Teams make better decisions if they are interrupted with advice during their task, rather than advised before it, new research from UCL School of Management claims. In a study published in the journal Organizational Behavior and Human Decision Processes, Professor Colin Fisher of UCL looked at the timing and impact of formal interventions in decision-making groups. He found that giving teams advice ahead of time to prevent problems from emerging doesn’t work as well as interrupting them with in-process interventions.Decision-making groups value interruptive advice more, which leads them to share more critical information and make better decisions, compared to groups getting the same advice before they begin their task – even when the difference between receiving the information was only a few minutes.
