William's Journey to Success

CMI interviewed William about his route to Chartered Manager:

Describe your route to becoming a Chartered Manager?
I joined the Chartered Management Institute as a Chartered Engineer. I'd demonstrated my skills and abilities and it was then a relatively straightforward three-month process to becoming a Chartered Manager.

What challenges do you have as a leader and how has being Chartered helped you overcome them?
For me, a key challenge of being a leader is to get my team to adopt new ways of working. Becoming a Chartered Manager has enabled me to look in-depth at my management style and how I’m able to flex my leadership style to get the most out of my team.
