Simulation
Also Known As
Role Playing
Scenario-Based Evaluation
Description
Simulation is a form of (usability) evaluation in which realistic cases are created and the participant is provided direction on the use of the system or task.
Uses
During the design phase of the system to assess specific functions or design features.
When developing a training program on how to use the system.
To observe worker interaction in the nonwork (although simulated) environment.
How do I use this tool?
1. DETERMINE SYSTEM DESIGN AND FEATURES TO EVALUATE.
2. Once the system is sufficiently designed and programmed, CREATE SIMULATED PATIENT OR CASE with sufficient data in fields affecting the function and design being evaluated.
3. DEVELOP A SCRIPT to tell the user about the task they are to accomplish. This can be prescriptive - step-by-step, or general - ask user to complete a specific task with no directions or instructions.
4. OBSERVE USER while they are performing tasks assigned; take notes.
5. DEBRIEF USER upon completion of simulation; take notes.
6. EVALUATE RESULTS of evaluation and determine how to address results (e.g. system redesign; training, workflow modification).
Expertise Required
Users of this tool usually have some training or experience in its use.
Recommended Supplies/Materials
Data collection instruments
Advantages
Involves user in providing feedback on system design.
Can replicate work environment.
Provides feedback on proposed design.
Disadvantages
Participant-users may have unrealistic expectations.
Development of detailed script may be time consuming.
