Of the eight conditions that are the signature of the highest-performing teams, there is one in particular that stands out âin study after study, irrespective of industry and irrespective of nationalityâas the single most powerful predictor of a teamâs productivity. It is each team memberâs sense that âI have the chance to use my strengths every day at work.â No matter what kind of work your team is doing and no matter which part of the world youâre working in, your team will always be most productive when more team members feel delight and joy in what they do every day.
