According to this CIO article Change Management can be the bane of an IT managers existence. No matter how burdened end users are with ineffecient processes, outdated systems, and things that don’t work ‘quite right’, there will still be a core of resistance to change….any change. Resistance to change runs along a spectrum and not every end-user has the same reasons for opposition. An effective IT manager must corral the opposition forces (sometimes active, sometimes passive, sometimes both!) by evaluating what the source of opposition actually is. There might be change fatigue, fear, or distrust (will I lose my job?) Resistance may be spread geographically in individuals, or there might be certain locations that are more opposed to new-fangled ways.
The knowledgeable IT manager will address resistance on multiple fronts with multiple strategies. Give people advance notice. Involve vocal nay-sayers in development. Tie performance metrics to adoption rates. Hold town-halls introducing the solution, the time line, and the ultimate intent. Pilot the system or new software before a general roll-out. Include some of the resistors in the pilot. They might turn into your biggest cheer-leaders!
