A key responsibility of the organization leadership is to lead the organization through change. Agile Adoption brings significant change to the way organization is used to doing things in traditional processes. Change is hard - it often makes people uncomfortable as we all get comfortable doing things certain way.
For Agile Adoption to be successful, organization leaders must learn the Agile ways of working and be able to speak the same language as their teams. Active engagement from leaders, following Agile best practices and motivating the rest of organization through change is an essential ingredient for an effective Agile Adoption.
