To familiarize herself with a user-interface of a software
system, a user needs practice. With practice, a user's think
time gradually decreases—the novice to expert transition. We
propose a queueing model that accounts for this transition in
analyzing the performance of a distributed software system.
We solve the model using deterministic simulation. Our
model captures system performance in terms of system
response time. We use the model to demonstrate how users—
who are at various experience levels in the novice to expert
continuum—may affect the system response time.
