You need to define your targets
Director, Best People
It seems as if you have run an effective IT department in your current company and, therefore, have reached the position of IT manager. You do not say what position you are aiming for in the company and what they want you to prove.
There are many facets to effective management and it seems that you have managed the technical infrastructure in a very competent manner, displaying the required competencies to do so, such as problem solving, organisation, speed of work, etc. I am speculating, but they may be interested in developing your people management skills, such as how you recruit, retain, develop and measure your staff. Or they may want to develop your management of the business, ie, how you communicate your objectives, successes and strategy against the broader corporate objectives. Communication here is key.
I am sure management in these areas is not an issue but it requires your bosses to define their areas of concern and what you need to prove - we all need targets, objectives and a development plan. Basically, they need to manage you. If this does not happen and it remains a mystery, you will find your experience marketable - probably as a technical IT manager.
