![]() Correctness: the degree to which the system contains an accurate representation of the work (e.g., tasks that are left incomplete even though they’re finished.).(e.g., A task is described so vaguely that you don’t know what to do with it-think of writing “Mom” on your to-do list, when “Mom” represents “Plan mom’s birthday.”) If your system is meaningless, then the information it contains is hard or impossible to interpret. Meaningfulness: the degree to which the system is easily mapped back to the real world.(e.g., A task has a due date later than the due date for its project.) ![]() If your system’s ambiguous, the information in it can be interpreted in multiple ways.
