A core dimension in the model is Leadership and Emotional Intelligence. While agile approaches promote servant leadership and encourage shared leadership by team members, they do not explain Why or How best to achieve this. That is understandable, leadership is a huge topic, much larger and older than project management. However, there are some core concepts necessary for effective project delivery.
Likewise, in addition to leadership, emotional intelligence is a critical field of knowledge and skills also.
Emotional intelligence (EI) is the capability to recognize our own and other people’s emotions and use emotional information to guide thinking and behavior. It also allows us to manage and/or adjust emotions to adapt to situations and achieve goals.
Projects are commissioned by people for people and then undertaken with people. Assuming we can be successful at executing them by becoming experts at only the analytical steps of task estimation, scheduling, execution and tracking is missing the most important part of the picture.
It may initially seem overwhelming to think we need to learn the large topics of leadership and emotional intelligence to be successful on projects. The good news is that they overlap with the agile mindset and values anyway. The ideas of respect for workers and building empowered teams, leverage leadership and emotional intelligence. So, you are likely already using many leadership and emotional intelligence concepts in your everyday application of agile values and principles. Learning more about leadership and EI will just provide additional diagnostic tools and more strategies to apply when faced with challenging situations.
So, while there is likely more to learn, they are all useful net additional to what you already know. Like finding a secret door to an extra room in your house. You now have a whole new area to explore and make use of.
