Three different ways

Three different ways

The RED ZONE - PINK ZONE - GREEN ZONE concept is a way of describing the culture of an organization. The RED ZONE is a more adversarial, conflicted and hostile environment. The PINK ZONE is a more conflict avoidant, passive aggressive environment. The GREEN ZONE is a more collaborative, supportive environment. We rarely see an organization that is pure RED ZONE, PINK ZONE or GREEN ZONE; most are a unique combination of all three, to varying degrees. However, the chart below gives you a good indication of the difference between an organization that is primarily RED or PINK or primarily GREEN.

Radical Collaboration is a guide for individuals and organizations wishing to become more skillful at collaborative relationships.

The new 2nd edition of Radical Collaboration (HarperCollins, Jan. 2020) first explores the range of attitudes people bring to the task of collaboration and relationship building. A hostile, adversarial Red Zone attitude and a conflict avoidant, passive aggressive Pink Zone attitude is contrasted with a more effective and collaborative Green Zone attitude. Maintaining a Green Zone attitude is the single most important thing readers can do to increase their effectiveness when working to turn conflict into collaboration.

The book offers readers a series of practical tools they can implement immediately to create stronger, more collaborative relationships and organizations. Readers learn to better deal with their own defensiveness and that of others, negotiate their way through the conflict that is inevitable in any long-term relationships, solve problems meeting the interests of all the parties, and build more collaborative environments and relationships.
