    4. 4. <ul><li>Expert Review </li></ul><ul><li>Heuristic Review </li></ul><ul><li>Cognitive Walkthrough </li></ul>“ This is a more specific version of a design walkthrough, focusing on cognitive principles . Based on a user's goals, a group of evaluators steps through tasks, evaluating at each step how difficult it is for the user to identify and operate the interface element most relevant to their current subgoal and how clearly the system provides feedback to that action. Cognitive walkthroughs take into consideration the user's thought processes that contribute to decision making, such as memory load and ability to reason .” – Usability First (http://www.usabilityfirst.com/methods/cogwalk.txl) “ Heuristic evaluations usually are conducted by a small set (one to three) of evaluators . The evaluators independently examine a user interface and judge its compliance with a set of usability principles . The result of this analysis is a list of potential usability issues or problems. The usability principles, also referred to as usability heuristics, are taken from published lists . Ideally, each potential usability problem is assigned to one or more heuristics to help facilitate fixing the problem. As more evaluators are involved, more true problems are found.” – Usability.gov (http://www.usability.gov/methods/heuristiceval.html) “ Expert usability reviews are a fast and economical route to improving the usability of a Web site... The report outlines the criteria used to evaluate the site with reliable recommendations, which are based on extensive Human-Computer Interaction (HCI) research and experience .” – Mich. State Usability & Accessibility Center (http://usability.msu.edu/services_expertRev.asp)

    6. 6. <ul><li>Limited or no product team access </li></ul><ul><li>Limited UX resources </li></ul><ul><li>Limited time </li></ul><ul><li>No access to users </li></ul><ul><li>Access to working applications </li></ul><ul><li>This led me to create a process based on a twist of the product evaluation types… </li></ul>

    9. 9. <ul><li>Product Review Findings </li></ul><ul><li>“ Customers will not be able to use [Product name] outside of [Parent product name], therefore creating a barrier to use…” </li></ul><ul><li>“… providers could alter the recommendations without any indication to the user that these are ‘sponsored’ rather than purely calculated recommendations.” </li></ul><ul><li>Cognitive Walkthrough Findings </li></ul><ul><li>If the user selects the incorrect operation, in order to fix their mistake, the user must delete the new rule, and add another rule… </li></ul><ul><li>The colors do not support color blindness (red and green used) </li></ul>

    11. 11. <ul><li>Product Review Findings </li></ul><ul><li>It is unclear where the user should begin in order to make the system work, and would require a vast amount of training in order for the users to become proficient in the system. </li></ul><ul><li>Correct SeaChange product branding was not used. </li></ul><ul><li>Cognitive Walkthrough Findings </li></ul><ul><li>It is unclear how to access this application when receiving the hardware. </li></ul><ul><li>The content area pane is laid out well and supports the user’s work. The whole page or continuing page look helps users identify if they need to scroll to see more information. </li></ul>
