I saw your TR request just below a management article written by me titled, "New IT Manager: Hit the ground running". There are very few practical IT management training sessions that provide real world insight and tools to manage technology resources effectively.
The IT Manager Institute (www.mde.net/institute) includes a management process, lots of "how to" insight, complete set of management tools and tutorials, as well as possbily the first certification (IT Business Manager Certification) for IT managers based upon the business aspects of managing IT resources versus the technology aspects.
Your transition in becoming an effective IT manager is going to hinge on your ability to move from technology expert to a manager of people, projects, and processes. It's a difficult transition that many do not accomplish successfully because they continue to focus on the technology and don't learn how to focus on the business. It's also a big reason there is such a significant "IT business dis-connect" issue in most companies.
My web site has over 300 articles written to help IT managers of the world achieve more success. You're welcome to review them at www.mde.net .
In addition, two colleagues and I will be announcing the 20 Minute IT Manager Series very soon. Look for the announcement at www.20minuteitmanager.com in the next few weeks.
Best of success and congratulations on your promotion to IT manager.
