Smarter Faster Better by Charles Duhigg is a scientifically grounded self-help book that describes ways to increase productivity. Duhigg relates stories about ways to encourage individuals to make decisions and assign their own significant meanings to them, demonstrating that making choices and knowing the meaning of those choices stimulates further action and motivation. Analyses of team productivity programs and the functioning of effective teams show that productive teams should be diverse, call on every team member to participate, and create a safe environment for team members.
