Kim Scott's bestseller is normally read as a guide for managers but it provides equal value to the members of self-organized teams. While she details a number of useful models within the book, her main model which positions a culture of radical candor relative to others can provide a good basis for team improvement. The culture of the organization in which a team is formed will often dictate the default starting quadrant for interpersonal behavior.
In those companies where higher value is placed on playing nice rather than being effective or in those where conflict suppression is preferred to confrontation, team members may demonstrate behaviors consistent with Ruinous Empathy™. If a particular team member is constantly tardy for daily standups, rather than tackling the issue directly, other team members will internally stew but silently put up with it. Over time this will damage their relationships with that team member and will impact the synergy of the team.
Where the atmosphere of a company resembles a shark tank, Obnoxious Aggression™ might be the starting point. When that same team member shows up late once for a daily standup, they will be so thoroughly chewed out by one or more team members for having wasted time that the offender would be likely to set multiple redundant alarms to avoid ever being put through that particular wringer again! Feedback is provided in a timely manner when someone violates a team norm or isn't pulling their weight, but the method in which the message is delivered bruises egos and, over time, results in a culture of docile submission and low psychological safety.
If Petyr "Littlefinger" Baelish from Game of Thrones is considered a role model, then teams might start by exhibiting Manipulative Insincerity™. The team member who shows up late to standups will eventually receive feedback but only indirectly as a result of overhearing grumbling from other team members around the water cooler or through unnecessary escalation to his or her functional manager. Such passive-aggressive behavior not only delays the time for receiving and acting on feedback but it also erodes trust and reduces collaboration within the team.
One approach to address such dysfunctional behavior is to use Kim's model during a retrospective. Team members could brainstorm specific actions they witnessed (or themselves performed) which fell into one of the above three quadrants as well as recognizing other actions which demonstrated radical candor. This could be used to help the team enhance their working agreements or to identify specific interpersonal improvements. The challenge is that the team members need to be self-aware and willing to suspend their default behavior patterns in their participation. A skilled agile lead may be needed to facilitate such an event.
Psychological safety is critical within high performing teams. Knowing that your peers have your back gives you the confidence to experiment, to express vulnerabilities, and to ask for help when you need it. But another critical ingredient for building a good team is to cultivate a culture of radical candor.
