access to the replacement guides, and an iFixit toolkit. One team member verbally outlined the test instructions, while another took notes of performance during the execution of the directions and timed the participants. Upon completion, both participants commented that the replacement guides were straightforward to comprehend. However, there were a few notes that were worth reporting:
For the hard drive, we realized we needed to add a “pry-up latch” connecting the white ribbon cable to the motherboard.
For the screen, our first action, “remove 2 screws” from the guide was omitted. Our user needed this indication to take off the screen. We went back and added in this action.
We will considered marking up the “black tape” as a contingency. However, we did not mention disconnecting the golden connector after removing the UPC tape. Our laptop came with black tape, so we planned to add notes for this issue.
For the motherboard, the participant had difficulty locating the power jack based on the photo used in the guide. We selected photos with the same camera angle to help the user undertsand the placement of the actions.
