     * Recall -- How much does the person remember afterwards or after periods of non-use?
     * Emotional response -- How does the person feel about the tasks completed? Is the person confident, stressed? Would the user recommend this system to a friend?
+Usability includes considerations such as:
+
+    * Who are the users, what do they know, and what can they learn?
+    * What do users want or need to do?
+    * What is the general background of the users?
+    * What is the context in which the user is working?
+    * What has to be left to the machine?
+
+Answers to these can be obtained by conducting user and task analysis at the start of the project.
+
+Other considerations
+
+    * Can users easily accomplish their intended tasks? For example, can users accomplish intended tasks at their intended speed?
+    * How much training do users need?
+    * What documentation or other supporting materials are available to help the user? Can users find the solutions they seek in these materials?
+    * What and how many errors do users make when interacting with the product?
+    * Can the user recover from errors? What do users have to do to recover from errors? Does the product help users recover from errors? For example, does software present comprehensible, informative, non-threatening error messages?
+    * Are there provisions for meeting the special needs of users with disabilities? (accessibility)
