IT dictator . . .or maybe “IT benevolent despot”?
You are not only the IT manager, you’re also the leader, primary advocate, mood setter, chief technologist . . . & bottle washer . . . and, of course, the chief decision maker.
You are absolutely on the hook for decisions made in your IT department, and good management balance is key. If you are too nice and leave every decision to consensus or departmental “vote” you will be, and will be viewed as, indecisive, weak, ineffective and an obstacle to getting things done. If you take the approach of total dictator, you may miss key creative input and valuable information residing in the heads of your staff that can enrich and influence your decisions. So consider taking on the role of IT benevolent despot, i.e. an enlightened leader. When feasible, it can be valuable to get input from your staff and/or other knowledgeable parties, but at the end of the day, the decision is yours and yours alone. The good news is that you get to call the shots. Cool!
