At a prior employer, I found myself with an IT team that had had little leadership. The applications team worked in a haphazard manner. The team was overloaded and projects were going nowhere.
Through my leadership and coaching, we first implemented Kanban to get control of the demand. Kanban allowed the team to focus on what was important, reduced the noise, and let them learn the new technical skills needed to succeed where we were going.
I provided the protection by handling all demands for service as well as any interruptions.
The team became a high performing team, delivering product every six weeks using Scrum.
More to the story, which we can discuss during a call.
