In this case, concepts were learnable analyst who had little prior training psychology or Human-Computer Interaction, flexible enough for make reasonable modifications fit design situation, but disappointingly ineffective predicting actual user problems. several hypotheses about cause low effectiveness, which suggest that additional knowledge, currently tacit CW-experts, could be used improve technique. addition, emergent picture process evaluator went through produce his sets realistic expectations other novice analysts contemplate Walkthroughs.
