The System’s Work Model does not fit the User’s Work Model
Any system forces a specific way for tasks to be done
System’s Work Model
Every user has an understanding of how a task should be done
Conceptual Model, Mental Model
For applications like the SIS the system’s model is hard to understand and work with because it makes no sense in terms of the work being done.
Causes errors, non-use
When presenting the ideas of system’s work models vs. user’s work model try to do it in the context of a poor application that the students could possibly identify with. For example, making schedules using SIS.
Any system we design imposes a specific way a task must be done – it imposes a model on the way work is done.
A key aspect (possibly the most important ) to designing usable systems have the systems work model fit user’s conceptual models of the work. The system should be a natural tool for the user to accomplish a task so they focus on the task and not the tool they are using.
Systems that do not fit the user’s work model can cause errors, mis-use, and non-use.
