Human performance data are reported for two dialogue conventions involving menu interactions with integrated facilities. Users prepared material for overhead foils in a six session experiment. An initiation style of dialogue in a flexible menu hierarchy was compared with a strict hierarchy involving explicit termination of dialogue sequences. Although tasks could be performed in the same number of steps with either interface, initiation had greater time and transaction costs than termination. The results are discussed in relation to the trade-offs that need to be considered in designing for navigational flexibility and to requirements for modeling user behavior.
