First of all, you have to find the right people for your IT department. If you want to run a successful IT department, you need to hire the competent people for it. You should only keep those personal in the IT department who have the knowledge of the computers (hardware and software). You cannot expect a person from finance or marketing department to run the IT department. In addition, you have to assign the right designation to the right person. If you are looking for head of the IT department, then that person should hold at least a master level degree and a reasonable field related experience for the job. Besides, if you are searching for a communicator, you must hire a person who is good with business and computer as well. Moreover, if you want a technical leader for your IT department, you should hire a person who has good background of the field.
Hiring good people is not enough as you need to invest in good systems. You should first decide about your software and then hardware. It is very momentous for you to use registered software only to keep your systems well. After getting the registered software, you have to buy the hardware which will best complement the software according to its requirements.
The strategies of your IT department must be in accordance with the strategies of the overall organisation. Therefore, you must include the personal from the IT department in the decision making so as to integrate all the departments in strategy building.
You must keep on making the necessary changes in the IT department with the introduction of new technology in order to compete well in the market.
