In simple terms, 3x3x3 encourages you to define three development goals, over a three-month period, engaging three other people to support you in those goals and hold you accountable. It's a framework that we use in varying forms to help ourselves put intentional learning into practice.
The holder of this badge defined 3 goals that will be achieved over a 3-month period and defined which 3 people can support in achieving this.
