Primary Endpoint: Iteratively unit test 4 tasks (A) Revise model platform and back end, (B) Refine the model taxonomy/characterization (i.e., ontology) and search module, (C) Revamp submission module, and (D) Implement paid modules) individually to ascertain 100% pass of common functionality (e.g., searching, uploading, and evaluating models) in the system back end and then iteratively perform integration testing via the front-end user interface until 100% pass using the System Usability Scale (as below). The System Usability Scale yields a single number representing a composite measure of the overall usability of the system being studied. To calculate the System Usability Scale score, first sum the score contributions from each item. Each item's score contribution will range from 0 to 4. For items 1,3,5,7, and 9 the score contribution is the scale position minus 1. For items 2,4,6,8 and 10, the contribution is 5 minus the scale position. Multiply the sum of the scores by 2.5 to obtain the overall value of System Usability Score; scores range from 0 to 100, with higher numbers being better.
Secondary Endpoints: Measure the success of Aim 2 by (1) completion of 80% of tasks in usability testing with scores of ≥68 on the System Usability Scale, a validated questionnaire, and (2) satisfaction with the site. Testing will focus on user interaction with the system, emphasizing effectiveness, efficiency, engagingness, error tolerance, and ease of learning. Specifically, the investigators will assess the ability of the project team and Advisory Panel member participants to log into the platform, configure and manage their modeling projects, and annotate or categorize them in accordance with an ontological index. The investigators will assign participants to interact with at least 2 randomly selected models and associated data files, iterating on this milestone until the investigators achieve 100% success.
