I am an agile delivery manager, and quite good at what I do.
Recently switched roles, and now working in a larger organisation. Upon joining my new company I have made an instant impact and slowly helping senior management transform the organisation into a more agile environment. My work is starting to pave the way for a much more collaborative, transparent environment where teams are becoming self organised in an efficient way. This in turn has lead to being continuously praised by them, my reputation has also grown in such a short period of time to the point that people would like me to be the delivery manager on their projects or come to me for advise on how to improve ways of working.
Problem, some other delivery managers are acting passive aggressively. For example, this week I was tasked with running another delivery managers sprint by snr management who want me to understand that project's delivery process in case of sickness etc Their attitude upon returning from leave was to withhold information with regards to processes, become assertive at stand ups etc. when they were given clear instructions by snr management to let me finish the sprint.
We have a retrospective tomorrow, I have identified many bottlenecks, passive aggressive delivery manager doesn't want me to lead it. Snr management still do. They seem to be very protective of their project. I have tried to mitigate the situation by letting them know that I am happy to run the retrospective with them
What is the best way to handle these type of characters? I try to be diplomatic, is this the correct approach?
How do you get them on your side generally? It is frustrating for me to see this, since I would prefer to learn and work together as opposed to compete.
